Performance characteristics
? AT9220 can provide 5kVAC/20mA withstand voltage, 6kVDC/10mA withstand voltage and insulation resistance test.
? Controllable sine generator: It can be set to work at 50 or 60Hz when AC output, no longer subject to line voltage limit;
? Linear power amplifier: The distortion of the voltage waveform is small, and the control is simple and reliable.
? 40 ~ 600Hz high voltage transformer boost: for the DC and insulation resistance test power supply ripple problem, the test instrument produces 600Hz
? AC power supply, rectified to form a DC voltage as a power supply, ensuring that the DC power supply ripple is much smaller than the previous regulator type old voltage gauge.
? Output voltage closed-loop control: Ensure that the load regulation rate is small and the test data is reliable.
? The AT9220 can independently perform AC withstand voltage test, DC withstand voltage test, and insulation resistance test, and can pass the test.
? Project setting of the trial plan, and multi-item sequence test.
