The smartest approach to provide uninterrupted power for critical applications is to transfer sources between the

load. ATeS (Automatic Transfer Switch) is designed with automatic start/stop DG operation to ease the transfer

between primary source to alternate source for providing uninterrupted power supply.


Switch to ATeS:

  • Elmeasure ATeS is a perfect dual power transfer switch ranging from 63A-630A, to ensure smooth and high speed load transfer in the event of power outage or disturbances in the power supply.
  • ATeS is incorporated with Fire Alarm/External fault trip and plays a pivotal role in providing maximum immunity to the electrical system from fire risk/faults.
  • ATeS is systematized with time delays (timers) to prolong the stability of power source during automatic switching of sources in the case of blackout or loss of power.
  • ATeS facilitates easy installation and ensures reliable performance.


Allow users to:

  • Protection against undervoltage/overvoltage, under frequency/over frequency and phase missing
  • Monitor and indicate source healthiness & output for both Sources
  • To select a wide range of motor operating voltage from 150VAC – 285V AC (high bandwidth voltage)
  • Eliminate the need for external AMF Controller due to the availability of in built Microprocessor controller with DG start/stop option
  • Provide the safest changeover during the failure of a primary source
  • Monitor the real time system voltage and frequency for EB/DG
  • Facilitate easy installation and simplified wiring connections
  • Retain safe, reliable and maintenance free operation
