Single-phase reactive power meter

Detailed Introduction

varmeter

Function and Features:
1. The display magnification, communication address, baud rate, etc. can be set through the buttons on the panel, making it very flexible and convenient to use.
2. Optional analog output, with outputs ranging from 4 to 20mA, 0 to 12 to 20mA, etc.
3. Two optional alarm outputs are available to monitor the upper and lower limits of the measured parameters.
4. Optional RS-485 digital interface, using standard MODBUS-RTU protocol.
5. Optional 2-channel switch input, capable of monitoring the switch status within the system.
6. Digital zeroing and tuning, high precision, and extremely cost-effective.
