Product Introduction

1. Overview

Please read this manual in detail first before installing this equipment.

This equipment is mainly applied in computer room for frame power distribution. It is installed at the top of the frame in the computer room, providing direct current power supply and the alarm indication for the distribution frame.

 

Main function: With direct current (DC) power supply distribution system, configurable input is 0~300A fuses. The configurable output branches are 1A, 2A, 4A, 6A, 10A, 16A, 20A, 25A, 32A, 40A, 50A, 63A. The concrete capacity configuration is specified by the customer.

 

According to the profession standards, there are two alternating current (AC) electric outlets at the bottom of this equipment, it is provided to the customer’s testing instrument, etc. (when in usage, you have to connect external AC power supply)

Refer to Table 1-1 for the size and configurations.

3. Technical conditions

1) Adopt second-class distribution method;

2) Separate the working ground and the protection ground;

3) The direct current (DC) power supply is from inlet end to output end, allow the general voltage reduction no more than 0.3V at the rated loading;

4) All alarm signals are all not jammed;

5) It requires insulation electric resistance and stress.

Points to ground insulation electric resistance of the direct current (DC) power supply distribution system ≥ 30MΩ (direct current DC 500V measured).
