Enko - Model AMF 2.0 -Automatic Mains Failure Units

Full Generator control functions can be implemented through the unit program menu. The unit has a configuration parameter menu which can be accessed from the front panel. All engine parameters can be monitored and full engine protection is provided.

Cranking can be achieved manual or automatic, depending on the selected operation mode. Start of engine is detected automatically and crank relay is controlled accordingly.

The alternator values are also monitored and all values are measured and calculated as True RMS values, avoiding false voltage measurements due to high load harmonic contents, hence ensuring reliable operation. The AC voltage inputs are suitable up to 500Vac.

AMF2.0 is designed to fulfill all the required functions to control the load. Mains is monitored on all three phases and protection limits are programmable through the menu. There are three operation modes which the user can select from. Controller will control the load according to the selected mode.

All the measurement calibration can be made through the program menu and there is no need for any trimmer adjustments. The unit menu is protected with two-stage password, allowing user and experienced technician to reach appropriate menu parts.
