AMF 4.0
Automatic Mains Failure Units - AMF Series

Friendly user interface with analog bar graph displays...

AMF4.0 controller includes two analog bar-graph displays to indicate direct readings from engine temperature and oil pressure gauges. AMF4.0 offers flexible control of load power, fed from mains and generator bus-bars. 

AMF4.0 Automatic Mains Failure (AMF) control module from ENKO offers flexible management of Load and Diesel Generator functions. The MCB and GCB relays can be controlled efficiently, allowing minimum load break, with single Mains/Gen-Set applications.  The controller offers 5 digital displays for monitoring system values.

AMF4.0 Automatic Mains Failure (AMF) control module from ENKO offers flexible management of Load and Diesel Generator functions. The MCB and GCB relays can be controlled efficiently, allowing minimum load break, with single Mains/Gen-Set applications. 

The controller offers 5 digital displays for monitoring system values. All voltages and currents are measured as True RMS values, with better than 1% full scale accuracy. 

All three phase voltages of mains and generator side are measured as well as the load phase currents. This allows optimum control of load supply for safe operation. The illuminated mimic diagram allows easy monitoring and function controls on the front panel. 

All system parameters can be configured through an extensive menu. All the I/O ports can be configured and set to match the required application characteristics and all measuring analog inputs can be calibrated, using the system menu. Preset temperature and pressure gauge characteristics can also be selected direct from the menu. 

The controller also includes a “Remote Start” input so that it can be interfaced with other control systems. Remote start characteristics can also be set through the system menu.
