HTDP-H Ultra-Low Frequency Insulation Withstand Voltage Test Device Product Features:
◆ Current, voltage, and waveform data are all sampled directly from the high-voltage side, ensuring accurate data;
◆ Overvoltage protection: when the output exceeds the set voltage limit, the instrument will shut down for protection, with an action time of less than 20ms;
◆ Overcurrent protection: designed with dual protection for high and low voltage. The high-voltage side can perform precise shutdown protection according to the set value; when the current on the low-voltage side exceeds the rated current, shutdown protection will be activated, with action times both less than 20ms;
◆ The high-voltage output protection resistor is designed inside the booster, so no external protection resistor is needed;
◆ Due to the adoption of a high-low voltage closed-loop negative feedback control circuit, there is no capacitive rise effect in the output.
◆ Good equivalence: scientific theory and practice have proven that 0.1Hz ultra-low frequency withstand voltage tests have good equivalence with power frequency withstand voltage tests.
◆ Small size: theoretically, the capacity is 1/500 of that at power frequency, so it is small in size and light in weight.
◆ Low destructiveness: 0.1Hz ultra-low frequency withstand voltage tests will not cause significant damage to insulation like DC withstand voltage tests, and harmful polarization charges will not enter the dielectric.
◆ Advanced technology: uses power electronic components, microcomputer control, safe and simple, easy to operate, and reliable data.
