DC Voltage Sensors

DC voltage sensors monitor input voltages ranging from 3 to 500 volts DC with a trip point accuracy of up to 1% in airborne, military and ground power applications. Using internal electronic circuits to detect, monitor and/or sense DC voltage, DARE DC voltage sensors, monitors, and voltage sensing relays can open or close a circuit when a certain pre-set over or under voltage condition exists or the DC voltage falls outside the specified voltage band window.

The most common DC voltage sensors are designed to monitor 28 VDC and voltage transients per MIL-STD-704, but DARE’s DC voltage sensors can be highly customized for a given application.

DARE DC Voltage Sensors, Voltage Monitors, and Voltage Sensing Relays are available in:

Under-voltage, over-voltage, or voltage band models
Hermetic or gasket seal models designed for demanding environmental conditions

In addition, DARE DC 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 DC 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.
