Approval Help and Guidance

This page covers safety and quality certification, along with approvals for power supplies and power conversion products.

 

Certification marks are evidence that a product conforms to applicable standards dependant on factors such as the intended location for use and the type of application itself.

 

Certification approval is awarded by a testing organisation (TO) which possesses the relevant authority given by a Certi?cation Organisation (CO). The decision to which testing laboratory to use to certify a product is dependant upon the application and where in the world the product is designed to be used. Each test ‘house’ specialises in a region. For example, a product which only has approval for use in North America cannot be legitimately sold for use in the UK as well.

 

Products that fail to comply with the required approvals carry stringent legal repercussions for the company selling the product along with the importer of the power supply and in extreme cases, such as personal injury or damage to property as a direct result of a power supply that does not meet relevant approvals, manufacturers of the power supply can also be investigated.

 

If a power converter or power supply is sourced, it should not be assumed that all approvals are adequate for the application or even genuine. For example, the presence of a CE mark does not automatically mean the product has met all required criteria to receive a CE mark due to certain suppliers only conducting an EMC test and CE marking the product. However, in order to correctly display a CE mark, the product should be EMC tested and carry the LVD and RoHS II approval.

 

Approvals are constantly being updated and it is the responsibility of the company importing the goods to ensure, through due diligence, that all documents are present and correct.

 

Ideal Power manage all safety and quality approval criteria of the power supply or power conversion product based on the intended application. If specific approvals are required by the customer to ensure that the product can be used for a certain application in a certain country, Ideal Power will work closely with the product engineers and the power supply manufacturer to obtain the correct approvals. This approach relieves the product design engineer and purchasing specialists of the responsibility to correctly specify, source and deliver a power supply with the relevant approvals and releases them to fully concentrate on the functionality of the product and application.

Approval, Standard and Certification Protocol


Certification Organisations (CO) decide on the definition of individual standards which includes conformity, regulation, restriction, future targets and testing protocol. For example, EN and IEC standards.

 

Test Organisations (TO) are official test houses that are internationally recognised to test to the standards set by Certification Organisations.

 

Please note, a Certification Organisation can also be a Test Organisation.

 

The general standard followed for power conversion and supply products (for ITE) is EN 60950. The internationally recognised version of EN 60950 is IEC from the International Commission on the Rules for the Approval of Electrical Equipment.

A brief list of Certification Organisations:

 

Test Organisation
A TO can test to any level that they have the authority to. They can test to any core standard, but as they are an authorised TO, it is more official.

 

A brief list of Test Organisations:


Self-Certification / Core Standard 

Anyone can test to a standard such as EN 60950, however the owner's liability increases and the credibility of the standard becomes highly questionable. Therefore most would choose to use a Test Organisation to gain relevant approvals.

IEC Earthing Classes
All electrical items are required to either have adequate insulation from the electric circuit or a physical conductor to electrical Earth (ground) to protect users from electric shock. The type of protection required is dictated by the design of the device and is segmented into class categories.

 

Class I
Class I devices contain a metal chassis which is fundamental to the operation and function of the product or it is an essential part of the structure. For some devices, both properties apply.

 

Class I devices must always be Earthed through an Earth conductor in the power converter or supply through the cable that connects the device to the mains electricity. The earth connection is achieved with a 3-conductor (wire) mains cable, typically ending with 3-prong AC connector which plugs into a corresponding AC outlet. One of those conductors will be a dedicated Earth connection which connects to the Earth circuit within the AC outlet.

 

Class I power supplies are equipped with the necessary connections to Earth.

 

Class 0I
Class 0I is for electrical installations where the chassis is connected to Earth (ground) with a completely independant Earth conductor which is separate from other connections and cabling.

 

Class II
A Class II device is designed in such a way that no conductor to Earth (ground) is required. A Class II power supply employs double insulation to ensure that no single failure results in a dangerous voltage or current being exposed which may cause an electric shock. Insulation in the power supply is achieved by a design implementing two layers of insulating material or a layer of reinforced insulation that encloses critical live parts of the circuit. 

 

 

 

Separated or Safety Extra Low Voltage (SELV)

SELV Logo

Extra-low voltage (ELV), in power supply, is one of several means to protect against electrical shock. Separated or Safety Extra Low Voltage (SELV) is a power supply that has an even lower operating voltage to further decrease the risk of electric shock arising from a fault within the power supply. To qualify as a SELV power conversion product or power supply, the voltage under normal and single-fault conditions must not exceed 42VAC or 60VDC RMS (71VAC or 120VDC Peak, for less than 200ms).

