The AT9220A AC/DC withstand voltage tester features a 5-inch colour LCD with touch control and a high-performance 32-bit ARM processor, and is compact, lightweight and easy to operate. Its high-voltage module uses a DA reference, a controllable sine generator, a class AB power amplifier and a 40–600 Hz high-voltage transformer for step-up, with closed-loop control of the output voltage.
The instrument supports AC withstand voltage testing from 0.050 kV to 5.000 kV and DC withstand voltage testing from 0.050 kV to 6.000 kV. Handler (PLC) and RS-232C interfaces allow convenient data communication and remote control from a PC, meeting the requirements of automated testing and improving production efficiency.
