Product Overview
The GPT-9901A is an AC withstand voltage tester in GW-INSTEK's GPT-9900 series, designed to perform AC withstand tests only. The unit is used for controlled AC voltage test procedures where specified AC voltage levels must be applied and monitored.Technical Overview
The GPT-9901A provides an AC output from 0.050 kV to 5.000 kV with 2 V resolution. The maximum rated load is 500 VA (5 kV / 100 mA) and the maximum rated current in the high range is 100 mA. The output signal is a sinusoidal wave, and the frequency can be selected between 50 Hz and 60 Hz. The unit has built-in voltmeter and current measurement with specified accuracy and regulation.
Usage and Operation
As an AC withstand voltage tester, the GPT-9901A is used for controlled AC current/voltage test sequences where voltage up to 5.000 kV needs to be set and applied, the resulting current measured, and arc detection and comparator window monitored. The unit has ramp time and timer options to control test sequences, as well as a sweep function according to the manufacturer's specifications.
