Product Introduction

       High Current Generator is a test current source used as a low-voltage, high-current power supply for thermal stability and dynamic stability tests of electrical appliances, such as temperature rise tests and tripping of air circuit breakers, contactors, and relays.

       When testing three-phase systems with a Single-Phase High Current Generator, it should be conducted phase by phase;
       Three-Phase High Current Generator is mainly used for testing three-phase electrical products and can also be used for single-phase electrical products. The control schemes for three-phase and single-phase high current generators are the same, except that the three-phase generator outputs three-phase current.
       High Current Generator consists of three parts: transformer, voltage regulator, and controller.

Product Features

       320×240 LCD display, high-speed thermal printer.

       High-precision sensors and high-performance 14-bit AD acquisition chip.

       Full keyboard operation for human-machine dialogue, intelligent workflow.

       Optional Automatic Current Ramp Test, Manual Current Ramp Test, and Impulse Trip Test, flexible and simple operation.

       Real-time display of output current and time results, intuitive and clear.

       Comprehensive overcurrent protection, allowing arbitrary setting of target output current value, current upper limit, and withstand time.

       Zero-return detection function, ensuring tests are conducted only after zero return is confirmed, safe and reliable.

       Step-by-step current ramp algorithm, automatic withstand timing after reaching the target output current, motor automatically returns to zero after timing ends.

       Motor automatically returns to zero and triggers audible and visual alarm when exceeding the set output current upper limit.

       Excellent hardware and software anti-interference design, multiple anti-interference methods, suitable for harsh electromagnetic environments.

       Automatic error diagnosis, easy to identify and resolve issues.

Technical Parameters

       The device capacity is designed for a 5-minute short-time duty cycle. For intermittent operation, the通電時間 should be less than 2.5 minutes, and the工作周期 should be greater than 10 minutes. Specifications and technical parameters are as follows:
