Voltage Window Comparator – DVW1

R605.70

Single Phase Voltage Window Comparator for monitoring supply voltage between two levels. The unit is ideal for all single phase voltage monitoring applications to protect valuable equipment. With the wide range of delays, the protection is extended to prevent immediate re-starts. Over and under voltage can be set via front panel dials. The latch facility prevents unmonitored fault conditions. Hysteresis is fixed at 5%.

 

Features:

 

  • High resolution analogue microprocessor
  • Front face adjustable over and under voltage levels
  • Monitors own supply
  • 4 Front face selectable delays
  • Optional latch facility
  • Modular 35.5mm DIN rail mountable
  • 10A SPDT output relay
  • LED indication for over and under voltage
  • LED indication for power supply ON
