1. Summarize
The Power Combination Transmitter, mainly transmit the measured 1-way active power signal, 1-way reactive power signal and 1-way current signal. At the same time, the fourth way can transmit measured three-phase voltage, three-phase current or power factor (chooses one of the three) to isolated output four-way analog signals or output digital signals, with RS485 communication. The power supply could be from the load devices.
The Products meet the standard of GB/T22264.1-2008, GB/T 13978-2008.
