Power Frequency Withstand Voltage Test Device




Supply Power Frequency Withstand Voltage Test Device Product Features:



1. LCD display, high-speed thermal printer.



2. Four measurement channels: high voltage, high current, low voltage, low current, with high-precision sensors and high-performance 14-bit AD acquisition chip.



3. Full keyboard operation for human-machine interaction, intelligent throughout the process, with both automatic and manual modes.



4. Real-time display of high voltage, high current, low voltage, low current, time, and withstand voltage result, clear and intuitive.



5. Comprehensive overvoltage and overcurrent protection, with arbitrary setting of output voltage, high voltage current limit, low voltage current limit, and timing duration.



6. Zero-return detection function; test can only be performed after confirming zero return, ensuring safety and reliability.



7. Insulation resistance test function, directly reflecting the insulation strength of the tested object.



8. Approach-type voltage regulation algorithm; after reaching the set voltage, automatic withstand voltage timing starts, and after timing ends, voltage automatically decreases to zero.



9. When the set high voltage current or low voltage current is exceeded, the voltage output is automatically cut off, voltage decreases to zero, and an audible and visual alarm is triggered. 10. Sophisticated software and hardware anti-interference design, multiple anti-interference measures, suitable for harsh electromagnetic environments.



10. Automatic error diagnosis, making it easy to identify and solve problems.



11. Optional wireless remote control function, remote communication, door interlock alarm light and bell, external divider calibration interface, etc.

   Working Principle:



1. The high-voltage test transformer is a single-phase transformer with connection group label II. The working process of a single high-voltage test transformer: AC 220V voltage is connected to the power control box (console), and through the auto-transformer inside the control box, 0~200V is adjusted to the primary winding of the test transformer. According to the principle of electromagnetic induction, the required high voltage for testing can be obtained from the high-voltage winding of the test transformer. &nb
