Instructions for using the 2000A high current generator:
When conducting high current tests, correctly connect the working circuit according to the circuit diagram of this product. Based on the output current magnitude, select the appropriate position for the high and low range switch. First, return the voltage regulator to zero, then press the start test button (green). At this point, hold the handle of the voltage regulator and slowly rotate the handwheel clockwise while observing the ammeter until the desired current value is reached. After the test reaches the set value, immediately rotate the handwheel counterclockwise back to zero, press the stop button, and cut off the power supply.
Features:
◆ Date, voltage, current, and time are displayed simultaneously on a blue 5.7-inch large LCD screen with backlight, providing clear and intuitive readings. It displays voltage, current, time, etc., and has various data setting functions, along with a high-speed thermal printer.
◆ The start/stop conditions of the time relay can be arbitrarily set, with a settable time range from 1 second to 9999 seconds.
◆ High-precision sensor and high-performance 14-bit AD acquisition chip.
◆ Touch-sensitive panel button operation; all functions can be set via buttons, enhancing product safety, reliability, and intelligent operation throughout the process.
◆ Optional automatic current rise test, manual current rise test, and impact quick-break test, offering flexible and simple operation.
◆ Real-time display of output current and time results, providing clear and intuitive visualization.
◆ Comprehensive overcurrent protection, with arbitrary setting of target output current value, current upper limit, and current withstand time.
◆ Equipped with grounding detection and return-to-zero detection functions; the test can only be conducted after grounding and return-to-zero are confirmed, ensuring safety and reliability.
◆ Approach-type current rise algorithm; after reaching the set target output current, automatic current withstand timing begins, and the motor automatically returns to zero after timing ends.
◆ If the output current exceeds the set upper limit, the motor automatically returns to zero and an audible and visual alarm is triggered.
◆ Combines hardware and software anti-interference technologies, ensuring stable performance, strong anti-interference capability, and adaptability to harsh electromagnetic environments.
◆ Automatic error diagnosis, making it easy to detect and resolve issues.
◆ Optional remote communication, door interlock alarm light and bell, and open-circuit voltage calibration interface, etc.
◆ On startup, the company name and other information are displayed, which is beneficial for brand promotion and publicity.
◆ Compact size, light weight, reasonable structure, reliable and durable.
Instrument Features:
1. It is a low-voltage, high-current dry-type transformer, suitable for current rise and continuous load tests of switches, current transformers, or other electrical equipment at a frequency of 50Hz.
2. It adopts an integrated structure, with high output voltage and strong load capacity. It is equipped with a current transformer to conveniently monitor the test current. (For models above 4000A, a split structure can be adopted.)
Technical Parameters:
This equipment is designed for a short-time duty cycle of 3 minutes. If used for intermittent operation, the energization time should be less than 2.5 minutes, and the duty cycle should be greater than 10 minutes. Its specifications
