PZ19 Series Digital Voltmeter

The PZ19 series digital voltmeter is suitable for single-phase and three-phase voltage measurement in low voltage power distribution system. It has a programmable transformation ratio, and some excellent functions can be expanded, such as digital input, relay output, analog output, communication function, etc. Meanwhile, this product contains many installation sizes.

This product is equipped with a high-light LED or LCD, and the communication protocol is Modbus-RTU. Based on these properties, it can fully replace conventional analog voltmeter.
