DC POWER SYSTEM
DCPS
12KW WITH DISTRIBUTION
The La Marche DCPS system offers a complete DC power solution
in a compact package configuration (4RU). DCPS system can be
installed in standard 19 or 23 inch rack or cabinet.
La Marche DC system utilizes high efficiency rectifiers, a highly
intelligent system controller, I/O interface board for alarms/
sensors, and a load/battery distribution panel. This complete DC
system offers battery management with low voltage disconnect,
remote monitoring, remote configuration and configurable alarm
contacts.
The compact design of the system reduces space requirements and
installation cost. The system is configured with 48V/50A high
efficiency rectifiers to provide a rated output current up to 200A.
The DC distribution section is comprised of 16 pluggable load
breakers and 2 battery breakers.

CONTROLLER (DCSC)
Controller Front Panel
La Marche’s DC System Control (DCSC) is an intelligent
module that monitors and manages La Marche DC power
systems. The controller provides the system with Battery
Management, Energy Conservation, Rectifier Management,
Intelligent Battery Hibernation Mode, Battery Testing,
Battery Charging, and Current Limiting controls.
System configuration settings and real-time parameters can be
accessed either locally (through a two-line LCD display), or
remotely (through a Web User Interface).

DCU Port Description
Equipped with the I/O module (DCU), the controller
supports configurable digital inputs, alarm dry-contacts and
site sensor ports for environment management and alarms
reporting. The DCU I/O module provides the ability to add
multiple sensors for: ambient temperature, humidity, water,
door status, smoke and battery temperature.

The dry-contacts alarm are configurable and can be
customized upon the DC system’s requirements. All alarms
can be easily configured and monitored remotely through the
WebUI (Web User Interface). See page 4 for details.

DC RECTIFIER (DCR)
The DCR50 rectifier converts AC power to DC power and
utilizes high performance features, such as high efficiency
(>96%), high power density, walk-in start, complete
protection and low noise. The output voltage of the rectifiers
can be adjusted through the DCSC controller. The
rectifier is hot swappable, providing easy installation and
maintenance.
