Programmable AC Power Sources up to 3000VA

GWInstek APS 700028 November 2017 - GWInstek introduced the new APS-7000 series programmable AC power sources, which includes the models APS-7050 (500VA), APS-7100 (1000VA), APS-7200 (2000VA) and APS-7300 (3000VA). The APS-7000 series features low noise, low THD, and highly stabilized power output that are ideal for the product development and verification. The maximum rated voltage is 0 to 310Vrms, 25.2Arms, 100.8A peak current and the output frequency range is 45 to 500.0Hz.

APS-7000 series are suitable for simulating power grid and conducting inverter output characteristic tests, including synchronized phase and frequency. Reverse current and power detected by APS-7000 series will be displayed in red readings to facilitate test observation. APS-7000 series utilize Simulate mode and Sequence mode to provide a single step or consecutive power changes; and to simulate power grid’s Voltage Abnormality Test and Frequency Abnormality Test.

APS-7000 series comprise nine measurement and test functions (Vrms, Irms, F, Ipk, W, VA, PF, Ipk hold, CF), and provide user interface similar to that of AC Power Meter. APS-7000 series are ideal for the LED industry and standby mode power consumption test. Under the ARB mode, APS-7000 series provide waveforms in seven categories including Sine waveform, Triangle waveform, Staircase waveform(Square wave), Clipped Sinewave, Crest factor waveform, Surge waveform, and Fourier series and 20,000 waveform combinations so as to meet the requirements of simulating abnormal input power waveform test of various industries. Ten Preset settings allow users to store ten sets of data; Power ON Output setting allows Sequence, Simulate, and Program to automatically execute output after the equipment power is on.

To meet the test criteria of line voltage fluctuation often seen in consumer electronics, APS-7000 series feature five methods to cope with special purpose or abnormal voltage, frequency, and phase; ten sets of the Simulate mode simulate power outage, voltage rise, and voltage fall; ten sets of the Sequence mode allow users to define parameters and produce sine wave by editing steps; ten sets of the Program mode can edit AC waveform output and define the ceiling and floor level of measurement items for different DUTs; Ramp Control allows users to set the variation speed for output voltage rise and fall; Surge/Dip Control simulates DUT’s input power producing a Surge or Dip voltage overlapping with output voltage waveform at a specific time. For larger current output applications, voltage drop across the output cables should be avoided. APS-7200/7300 also provide the remote sense function, which senses DUT’s voltage and sends the information back to APS-7200/7300 for program controlled voltage compensation. Therefore, APS-7200/7300 can provide users with very accurate large current measurement applications.

Ethernet Port, on the rear panel, can be used for remote program control; Sync Output Socket provides external 10V sync output; Signal Output Connector provides monitor of Program execution results. APS-7000 series also provide users with Trigger In/Out and Output on/off remote control functions from J1 connector on the rear panel.
