APS-7000 is a series of programmable linear AC power supply, with the height of 2U and output frequency range is 45~500Hz, , the maximum rated output for APS-7050 is 500VA, 310Vrms, 4.2Arms and APS-7100 is 1000VA, 310Vrms, 8.4Arms. The optional collocation can be extended to the maximum output voltage of 600Vrms and maximum output frequency of 999.9Hz. The APS-7000 series comprises nine measurement and test functions (Vrms, Irms, F, Ipk, W, VA, PF, Ipk hold, CF), and provides user interface similar to that of AC Power Meter. The APS-7000 series, via switching many sets of current levels to increase small current measurement resolution, is ideal for the LED industry and standby mode power consumption test. To meet the test criteria of line voltage fluctuation often seen in consumer electronics, APS-7000 series not only supply a stable source of AC, they also features five methods to cope with special purpose or abnormal voltage, frequency, and phase; ten sets of the Simulate mode simulate power outage, voltage increase, and voltage drop; 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 DUT; 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.

The series is ideal for user to produce high complicated waveform and transient waveform to verify electronic product operation under adverse condition.

APS-7000 series currently involves APS-7050 & APS-7100 as below:

APS-7050 Output Operating Area	APS-7100 Output Operating Area

There are ten sets of Sequence mode and each set has 0~255 steps. The time setting range for each step is 0.01 ~ 99.99 seconds. Combining many sets of steps to edit required waveforms satisfies users’ requirement of highly complicated waveforms.

Sequence waveform

This mode can rapidly produce different simulated input transient waveforms such as power outage; voltage rise and voltage fall etc. for engineers to evaluate the impact on DUT posed by the transient phenomena. For instance, capacitor endurance test.
Power Outage	Voltage Rise	Voltage Fall

Program Mode

This mode allows users to set ceiling and floor specifications to produce PASS/FAIL result after the measurement is done. It can also show test results for each test procedure or only show the last result. There are ten sets of Program mode and each set has 50 sets of memories. Each memory comprises 9 steps. Each Program will perform according to memories sequence, self-defined loops or designated steps to stop.

This mode provides more than 50 different waveforms in 7 major categories to rapidly simulate distorted AC voltage waveforms.
Sine waveform Standard AC Waveform	Triangle waveform Power harmonic output simulation is triangle waveform
Staircase waveform Simulate square waveform and staircase waveform for commercial UPS	Clipped sinewave Simulate grid power supply heavy load waveform
Crest factor waveform Simulate rectified filter current waveform by capacitor input	Surge waveform Simulate grid power supply’s peak over-voltage
Fourier series synthesized waveform   Simulate real output power waveform. Distorted power waveform is produced due to output impedance and non-linear effect such as inductance, capacitance, and parasitic capacitance effect. For example: motor.
