電圧試験装置。[Claim for Utility Model Registration] A pulse absorbing capacitor is connected to the output end of a common high voltage generation circuit, and multiple branch paths and each branch to which a high voltage is applied via a resistor to each photocoupler under test. The test device is equipped with individual measurement/judgment sections that measure the insulation current of the circuit and judge the withstand voltage of the photocoupler under test, and each of the measurement/judgment sections is powered by an isolated DC/DC converter, and the photocoupler 1. A photocoupler withstand voltage test device, characterized in that it outputs a judgment signal based on
