BS PD IEC/TS 62735-1:2015, which is a Technical Specification, applies to plugs and fixed socketoutletsfor class I equipment with two active contacts plus an earthing contact, a rated powerof 2,6 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 accessories according to this part of IEC 62735 are intended to be used by ordinarypersons in data centres only where the value of the d.c. voltage distribution system is definedas follows:

  • 380 V with a tolerance of ±20 V for installations with no backup battery or with a voltageregulation system;
  • 380 V with a voltage range of 294 V to 400 V for installations with a backup battery wherevoltage 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, and
    • above 400 V to 410 V.

The maximum current of the plug and the socket-outlet is

  • 6,5 A when the voltage between live contacts is 400 V d.c.,
  • 8,8 A when the voltage between live contacts is 294 V d.c.

and can rise up to 10 A when the voltage between live contacts decreases to 260 V d.c. for10 min maximum.

The voltage between live conductors can fall down to 260 V d.c. when the voltage dischargevalue of the battery reaches the disconnecting level. The consequence is that the currentincreases accordingly.

The accessories according to this part of IEC 62735 do not require maintenance.

Plugs and socket-outlets covered by this part of IEC 62735 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.
