DANSK DSF/IEC TS 63236-2 ED1 PDF

This part of lEC 63236, which is a Technical Specification, applies to d.c. appliance couplers 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 62368- 1. The accessories according to this part of IEC 63236 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;
