EMS339 Fuel Optimiser Unit

EMS339 Controller is specifically designed for Telecom applications which minimises Diesel Fuel consumption by delaying the DG start, after a Mains Failure. The DG will start and stop on a demand basis governed by the Room Temperature and Battery requirements. The unit can be setup to minitor the mains directly or detect a mains failure from a digital input. The unit provides 3 outputs for system control or information. Alarms and Warning are shown on the LCD and supplemented by the Alarm output.The unit maintains 4 independent hour meters: Total Operational Hours, Mains Hours, Battery Hours and DG Run Hours.
