1 General
1.1 Using This Manual
This manual contains specifications and instructions to properly install and maintain the power supply system.
Component specifications and drawings are also included.
This manual contains information related to the operation and maintenance of the Alarm Control Unit (ALU),
the –48V/+24V Power Supply Unit (PSU), and the Distribution Module. Additional information is provided
on system status and alarms, troubleshooting, and system maintenance. Appendix figures of this manual
contains drawings, simple block diagram for different functional blocks and systems schematic.
Step-by-step procedures required for the installation and turn-up are detailed. All equipment parameter
setting, adjustments, and confirmation, as well as system monitoring, operations, and maintenance procedures,
are included.
Warnings are printed in bold, italic lettering. They alert the installation or maintenance craftsperson of a
potential hazard to either the equipment or the craftsperson if the warning is not followed.
1.2 Safety Notice
Delta Energy Systems is not liable for any hazards incurred by not following proper safety procedures.
Installation, operation, and maintenance personnel should always follow these safety rules:
1. Before installing the system, verify the AC input voltage and frequency, the AC breaker rating and type,
and other environmental conditions as noted in the specifications.
2. The system has passed stringent system testing prior to shipment. To avoid electrical shock. The
rectifier system requires a single ground point permanently connected to earth ground.
3. An AC breaker must provide adequate isolation between the system input and commercial AC main.
4. The environment should be dust free and controlled by an AC system. The area must be free of any
flammable vapors or fluids.
5. To avoid electrical hazard, the covers must not be removed on any component, including the ALU and
the rectifier.
6. Circuit breakers or fuses must be replaced with approved replacement circuit breakers meeting the
original design specification.
7. All connections must be made per the latest issue of the applicable national and local codes.

2 Product Description
2.1 Product Description
This power Shelf consists of modular rectifiers, an Alarm Control Unit (ALU), and a DC distribution
module. Up to four rectifiers and an alarm unit can be equipped on a shelf containing an integrated distribution
module. The rectifiers can operate from a universal range of AC line voltages. The High Line (HL)
operations are defined at an AC line input range of 165VAC~ 264VAC. The Low Line (LL) operations are
defined at an AC line input range of 90 VAC-130 VAC.
The system is controlled and monitored by the ALU. System level rectifier voltage settings, system
status, and alarms are displayed on the ALU. The system float voltage, equalize voltage, and alarm thresholds
are set from RMS. The ALU also provides automatic derating of the output power over the whole operating
line voltages. Figure 1 shows different functional blocks of the system.
2.2 Product Main Features
The Power Shelf has the following main features:
 -48 VDC/120 Amps, or +24VDC/200Amps, N+1 redundancy
 Modular design for scalable, cost effective expansion
 Front access for simple installation and maintenance
 High power density
 Active Power Factor Correction (>. 99PFC)
 High efficiency
 Temperature compensated float voltage control
 Alarm Control Unit
 Low Voltage Battery Disconnect (LVBD) (System equipped with PDU)
 Remote Monitoring and control
