The Instek APS-7050 Programmable Linear AC Power Source, 500VA contains abundant features for the testing and characteristic analysis of power supplies, electronic devices, components and modules. This power source is fully programmable to simulate different power outputs. All parameters and values, as well as measurement results are displayed simultaneously on the 4.3 inch TFT-LCD screen.

The APS-7050 comprises nine measurement functions (Vrms, Irms, F, Ipk, W, VA, PF, Ipk hold, CF), and has a user interface that is similar to an AC Power Meter. The internal circuit has 4 sets of current ranges to improve measurement resolution; it is ideal for the LED industry and standby mode power consumption testing. Under the ARB (function waveform) mode, the APS-7050 provides waveforms, including SINE waveform, triangle waveform, staircase waveform, clipped sinewave, crest factor waveform, surge waveform, and fourier series to meet the requirements of simulating abnormal input power waveform tests in different industries. Ten sets of preset allow users to store ten settings; Power ON Output setting allows Sequence, Simulate, and Program to automatically execute output after the equipment power is on.

The APS-7050 features five methods to cope with special purpose or abnormal voltage, frequency, and phase; ten sets of simulate mode to simulate power outage, voltage rise, and voltage fall; and ten sets of sequence mode to define parameters and produce sine wave by editing steps. Ramp control allows users to set the variation speed for output voltage rise and fall; and surge/dip control simulates DUT's input power, producing a surge or a dip in voltage to overlap with output voltage waveforms at a specific time. There is an ethernet port on the rear panel of the device, which can be used for remote program control; a sync output socket provides external 10V sync output; and a signal output connector monitors program execution results. The APS-7050 can also trigger in/out and output on/off remote control functions from a J1 connector on the rear panel.
