Product Features 



① Smaller size, lighter weight, more aesthetically pleasing, more reliable, easier to operate, and fully functional, making it the ideal replacement product for the power system in the 21st century. 



② Manufactured with the most advanced technology. Pulse train logic array modulation, using high-power IGBT devices, phase fuzzy control, resulting in higher output stability, smaller ripple, and frequency up to 100kHz. 



③ Designed for maintenance-free operation, with main components imported from Germany, the United States, and Japan, durable and resistant to continuous direct short-circuit discharge to ground. 



④ High precision and accurate measurement. The output voltage adjustment uses a single multi-turn potentiometer, with smooth voltage rise and high adjustment precision, and features coarse and fine adjustment functions. The instrument can measure leakage current at both high and low voltage ends. The high-voltage end uses a spherical shielded digital display, resistant to discharge impact. Strong anti-interference performance, suitable for field use. 



⑤ The voltmeter on the control box directly displays the voltage value applied to the load test object. No external voltage divider or current limiting resistor is needed, simplifying wiring and operation. 



⑥ Negative polarity output, zero-start, continuously adjustable, with various protection functions such as overvoltage, overcurrent, return-to-zero, grounding protection, and disconnection protection. Strong automatic protection, safe operation, and all technical indicators are superior to industry standards and similar products. 



⑦ Equipped with a 75% function, greatly facilitating zinc oxide arrester measurements. The control box has a 75% voltage switch function. When the current rises to 1000uA, press the 75% button. The values displayed on the voltmeter and ammeter are the 75% data. After completion, immediately return the boost knob to zero and the fine-tuning voltage knob to zero. Also, immediately switch the 75% button back to the normal position before conducting other tests.
