Portable Intelligent AC/DC Withstand Voltage Tester

The AC/DC withstand voltage test device is developed based on conventional power frequency withstand voltage test equipment. It replaces manual operation with intelligent control, offering higher test efficiency and a greater degree of automation, making it a new generation of power frequency withstand voltage testing products.

The AC/DC withstand voltage test device is designed according to the latest industry test standards. It is safe, reliable, powerful, user-friendly, and easy to maintain. It is mainly used for insulation strength tests under specified voltages for various electrical products, components, and insulating materials. It evaluates the insulation level of products, detects insulation defects, and measures overvoltage tolerance. It is essential for power operation departments, electrical equipment manufacturers, metallurgical and coal mining industries, electrified railway sectors, research institutions, and universities that require withstand voltage test equipment.

Features of the AC/DC withstand voltage test device:

Voltage, current, time, status information, and prompts are displayed on a 4.7-inch large LCD screen, ensuring clear and intuitive readability;

Fully Chinese interface, simple and straightforward operation, adaptable to various application scenarios;

Touch-sensitive button operation, all functions can be set via buttons, enhancing safety and reliability;

Fully digital calibration method, eliminating outdated potentiometer adjustments, making field use extremely convenient and precision easy to control (this feature is password protected);

Direct button setting of test transformer ratio (this feature is password protected), allowing flexible application when connecting to testers of different voltage levels, truly enabling one control unit to pair with multiple transformers;

Status reminder function, fully Chinese guided operation, enabling proficient control even without a manual;

During testing, a flashing high-voltage symbol appears on the screen, constantly reminding operators to pay attention to safety;

Test result display function, automatically judging test results (pass or fail), and reliably recording overcurrent, flashover, or breakdown voltage;

Audible alarm for test results; the device emits different alarm sounds for pass or fail, allowing operators to identify results directly from the sound;

Pause function; in automatic control mode, this allows pausing voltage increase or decrease at any point, with flexible pause duration for observing the test sample;

Automatic timing function; in automatic control mode, when voltage automatically rises to the set value, the device starts timing automatically. When the time elapses, it displays the result and returns to zero automatically;

Manual timing function; in manual control mode, the timer can be started manually. When the withstand time ends, the device returns to zero automatically (only available in desktop models);

Manual control mode, similar to traditional electric voltage increase/decrease, with buttons controlling rise/fall, automatic upper/lower limit judgment, and overvoltage protection;

Intelligent voltage rise speed control; when voltage reaches 80% of the target, the rise speed slows automatically, and further slows at 90%;

Combines hardware and software anti-interference technologies, ensuring stable performance and strong anti-interference capability.
