CT and PT
RS485 Serial-Modbus RTU
CT1 (primary current): 1~9999A
CT2 (secondary current): 333mV
PT1 (primary voltage): 100V ~ 500,000V
PT2 (secondary voltage): 100 to 480 V AC (L-L)
This unit uses a RS485 serial port with Modbus RTU protocol to provide a means of remote monitoring and controlling.
Please check the Part 4.2 for the details of setting.
