FEATURES

  • Complete control circuit for AMF panels and automatic fire fighting diesel pump panels.

-----------------------------------------------------------------------------------------------------------------

DESCRIPTION

These are based on latest micro-electronic circuits and best of other electronic components and technology to achieve the highest degree of reliability, performance and accuracies. AMF AC unit, together with AMF

 

DC Unit provides the complete control circuit for AMF panel. AMF DC Unit can also be used for automatic control of fire fighting Diesel Engine Pump.

----------------------------------------------------------------------------------------------------------------------------------------------------

AMF AC Unit controls the following functions.

  • Mains Under Voltage Monitor

  • Alternator Voltage Monitor

  • Load Transfer time

  • Idle running time.

AMF DC Unit controls the following functions :

  • Engine starting (with or without delay) 3 Attempts

  • Engine Stopping or LOP (Lubrication Oil Pressure) by-pass time.

Various Model of AMF AC Unit are as under :

  • 3PS (suitable for 3 phase generators with stopping solenoid)

  • 1PS (suitable for 1 phase generators with stopping solenoid)

  • 3PF (suitable for 3 phase generators with fuel solenoid)

  • IPF (suitable for 1 phase generators with fuel solenoid)

Various Models of AMF DC Unit are as under :

  • IS (for instantaneous starting of generator with stopping timer)

  • DS ( for delayed starting of generator with stopping timer)

  • IB (for instantaneous starting of generator with by-pass timer)

  • DB (for delayed starting of generator with by-pass timer)
