ControllerController (DCSC)
La Marche’s DC System Controller (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 I/O Interface Module
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).

EnclosuresEnclosure Information
La Marche Manufacturing offers Complete Power Systems; including Battery Chargers, Rectifiers, Converters, Inverters, Batteries and Distribution in Indoor and Outdoor Cabinets. La Marche Power Systems are available in multiple arrangements in order to meet different applications’ specific requirements. Cabinets are available in NEMA 1, NEMA 3(R), NEMA 4(X), NEMA 12 and IP ratings.
Different NEMA ratings provide different levels of protection against environmental conditions as described below and in NEMA Standards Publication 250-2003, “Enclosures for Electrical Equipment (1000 Volts Maximum)”.
NEMA 1 is a basic general purpose indoor enclosure designed to protect people from incidental contact with the components inside as well as a degree of protection against solid objects.
NEMA 3R is a basic outdoor enclosure designed to protect the enclosed equipment against rain. It provides protection against falling dirt, rain, sleet and snow.
NEMA 4 is a watertight and dust tight enclosure. It provides protection against falling dirt, windblown dust, rain, sleet, snow, splashing water and hose directed water. NEMA 4(X) provides protection against corrosion.
NEMA 12 is a dust tight and drip tight enclosure intended for indoor use. It provides protection against falling dirt, circulating dust, lint, fibers, and dripping water.
*NEMA 3R, 4 and 12 also provide protection for people against incidental contact with internal components.
