Safety Standards
----Our chargers were designed & produced referring to following standards, if you have any specific requests or need other third party official certificate besides the following, please contact with us for details. We shall discuss case by case.-----
The safety of the component parts is an important consideration in equipment design. However, a part-by-part analysis of component quality and design is too time consuming for design and quality personnel. To get around this problem, safety standards have been designed to assure component safety. The following section describes the safety standards with which Oriental Motor is concerned.
_ EN Standards (EU member states)
The European Union continues to coordinate the industrial and safety standards of individual member states
under the aegis of the Council of European Standardization (CEN) and the Council of European Electrical Standardization (CENELEC). The unified standards for all of Europe are called the Harmonized Standards. The numbers for Harmonized Standards all begin with an “EN”. EN standards apply to the design and manufacture of products exported to the EU area. (IEC and VDE standards apply when an EN standard has not yet been enacted.) Certification is given by private inspection organizations such as TÜV Rheinland, VDE and DEMKO. Qualifying products may display the various safety marks.
_ Construction
_ Devices to Prevent Overheating
UL, CSA, EN and IEC standards require that any equipment using a motor also possess a device to protect the motor from overheating which can be caused by overload, intentional or unintentional locking of the rotor,etc. All Oriental Motor approved products include impedance protection or thermal protectors in the motor (brushless DC motors excluded).
_ Insulation Materials
Oriental Motor’s motors and fans have class E insulation (World K Series, V Series, and BH Series have class B insulation). The insulation class indicates the division of heat-resistant grades, and is specified as shown in the table below by JIS C4003 (IEC60085). Also, the insulation is certified as class E by EN/IEC standards (World K Series, V Series, and BH Series are class B) but recognized as class A by UL and CSA
standards (World K Series, V Series, and BH Series are class B).
_ Minimum Spacing Between Live Materials
To prevent accidents caused by short circuits between live materials or between live materials and user-accessible materials (normally not live materials), minimum spacing distances between such materials have been defined. All Oriental Motor products comply with the relevant requirements.
_ Degree of Protection
IP X X
_ DC Fans
These fans include solid state control circuitry that incorporates a limiting, current shut-down circuit, which controls the fan during locked rotor conditions. Bimetal Pure Silver Contact Points Lead Wires
_ Overheating Protection Devices
Overheating may be caused by overload, no load or extremely small load, intentional or unintentional locking of the rotor, or use in very high ambient temperatures. This results in a drastic shortening of the life of the insulation system or, in extreme cases, fire.
_ CE Marking
To distribute equipment within the European Union, the CE marking is mandatory for certifying that the equipment complies with EC Directives (safety). To obtain a ruling that the equipment satisfies the required
items of each directive, the manufacturer must usually verify that the equipment complies with the EN standards applicable to the EC Directives or, if not available, with the IEC standards. The manufacturer then composes a declaration stating compliance with the directives and applies the CE marking. (However, depending on the risk of danger, formal testing by an approving authority may be required and the selfcomposed declaration is then issued after receiving proof of formal testing.) Products with a declaration of voluntary compliance have the following mark either on the nameplate or on the package label.
The major scope of compliance and period of obligation are as follows:
EMC directives: 89/336/EEC, 92/31/EEC
Applicable to equipment that could cause electromagnetic interference (EMI) and equipment that could be affected by electromagnetic interference (EMS). (Mandatory as of 1January 1996)
Our 24V4A_5A_6A_8A_10A were applied EMC approval as
EN60601-1-2
EN12184
Other charger models also design & produce understand these standards. But if you need third party official certificate for other models. We need evaluate the certificate applying cost according to your purchase expectation.
Low voltage directive: 73/23/EEC
Applicable to equipment used with 50-1000 VAC or 75- 1500 VDC. (Mandatory as of 1 January 1997)
Our 24V4A_5A_6A_8A_10A were applied LVD approval as
IEC 60601-1
EN60601-1
Class II double isolation security
Other charger models also design & produce understand these standards. We need evaluate the certificate applying cost according to your purchase expectation.
