Auto Mains Failure Relay

Our expertise enables us to offer Auto Mains Failure Relay With Engine Protection. It is specifically designed for controlling emergency and standby power systems. The range integrates the functions of engine start / stop relay, engine and alternator supervision and annunciator. Our products are offered with MMI in the form of a keypad and a LCD display. Owing to the engine start / stop relay element, during power failure, the engine stops automatically. It also helps in interlocking of mains and DG Circuit Breakers. The range also enables the delayed supervision of oil pressure switch. Some other features of our range are:

 

  • Micro controller technology
  • Wide range of auxiliary supply: 7 V to 35 Vdc
  • With stands a dip to 0V of auxiliary supply for 1 second
  • Flush mounting
  • Alphanumeric LCD display with keypad for easy of operation
  • Display and supervision of D.G voltages for UV, OV
  • Display and supervision of mains & D.G frequency
  • Continuous supervision of mains & D.G breaker status - ensures human / equipment safety
  • Internal interlock for Mains & D.G. breaker for fail safe operation
  • Indication of CB status
  • Wide array of time circuits for start delay, stop delay, mains restoration, recoolingetc
  • Serial Communication (OPTIONAL)
  • Ignition ON input
  • Remote starting and stopping facilities
  • Measuring of different mains and generator parameters
  • True RMS measurement of mains & D.G. voltage
  • Ten internal fault annunciation for start failure, over speed, low battery, stop failure etc
  • Four spare terminals for connecting external fault signals
  • Display and supervision of battery voltage
  • Isolated inputs and outputs
  • Parameter setting from front panel keypad
  • Periodic test feature
  • Seven modes: Automatic, Remote, Manual, Offline, Test , Edit Parameters and Default Mode
  • Over speed indication / shutdown
  • DG starting process supervision

 

Engine Control Relay Type

Engine Control Relay Type

Introduction And Application
AMR1 has been designed for the control of emergency and standby power systems. It integrates the functions of engine start / stop relay, engine and alternator supervision and annunciator. The relay has a user friendly MMI in the form of a keypad and a LCD display. The engine start / stop relay element allows the automatic starting of relay when power fails, automatic stopping of the engine when mains return and also the control and interlocking of mains and DG Circuit Breakers. It also includes delayed supervision of oil pressure switch.
