Product Description

EPS30-4815AF Power System

The AC-powered cabinet uses the EPS30-4815AF power system to convert the AC input into the DC power for power distribution.

Function

The EPS30-4815AF power system converts one AC input into two DC outputs to implement the DC power distribution. It can be connected to one set of batteries and use its monitoring module to manage the batteries.

The EPS30-4815AF 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 EPS30-4815AF power system work in the load balancing and mutual hot backup mode.

Indicator

Table 4-3 describes the indicators on the rectifier module of the EPS30-4815AF power system.

Table 4-3  Indicators on the rectifier module of the EPS30-4815AF power system

Indicator	Status	Description
RUN	Steady green	The rectifier module functions properly.
	Off	This indicator is off when the red indicator is on or the yellow indicator is on (not caused by output overcurrent).
ALM	Steady yellow	The ALM indicator of the rectifier module is valid when PS-off, OTP, and primary protection are valid, or when overcurrent occurs.
	Blinking yellow	The communication of the rectifier module is interrupted.
	Off	The rectifier module functions properly.
FAULT	Steady red	The FAULT indicator of the rectifier module is valid when PS-enable and Vo-OV are valid, or when fan fault, no output, or output short circuit occurs.
	Off	The rectifier module functions properly.

Table 4-4 describes the indicators on the monitoring module of the EPS30-4815AF power system.

Table 4-4  Indicators on the monitoring module of the EPS30-4815AF power system

Indicator	Status	Description
RUN	Green and blinking 1s on and 1s off	The monitoring module functions properly.
	Blinking green quickly	The monitoring module hardware is normal but the communication between the monitoring module and the upper device is abnormal.
	Off	The monitoring module is faulty or there is no power input.
ALM	Steady red	The system generates a critical alarm or the battery is disconnected.
	Off	The system does not generate any critical alarm and the battery is already connected.

Input Terminal

The EPS30-4815AF power system supports one 220 V AC power input and the standard 3-pin connector is used.

Figure 4-2 shows the input terminals of the EPS30-4815AF power system.
