Continuously monitor single or three-phase power lines for over or under voltage conditions with DARE’s AC voltage sensors, voltage monitors, and voltage sensing relays. DARE’s complete line of AC Voltage Sensors will protect system equipment and circuitry from voltage that is hazardous or unsuitable for operation. Whether in an airborne, ground support, military, or other high reliability application, DARE AC Voltage Sensors can be used to monitor for an under-voltage or over-voltage condition or a voltage window. In the event the voltage sensor detects an undesirable voltage condition, the output of the voltage sensor can be used to activate alarms, shed loads, or shutdown systems.
DARE AC Voltage Sensors, Voltage Monitors, and Voltage Sensing Relays are available in:
Single or three phase AC voltage sensing models (Delta or Wye)
50 Hz, 60 Hz, or 400 Hz operation
Under-voltage, over-voltage, or voltage band models
Lowest phase, highest phase, or three phase averaging
In addition, DARE AC Voltage Sensors, Voltage Monitors, and Voltage Sensing Relays can be:
Powered from sensing input lines or from separate AC or DC supply
And, are available with
Time delays on pull-in and/or drop-out or with customized voltage-time trip curves
Solid State normally open outputs or
Relay outputs in SPDT, DPDT, 3PDT, or 4PDT configurations and contact ratings of 2, 5, 10 or 25 Amps
DARE AC Voltage Sensors come in wide variety of finishes, enclosures, connectors, and mounting arrangements and custom configurations are available. The table below describes just some of the various types of voltage sensors available.
