Automatic residual current protection tester

1、 Product Overview:

The residual current action characteristic tester developed by our company is suitable for automatic detection of residual current action characteristics of small, plastic shell residual current circuit breakers. The instrument is based on the ARM-7 high-speed processor, equipped with a high-speed true effective value A/D converter, a DSS sine signal generator with mains tracking, and a power amplifier. The instrument automatically outputs current, which can be used by residual current circuit breaker manufacturers or relevant quality inspection departments to comprehensively measure and identify the leakage action current and leakage tripping time of residual current circuit breakers;
