Comprehensive test and measurement service provider-Shenzhen Weike Electronic Technology Co.
TH9302 series AC/DC Withstand Voltage and Insulation Tester is a newly developed instrument with high cost-effective and simple operation by Tonghui Electronics.
The principle structure of the instrument: the current module is a DA reference, controllable sinusoidal generator, class AB amplifier, output current closed-loop control DA reference: to ensure that the amplitude of the output voltage can be controlled controllable sinusoidal generator: in the AC output can be set to work in the 50Hz, 60Hz, no longer subject to the limitations of the line voltage Line Power Amplifier: the voltage waveform of the distortion of a small degree of simplicity, simple control, high reliability of the anti-impact capability
All series are equipped with HANDLER, RS-232C interface, to adapt to a variety of different needs of high security and reliability of the automatic test system

A. Rear output holes to support contact checks (CK)
For the high-intensity test, due to the internal breakage of the test lead, poor contact of the test tooling, etc. caused by the test withstand voltage, insulation misjudgment failed, TH9302C/TH9302D two models in the rear panel of the instrument to increase the high-voltage test end with the CK function, to ensure that the instrument test results of the validity and correctness of the instrument can be avoided due to the loss of the test accessory and tooling to the customer brought about by the misjudgement.
B. Optocoupler isolated relay output HANDLER, directly connected to the PLC, without conversion circuitry
