It serves as a "3C" certification test equipment for low-voltage switchgear and electrical appliance manufacturers. The device utilizes a high-speed microcontroller design, supports manual, automatic, and programmable modes, features an LCD display and touch key interface, and offers advantages such as ease of operation, stable and reliable performance, and a high degree of automation.

Product Features

☆、 Manual/Automatic/Programmable modes; In manual mode, the impulse voltage is adjusted manually via a knob. In automatic mode, the impulse voltage is adjusted automatically by the system. In programmable mode, the impulse voltage is controlled automatically via computer.

☆、 Automatic and programmable modes include an automatic constant voltage system for finer control of output impulse voltage, unaffected by interval time.

☆、 Programmable function provides a 485 communication interface and protocol, allowing the setup of a programmable test system to control impulse voltage and various parameters via computer or programmable network (programmable triggering).

☆、 Supports batch combination testing via computer programmable software, such as 2KV 3 times, 4KV 3 times, 6KV 3 times, -2KV 3 times, -4KV 3 times, -6KV 3 times, etc., with up to 50 combinations. It feeds back test results like breakdown count and breakdown voltage to the computer, which displays the results graphically for intuitive judgment.

☆、 Allows printing test reports via computer, displaying test data such as impulse peak voltage, count, and interval time.

☆、 Automatic test result judgment function, which determines pass/fail based on the magnitude and decay of the impulse current generated during testing.

☆、 Provides an impulse voltage divider interface for oscilloscope tracking of output voltage waveform and monitoring of output voltage.

☆、 12864 LCD display, simultaneously showing DC voltage, impulse voltage, interval time, and impulse count.

☆、 Touch keys, microcomputer control, Chinese panel, optional Chinese/English panel and program menu for export convenience.

☆、 Positive and negative polarity designed with dual systems of positive high-voltage source and negative high-voltage source, offering more stable output, higher voltage, and higher efficiency.

☆、 Innovative full-range calibration process for better accuracy across the entire range.

☆、 Built-in multiple parameter standard calibration programs, allowing error correction during calibration.

☆、 Dual output: DC and impulse.
