AMF3.4 is a full Automatic Mains Failure unit intended to be used for Mains and Gen-Set control, where high process power is required. The controller can be used with single or three phase mains and generator systems
3 phase mains and 3 phase generator voltages are measured in true RMS and also 3 phase generator load current is measured. Phase sequence and Reverse Power Protection is provided for the Generator. 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. The unit can be programmed from remote distance.
Many of the control variables can be displayed as required on the front panel. There are 3 analog sensor inputs available and characteristics can be adjusted from the menu to fit any type of sensor. There are altogether 13 i/o ports available, among which many can be configured by the user. 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 active/reactive power is also measured and recorded.
The real-time clock allows weekly and/or monthly generator control programs to be made, which can manage periodic test run and /or disabling the generator at certain hours or on specific days. Magnetic pick-up input is available for reliable and accurate measurement and control of engine speed.