 

 

 

Protected Extra Low Voltage (PELV)
Dependant on which EN standard the power converter or supply conforms to (e.g. EN 60950, EN 60601, EN 60335 etc), it can be classed as a PELV product. In contrast to a SELV circuit, a PELV circuit can have a protective earth (ground) connection. A PELV circuit, just as with SELV, requires a design that guarantees a low risk of accidental contact with a higher voltage. For a transformer, this can mean that the primary and secondary windings must be separated by an extra insulation barrier, or by a conductive shield with a protective earth connection. 

 

 

 

Limited Power Source (LPS)

CE Mark

CE Marking Requirements

CE Logo

A CE mark is a combination of LVD / EMC / RoHS. Products carrying the CE marking represent a declaration by the manufacturer of conformity to applicable Electronic Commerce (EC) directives. The CE marking or formerly EC mark, is a mandatory conformity marking for certain products sold within the European Economic Area (EEA) since 1985. Products exported internationally made within the EEA will still carry a CE mark.

European Standards (EN)

EN Logo

A standard (French: Norme, German: Norm) is a technical document designed to be used as a rule, guideline or definition. EN standards are a protocol to follow when manufacturing a product or performing a function. European standards are maintained by European Committee for Standardization (CEN), European Committee for Electrotechnical Standardization (CENELEC) and European Telecommunications Standards Institute (ETSI).

 

Power conversion and supply products from Ideal Power are predominantly associated with:

  • EN 60950 - Safety Standard

Low Voltage Directive (LVD) - Current Mandatory Level: 2006/95/EC

LVD Logo

The LVD Directive covers all risks arising from the use of electrical equipment. The LVD 2006/95/EC standard is an outline of 11 safety objectives that all products with an input or output voltage between 50V and 1500V must meet before they can be sold and used in Europe. LVD will soon be aligned with the revised New Legislative Framework.

 

DC/DC converters will always need EMC and RoHS II approval, but rarely will they need to meet LVD approval.

Restriction of Hazardous Substances (RoHS II) - Current Mandatory Level: 2011/65/EU

RoHS

The full term for RoHS is: ‘Directive on the Restriction of the use of certain Hazardous Substances in Electrical and Electronic Equipment’.

 

The original RoHS directive was adopted in February 2003 by the European Union and has been in force since July 1, 2006 with the primary goal of restricting the use of hazardous materials in the manufacture of electronic and electrical equipment. RoHS was superseded by RoHS 2 on July 21, 2011 which contained further regulations and guidance.

 

RoHS II received an update on January 2, 2013 which further defined the directive. All Ideal Power products are RoHS 2 compliant.

Electromagnetic Compatibility (EMC) - Current Mandatory Level: 2004/108/EC

EMC Logo

EMC refers to the unintentional electromagnetic interference (EMI) that a power converter or supply may generate as a by-product of operation. Complying to EMC 2004/108/EC ensures that the power converter or supply has been designed in such a way as to limit the generation, propagation and reception of electromagnetic energy. This means that the unwanted effects of EMI such as preventing the correct operation of other electronic equipment or the interference of them can be regulated to low and acceptable levels or stopped completely.

 

The standard to which a power converter or supply must conform to is dependant upon the application of the device. The main standard will have a variation attached to it which is specific to that application.

 

An example of which is below:

 

Standard Variations for Applications
EN 55022 X
EN 55024 X
EN 61000 X

Energy Related Products (ErP II) - Current Mandatory Level: 2009/125/EC / EC 278/2009: External PSU

ERP II Logo

In November 2009, the Eco-Design Directive EuP was replaced with the new energy-related products directive (ErP) 2009/125/EC. The ErP directive is also known as the Ecodesign of Energy Related Products Directive and compliance.

 

ErP II is considered a green and environmentally-friendly directive with the aim of constantly improving the energy efficiency of energy-using products (EuP) and energy related products (ErP), specifically when in a standby or sleep state, but it also applies to the general design and operation of the device. Not only does this save energy in general which is positive for the environment, but it also offers potential utility bill savings for end-users.

 

A clarification of the difference between EuP and ErP can be found below:

  • Energy-using Products (EuPs), which use, generate, transfer or measure energy (e.g. electricity, gas, fossil fuel), including consumer goods such as boilers, water heaters, computers, televisions, and industrial products such as transformers, industrial fans and industrial furnaces.
  • Energy related Products (ErPs) which do not necessarily use energy but have an impact on energy and can therefore contribute to saving energy, such as windows, insulation material or bathroom devices (e.g. shower heads, taps).

 

This also applies to power converters and supplies that are connected to a mains AC socket which is switched on (live) but no device is connected to the output. A mobile-phone charger would be example of this type of power supply or an internal power supply unit (PSU) where the device is in a low-power mode such as sleep or standby.

 

Manufacturers must show an active interest in redesigning their products to lower the impacts associated with production. Manufacturers must also appropriately label products so that consumers can review product impacts.
