Zhongxu voltage sensors feature >500-megohm insulation resistance

The HVC-020 and HVC-25H voltage sensors feature an insulation resistance >500 megohms. The devices measure ac, dc and impulse voltage making them suitable for use in automatic control systems, overvoltage protection, variable speed motor, power source, invert welder, and energy management.

The devices are members of the HVC series and are based on Hall-effect sensors. They have a response time of 20?s and are rated for operation at ±15Vdc, with <±5 percent fluctuation, at a temperature range of -40°C to 85°C.

The HVC-020 offers a 5mA nominal input current, 20mA output current and 2:5 turns ratio. The HVC-25H has a nominal input current of 10mA and an output of 25mA, as well as 1:4 turns ratio.
