Home | Automatic Mains Failure Units | DKG-225 AMF Unit with Battery Charger



DKG-225, is a low cost AMF controller for 12V-DC gensets, featuring an internal battery charger and 40Amps rated fuel and crank relays. 

It reduces the material cost, panel size and production time in panels where it is used.

Thanks to the DKG-225, automatization of small gensets has become easy and cost effective.


The 1Amp @12V-DC rated battery charger is sufficient for the float charging of the engine start battery.
Internal fuel and crank relays are rated at 40Amps@12V-DC.

The unit supports also current transformer connections allowing detailed power measurements from both mains and genset sides. The standard unit supports 1A and 5A secondary CTs. 

Timers, threshold levels, input and output configurations are digitally programmable. Programs are modified through front panel pushbuttons and do not require an additional unit.
