Damped Oscillatory Wave Simulator SWCS-931SD

FEATURES

This unit generates a defined damped oscillatory waveform over a range of 100V to 1500V and applies it to the device under test to check for its surge withstand capability
A semiconductor switch is employed, offering more reliability and energy-saving feature than conventional unit with a mechanical switch.
A wide range of repetition over 0.4Hz to 400Hz
Push button selection for output impedance and coupling capacitance from 50 ohm to 200 ohm at a step of 10 ohm and 0 (short), 470pF and 100pF, respectively. This feature eliminates the need for the operator to touch "HOT" line, offering easy and safe operation.
