Description

Core Highlights:

  • Clear Display: Multi-digit LED/LCD display. Highly visible even under strong light, ensuring effortless reading.

  • Precise Measurement: High-precision current transformer (CT) or sensor. Accurately reflects line current (typical range: 0-100A AC, customizable).

  • Wide Range Applicability: Multiple measurement ranges available (e.g., 0-5A, 0-100A AC) to meet diverse application needs.

  • Easy Installation: Standard panel-mount design. Compatible with universal power distribution cabinets, enabling quick and simple wiring.

  • Robust & Reliable: Industrial-grade quality with durable construction. Ensures long-term stable operation in electrical environments.

  • Cost-Effective: Provides a high value-for-money current monitoring solution for power distribution monitoring, equipment maintenance, and energy consumption management.

Frequently asked questions

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.

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.

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.

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.

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.
