General Information

This automatic high-current generator is designed for temperature-rise testing and high-current output applications. It combines an energy-efficient high-capacity voltage regulator with a high-permeability core transformer, providing powerful current output in a compact and lightweight design.

The system is suitable for performance verification and temperature-rise tests of thermal relays, motor protection devices, contactors, air circuit breakers, switchgear, circuit breakers, protection panels, busbars and power cables.

To accommodate different testing environments, the equipment is offered in both integrated and split configurations, providing greater flexibility for laboratory testing and on-site commissioning.

Advantage

Clear Digital Display: Real-time readings of current, voltage and temperature-related parameters are shown on the digital meters, making test monitoring and data recording more convenient.
Accurate Test Results: High measurement accuracy helps maintain dependable readings and supports reliable evaluation of test performance.
Adjustable Protection Settings: Over-current protection thresholds and current timing values can be digitally configured to provide precise and responsive safety control.
Flexible Testing Modes: Choose between manual control and automatic operation according to different testing procedures and working conditions.
Automatic Test Documentation: After the test is completed, the system can generate test curves and formatted test reports automatically, simplifying data analysis and record keeping.
