AC detection unit KW-PM3A

Product Description

First, an overview
Used for monitoring the AC input voltage, current, AC switch, lightning protection status; the first and two input voltage monitoring;
AC contactor control, AC switch status, through the RS485 data transmission to the next bit machine.
Two, basic functions:
The measurement of two phase AC input voltage, current and state of AC contactor.
The information will be transmitted through the RS485 serial interface to detect the main monitoring, monitoring and management as the main processing and fault alarm system for power supply.
The automatic two-way AC input automatic switching according to the AC input voltage measurement; to achieve two-way exchanges and mutual standby power supply.
The state provides fault detection lightning protector and 5 AC switch tripping state.
The voltage measurement is directly connected, 50A/5A current transformer is measured by current measurement.
