EPS75-4815AF Power System

EPS75-4815AF Power System

The AC-powered cabinet uses the EPS75-4815AF power system to convert the AC input into the DC and then distribute the power.

Functions

The EPS75-4815AF power system converts one AC input into six DC outputs to implement the DC power distribution. It can be connected to one to two sets of batteries and use its monitoring module to manage batteries.

The EPS75-4815AF power system can also use the external sensor transfer box to collect and report the status of sensors and standby detected parameters.

NOTE:

The rectifier modules of the EPS75-4815AF power system work in the load balancing and mutual hot backup mode.

LED Description

Table 6-23 describes the LEDs on the rectifier module of the EPS75-4815AF power system.

Table 6-23  LEDs on the rectifier module of the EPS75-4815AF power system

LED

Status

Description

RUN

The green LED is on.

The rectifier module works in the normal state.

The green LED is off.

This LED is off when the red LED is on or the yellow LED is on which is not caused by the output overcurrent.

ALM

The yellow LED is on.

An alarm has been generated for the rectifier module. The possible causes are as follows:
  • The AC power is cut off or no AC power is supplied.
  • Over-temperature protection is enabled.
  • Primary protection is enabled. Specifically, the rectifier module automatic protection function is enabled due to a high voltage on the AC input end.
  • Overcurrent protection is enabled. Specifically, the rectifier module automatic protection function is enabled because the DC output current of the rectifier module exceeds the current range supported by the rectifier module.

The yellow LED blinks.

The communication of the rectifier module is interrupted.

The yellow LED is off.

The rectifier module works in the normal state.

FAULT

The red LED is on.

The rectifier module is faulty. The possible causes are as follows:
  • The AC power supply is faulty.
  • The output voltage is 0 V.
  • The fan is faulty.
  • The rectifier module output is short-circuited or does not work.

The red LED is off.

The rectifier module works in the normal state.

Table 6-24 describes the LEDs on the monitoring module of the EPS75-4815AF power system.

LED

Status

Description

RUN

The green LED is on for 1s and off for 1s repeatedly.

The monitoring module works in the normal state.

The green LED is blinking quickly.

The monitoring unit hardware is normal but the communication between the monitoring unit and the upper layer device is faulty.

The green LED is off.

The monitoring module is faulty or there is no AC power input.

ALM

The red LED is on.

The system generates a critical alarm or the battery is disconnected.

The red LED is off.

The system does not generate any critical alarm and the battery is already connected.

Input Terminals

Figure 6-25 shows the input terminals of the EPS75-4815AF power system.

Figure 6-25  Input terminals of the EPS75-4815AF power system

The EPS75-4815AF power system supports one 220 VAC input. The connections of the power system are as follows:

  • The AC-L terminal is connected to line L of the AC power cable.
  • The AC-N terminal is connected to line N of the AC power cable.
  • The grounding point is connected to the PGND cable.

Output Terminals
