Product Description

The CTF50 transformer is a high-performance 1000A current sensor integrated with a 5A instrument transformer, designed for precise current measurement and monitoring in power distribution systems. It features a single input channel rated for 1000A AC and delivers a standardized 5A output, compatible with meters, relays, and control modules. The device supports direct connection to energy management systems via RS-485 or Modbus interfaces. Operating within 85-265V AC and -25°C to +70°C, it suits harsh industrial environments like utilities, manufacturing, and renewable energy plants. Advantages include ±0.5% accuracy, robust construction for vibration resistance, and easy integration. Limitations include fixed ratio configuration. With IP65 protection, it requires no external power or display, offering reliable performance for medium-voltage networks. Detection range covers 10-1000A with linear response. Compact dimensions (120x80x40mm) ensure space-efficient panel mounting.
