Function & Advantage
Graphical User Interface
The large color touch screen provides simple and fast oper ation for customers, real-time update of display output data and power status, and graphical display makes it more intuitive.
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.
Slew Rate Setting For Voltage and Frequency
This series AC power supply let users set the slew rate of voltage and frequency, in such application in order to reduce the inrush current during motor or compressor startup.
Triac Dimmer Function
This series AC power supply built-in triac dimmer function, which is used to do dimming and speed regulating test for lamp or electric motor to ensure the products work well both in R&D and production testing.
Power Line Disturbance Simulation
This series AC power supply provides powerful function to simulate all kinds of power line disturbance conditions such as cycle dropout, transient spike, brown out and etc. This feature make this series AC power supply ideal for R&D labs, universities and certification labs.
