Detecting Very Low DC Current Levels

DS1 – DC Current Sensor in a Compact, One-Piece Design for Detecting Very Low DC Current Levels.

DC-Interlock-DS1

The DS1 DC current switch is smaller than other DC current sensors and simpler to use. It is non-adjustable so the output closes when there is current and opens with there is no current. It uses the same circuit voltage to power the sensor as the circuit being controlled so it is easier to install than other sensors.

The DS1 current sensor can be powered by any DC voltage between 10 and 28 volts, and the solid state “contact” closes with a minimum of 0.75 amps DC through the sensing window. The contact can control a DC load up to one amp, up to 30 VDC.
