AMF Controller

Automatic Controller for AMF & Standby Power Systems [with out U/V & O/V Protn.]
Custom-made Micro Controller based products

‘Run Mode’ :

  • Unit can Operate in either ‘Manual’ or ‘Auto’ Modes, by pressing respective Front Panel Keypad provided.
  • When in normal ‘Run mode’ all “Function” & “Value” LEDs are ‘OFF’ [if ‘Auto’ in mode, its LED shall be ON]
  • In either of the Modes, all Functional & related Interlock parameters are inherent, for fail safe operation.

Technical Specifications

DC Supply [working of Unit] 06 VDC to 35 VDC ~ continuously variable [step less]
Choice of Battery Voltages ‘Select’ : 12V or 24V Battery, with indication & supervision of Battery Voltage status.
Battery Under-Voltage Levels> Under-Voltage Levels, for supervision with indication : <8 VDC for 12V Battery .&. <16 VDC for 24V Battery
‘Cranking-Dropout’
dip of Aux. Supply		 Withstands upto 0 VDC ‘Dip’ of Auxiliary Supply [during Cranking] upto 01 second [maximum].
Hence internal batteries / ‘voltage-boosters’ not required.
Maximum Operating Current 40mA [max] at 12V Battery …and…  25mA [max] at 24V Battery.
Typical Operating Current 15mA at 12V Battery  …and…  10mA at 24V Battery, at ‘No-Fault’ condition.
Mains [EB] & Alternator Inputs These TWO Inputs to Unit shall be from: ‘NO’ [Normally-Open], Potential-free Relay Contacts ONLY.
Aux. Alarm & Other Inputs Aux. Inputs to Unit shall ONLY be from Potential-free dry Contacts of Relays, Micro switches, etc..
