Voltage Sense Boards (VSB)

The HDS Voltage Sense Board (VSB) consists of a full-featured, isolation amplifier that measures voltage readings up to 1000V DC, and provides an analog 0-5V signal output. The VSB provides isolation between signal and power for safe operation.

Perfect for EV, HEV, PHEV, and Testing applications, the VSB can be used as a primary or secondary voltage sense, auxiliary circuit/contactor check, or control system input. Options include multiple input voltages, power supply voltages, and output voltage scaling. AC and DC options are also available.
