IEC 61009-1 Residual Current Protector Device Action Characteristic Tester
System overview:
The test equipment conforms to the standard requirements of IEC 61009-1:2012, IEC 60898-1:2015, IEC 61008-1:2010, etc.
It is used for automatic verification of the operating characteristics of small leakage circuit breakers, and verifies the safety performance of circuit breakers. The instrument takes ARM-7 high-speed processor as the core, equipped with high-speed true effective value A/D converter, DSS sinusoidal signal generator and power amplifier with mains tracking, the instrument automatically outputs current, and can perform action current, action time etc. test project.
Features:
➢ 24-bit high-speed and high-precision true RMS AD conversion, accurate sampling of operating current and voltage
➢ High-speed processor to accurately sample the action time
➢ Support the standard Modbus-RTU communication protocol
➢ Support quick selection of operating current for conventional products and separate setting of operating current for unconventional products
➢ 32-bit embedded processor, high-speed processing a large amount of communication data
➢ RS232/485 full-rate asynchronous serial communication interface, the maximum baud rate can reach 115200bps
➢ Isolation protection for input and output signals, safe work
➢ Software and hardware watchdog WDT design to ensure system stability
➢ The configuration parameters are stored in the flash memory, which will not be lost when the power is off, and will be stored permanently
➢ Anti-jamming design of software and hardware, can adapt to the occasions with harsh electromagnetic environment
