DARE Electronics, Inc.

Continuously monitor single or three-phase power lines for over or under voltage conditions with DAREs AC voltage sensors, voltage monitors, and voltage sensing relays. DAREs 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 operationUnder-voltage, over-voltage, or voltage band modelsLowest 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 withTime delays on pull-in andor drop-out or with customized voltage-time trip curvesSolid State normally open outputs orRelay 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

Current sensors are designed to monitor the presence or absence of AC or DC current and are available in an assortment of standard & custom models with hermetic or gasket seal models designed to withstand severe environmental conditions. Using internal electronic circuits to detect, monitor or sense AC or DC current, DARE current sensors and monitors can open or close a circuit when a certain pre-set over or under current condition exists or the current falls outside the specified current range. Typical AC & DC current sensor specifications and ratings include:115220440 VAC122848 VDC0 10 Amperes with higher current limits available with the use of an external current transformer Output contacts are available with ratings of:2 amp, 5 amp, 10 amp, or 25 amps SPDT through 4PDT Output contacts can be set to trip for:Under current, over current, or over under (band pass) condition In addition, DARE AC and DC Current Sensors can be:Powered from sensed input lines or from auxiliary AC or DC power
