What is PD IEC/TS 62735-2 - DC plugs 5,2 kW for ICT equipment standards about?
PD IEC/TS 62735-2 which is a technical specification, applies to plugs and fixed socket outlets for class I equipment with two active contacts plus an earthing contact, a rated power of 5,2 kW, and a rated voltage range from 294 V to 400 V d.c. They are intended to power d.c. information and communication technology equipment only, products according to IEC 60950. The voltage between live conductors can fall down to 260 V d.c. when the voltage discharge value of the battery reaches the disconnecting level. The consequence is that the current increases accordingly. Plugs and socket-outlets covered by PD IEC/TS 62735-1 are intended for use in circuits where:
- Basic protection,
- An overcurrent protection (of 8,8 A or less for each socket-outlet or multiple socket-outlet),
- The fault protection (indirect contact protection), and
- Additional protection are already assured.
Who is PD IEC/TS 62735-2 - DC plugs 5,2 kW for ICT equipment standards for?
PD IEC/TS 62735-2 on DC plugs 5,2 kW for ICT equipment standards is useful for:
- Manufacturers of DC plugs and sockets
- Manufacturers of information and communication technology (ICT) equipment
- Concerned maintenance teams
- Product development / innovation / research teams
- Quality control teams
Why should you use PD IEC/TS 62735-2 - DC plugs 5,2 kW for ICT equipment standards?
The accessories according to this part of IEC 62735 are intended to be used by ordinary persons in data centres only where the value of the d.c. voltage distribution system is defined as follows:
- 380 V with a tolerance of ±20 V for installations with no backup battery or with a voltage regulation system
- 380 V with a voltage range of 294 V to 400 V for installations with a backup battery where voltage regulation is not guaranteed
- The voltage value between each live conductor and earth does not exceed 200 V d.c. during normal operation
- There are two abnormal voltage ranges (duration below 10 min):
- 260 V up to 294 V
- Above 400 V to 410 V.
The maximum current of the plug and the socket-outlet is
- 13 A when the voltage between live contacts is 400 V d.c.,
- 17,6 A when the voltage between live contacts is 294 V d.c.
and can rise up to 20 A when the voltage between live contacts decreases to 260 V d.c. for 10 min maximum.
Using PD IEC/TS 62735-2 guidelines you can apply to plugs and fixed socket outlets for class I equipment with two active contacts plus an earthing contact, a rated power of 2,6 kW, and a rated voltage range from 294 V to 400 V d.c. PD IEC/TS 62735-2 enables you to advance your services and provide your customers with suitable, reliable, and high-quality products.
