Negative Voltage Sensor
This TASC Systems Negative voltage sensor is designed to measure differential DC voltage for isolated power sources. This sensor is typically used for monitoring DC voltages in positive ground systems (-48-volt battery systems) by TASC Systems monitoring remote terminal units, which use a negative ground source. The sensor ± sense inputs are connected to the power source being monitored and the sensor output is then connected to one of the analog inputs of the TASC RTU using signal ground as the return path. The Differential sensors come in two voltage range configurations: 30 to 60 DCV or 8 to 30 DCV.
