Wiring diagram：
CT ratio can be set via front-panel buttons; calibration requires a standard current source or PC software (with RS485-to-USB adapter), following IEC procedures. The recommended cycle is 12-24 months.
It holds CE, UL, and RoHS certifications, complying with IEC 61326-1 (EMC) and IP20 protection standards. It has overload protection (1.2x long-term, 10x short-term) and anti-interference design for harsh industrial conditions.
Yes, it provides 4-20mA DC/0-10V DC standard analog output and optional Modbus RTU (RS485) communication, seamlessly compatible with Siemens, Schneider, ABB PLC/DCS systems.
Yes, it supports universal AC/DC measurement (e.g., AC 0-100A, DC 0-50A) and wide power supply (AC 85-265V/DC 24V), compatible with global industrial power systems.
It supports direct input (AC/DC 0-5A) for small-current circuits and CT input (extensible to 0-1000A via 5A secondary CT) for large-current scenarios. The CT ratio (e.g., 50/5A, 200/5A) can be set via panel buttons, no need to replace the meter.
