Functions & Advantages
Graphical User
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.
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.
High Output Crest Factor
This series AC power supply deliver up to 5~6 times of peak current from its RMS current, so it is suitable for testing switching power supplies and motor with high inrush current issue.
Power Sweep Function
This series AC power supply can test the efficiency of switching power supply and capturing the voltage, current, power and frequency at the maximum power operating point, the measurements will be displayed at the end of the sweep.
Triac Dimmer Function
Power Line Disturbance Simulation
List Mode
Step Mode
Pulse Mode
Voltage Sag/Voltage Spikes
Test Mode
The test mode compares measurement values against a user-defined set of measurement limits and shows a PASS or FAIL result in one or more measurement are out of range. The user can set when start of the measurement and duration of the test.
File Save and Recall Via the USB Interface
The user can save the screenshot via the USB interface in the front panel. The user can import a CSV file via the USB interface to generate waveform output.
Parallel/Series/3-Phase Mode
This series AC power source can be used in parallel or series to provide more power, the maximum current up to 184A and the voltage up to 600V. In 3-phase mode, the Master unit is always phase A, Slave 1 is always phase B and Slave 2 is always phase C. The phase difference between phase A and B is always 120°and between phase A and C is always 240°. The output voltage of phase B and C will be set to the same setting as that for phase A (Master) if the Voltage Mode is set to COM. Or if the Voltage Mode is set to Multi, phase B and C output voltage can be set individually to simulate 3-phase unbalance system. The output of 3-Phase system can be connected for three-phase, four wire (Delta configuration) loads or for three-phase, five wire (Wye configuration) according to the application requirement.
External Control Function
By selecting Analog I/O card to achieve below function:
Amplifier Mode
In Amplfier mode, the power source acts as a power amplfier, taking a low-level analog signal and amplifying it by a fixed amount of gain
Professional Version
Programmable Output Impedance Function
The low output impedance and low voltage harmonics of this series power supply make it ideal for IEC61000-3-2 standard testing. A current feedback control circuit makes the output voltage changed with load. This feature is suitable for IEC61000-3-3 Flicker tests. The user can set the resistance and inductance value according to the test requirement.
Harmonic/inter-harmonic Generation Simulation and Measurement Function
Support creating waveforms made up of a series of harmonics frequencies, amplitudes and phase shifts, up to 40 orders harmonics of 50Hz or 60Hz. The harmonics measurement function measures total harmonic distortion (THD), DC voltage and current and fundamental voltage and current for output settings of 50Hz or 60Hz.The measurement of 2~40 orders can be displayed in absolute values or in percent of the fundamental, the harmonics measurement will be displayed with a graphical representation.
