Relay Test Kit with Three Items for Protection Testing

Developed based on the DL/T624-2010 standard Technical Conditions for Microcomputer Test Equipment of Relay Protection, the XHJB634 Microcomputer Relay Protection Calibrator leverages microelectronic technology to achieve miniaturization. Its R&D is based on a comprehensive summary and optimization of the strengths and weaknesses of existing peer products.

The core of the main unit consists of a high-performance industrial control computer and a high-speed digital signal processor, with a 16-bit DAC module, 8.4-inch LCD display and embedded keyboard as standard configurations. It offers dual operation modes (standalone and laptop connection), with the outstanding characteristics of powerful operational capabilities, compact structure and high testing precision.
