FAQ
Q: I bought a three-phase four-wire meter, can it be wired as a three-phase three-wire?
A: Yes, press the key to set the meter to three-phase three-wire mode.
Q: What is the difference between ordinary secondary access and -CT (model external transformer)?
A: Ordinary secondary meter could access the ratio XXX/5(1)A of the CTs which could be actual current on-site, the -CT model comes with an external transformer will be convenient for installation(It cannot be disassembled, otherwise it will burn the meter). There are CTs available on site to facilitate with No stitch removal.
Q: What are 3*100V,3*57.7/100V,3*380V,3*220/380V?
A:3*100V, 3*57.7/100V are used for high voltage, used in conjunction with voltage transformers, where 3*100V represents 3P3W,3*57.7V/100V represents 3P4W; 3*380V, 3*220V/380V are used for low voltage, direct voltage input, among them3*380V represents 3P3W, 3*220V/380V represents 3P4W.
Q: Can this meter communicate with PLC?
A: Yes, only need PLC to support RS485 interface, Modbus RTU, or DL/T645 protocol.
