Enko - Model AMF 3.1 -Automatic Mains Failure Unit

The unit is designed with high process power for versatile and accurate control of all Gen-Set functions. It controls 3 phase mains and single phase generator voltage and also monitors generator load current.

User can program any of the auxiliary i/o ports for custom applications. The menu offers extensive control for each i/o and all the parameters can be configured via PC, using the ENKO PRO-Link configuration program. All the parameters can also be configured from the front panel controls. SMS messages can be sent, using optional GSM interface module.

Many of the control variables can be displayed as required. The analog sensor characteristics can be adjusted from the menu to fit any kind of sensor. There are altogether 10 i/o ports available, where each one can be independently configured via program menu.

Load power is also measured and can be used with dedicated functions in the menu. Decisions can be made depending on active and/or reactive power of the load. Total accumulated power is also measured and recorded.

AMF3.1 control module is optimized for enhanced applications, where customer demands are high and allows minimal solutions for all genset applications with high reliability.
