The device safety standard IEC 62368-1 "audio/video-, information and communication technology equipment - Safety requirements" was published as an IEC standard ...
... for electrical and electronic equipment in the field of audio, video, information and telecommunications technology, including electrical business equipment, for nominal voltages up to 600 V in 2010 and should be implemented at European level this year. However, the EN draft was rejected because out of concerns about the undefined risks by the use of chemicals and inadequate protective measures against electric shock. Currently the committee is working on a new Draft of IEC standard. An implementation at European level will take place only after. As long as the harmonized EN 62368-1 standard is not available, the known standards EN60950 and EN60065-1 remain in use. Users must therefore continue to build to the CE statements of the relevant equipment, when using the Low Voltage Directive.
Contactless power transmission through inductive proximity coupling is becoming more and more popular.
According to current market forecasts in 2014 over 460 Millionen mobile phones, MP3 players and computers will be contactless and this doesn't take the multitude of solutions into account in industrial applications, electro-mobility and medical technology ...
From April 27th of this year, the additional requirements of the EC No. 278/2009 directive, pertaining to stage 2 must be enacted for external power supplies used in electrical and electronic equipment.
AC/DC power supplies, with an output up to 51 Watts may not exceed 0.3 watts in standby mode. In addition, the average efficiency during use may not exceed the following limits:
Average efficiency shall meet the following limits:
Power (P) |
No Load Power (Standby)
|
Output Voltage < 6V Active Efficiency |
Output Voltage 6V or > Active Efficiency
|
< 1W | 0.3W | (.497 x P) + 0.067 | (.48 x P) + 0.014 |
1W < 51W | 0.3W | (.075 x ln P) + 0.561 | (.063 x ln P) + 0.622 |
> 51W to 250W | 0.5W | 86% | 87% |
Power supplies must meet these guidelines and regulations to fulfill the requirements for CE labelling. The regulation does not apply to all power supplies. Those with outputs of 250 W or greater and those power supplies that provide multiple output voltages are not effected by the regulation. Also excluded are battery chargers and external power supplies for medical devices.
Other countries have similar guidelines and regulations for power supplies, such as:
USA Energy Star (+ California CEC)
Minimum Energy Performance Classification
- Level IV, for output power 0-250W: Standby power drain <0.5W / in operating mode, calculate efficiency: 0.09 * ln P + 0.5
- Level V for output power 1-49W: in Standby <0.3W in operating state calculated: 0.0626 * ln P + 0.622
- Level V for output power >49W: in Standby <0.5W / in operating mode > 87% efficiency.
- Level VI: in preparation
Australia (considers only the average efficiency in operation):
For output power from 1-49W: 0.09 * ln P + 0.49
For output power from >50-250W: > 84% efficiency
RRC power solutions products already meet these latest regulation and requirements.
