SS Power Systems is a well know manufacturers of Automatic Mains Failure Panel including Protection for DG sets. Advance technology is used to manufacture these easy and trouble free AMF Panel.

Basic Operation Cycle

During mains supply, if the supply loads on main fails/cuts, the AMF Panel senses this and starts the Genset. Once the Genset is found running, the load is transferred to Genset supply. When mains resume, the load is transferred back to mains supply and Gensets is stopped. In actual operation various inbuilt timers are used and these are as follows:

• Start Delay or Blackout Timer: Time delay from mains failure to DG Genset starting
• Warm up Timer: Time delay from Genset running to load transfer on DG supply
• Mains Ok Timer: Time delay from mains sensing to load transfer on mains supply
• Cool down Timer: Time delay from load transfer on mains to DG shut down
• Lop Bypass Timer: Time delay during which LOP signal is NOT sensed
• Fault Relay Timer: Maximum time duration for sounding hooter after fault is sensed (If reset key is not pressed)

Advantages:

• Subtech electronic AMF panel design is very simple and easy to operate
• Programming the panel is easy to understand. Simple turning ON and OFF of micro switches can get the desired results
• Diagnose: This mode present in the Panel is very helpful for testing of Control Panel and engine, for commissioning of the Gensets, for routine Preventive Maintenance and fault finding
