The PS19 series digital power meter has a high-light LED or LCD, and it follows the communication protocol of Modbus-RTU.This product is designed to measure single-phase and three-phase active power or reactive power in low voltage power distribution system. The transformation ratio is programmable, and some other functions can be expanded including digital input, relay output, analog output, communication function, etc. In addition, it has different mounting dimensions, and can take the place of analog power meter directly.
