The large colour touch screen provides simple and fast operation for customers, real-time update of display output data and power status, and graphical display makes it more intuitive.

Graphical User Interface AC Programmable Power Supply

Settable ON/OFF Phase angle of Output Waveform

This series of AC power supply can set the ON phase and OFF phase of sinusoidal output waveform, suitable for the output test of switching power supply. Set the ON angle to 90 degrees for surge current testing, the power supply will show the measured value of surge current. Users can set when start to measure the surge current and the duration of the measurement.
