GW Instek launches the APS-7000E series the economy version of the APS-7000 programmable AC power source. With the height of 2U, the maximum rated output for APS-7050E is 500VA, 310Vrms, 4.2Arms and APS-7100E is 1000VA, 310Vrms, 8.4Arms. The output frequency range of the series is 45~500Hz. The series is ideal for the test and development of DC power supply devices, consumer electronics, automotive electronics and electronic components.

The APS-7000E series comprises six measurement and test functions (Vrms, Irms, F, Ipk, W, PF), and provides user interface similar to that of AC Power Meter. The APS-7000E 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. Ten sets of Preset allow users to store ten settings.

To meet the test criteria of line voltage fluctuation often seen in consumer electronics, the APS-7000E series not only provides a stable AC power source but also features the Test mode to satisfy special or abnormal voltage and frequency variation demands. Ten sets of the Test mode simulate power outage, voltage rise, and voltage fall. The APS-7000E series that simulates waveforms of city power grid’s transient changes is suitable for verifying electronics products operated under abnormal power source.

The APS-7000E series is the economy version of the APS-7000 series. If communications interface and larger voltage/frequency are required, please refer to the APS-7000 series. The functionality comparison between the APS-7000 series and the APS-7000E series is listed on this NPI.

APS-7100/7100E Output Operating Area
A. SEQUENCE MODE

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
B. 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.

C. SIMULATE MODE

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
D. ARB MODE

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.
E. RAMP CONTROL

Ramp control allows users to set output voltage rise or fall speed which is based on time (1ms) or voltage (1Vrms) unit.
Tup-> 0.1 ~ 999.9ms
Tdn-> 0.1 ~ 999.9ms
Vup-> 0.01 ~ 99.99 Vrms
Vdn-> 0.01 ~ 99.99 Vrms
Mode=Time, Tup=1 msec, VAC=100V, Freq=50Hz, Ramp output=on.
Mode=Voltage, Vdn=2Vrms, VAC=100V, Freq=50Hz, Ramp output=off.

G. T IPEAK, HOLD FUNCTION

T, Ipk Hold sets delay time (1ms~60 seconds) for measurement after the output of Ipeak value and the maximum value will be retrieved. Update will be preceded only if measured value is greater than the original value. Ipk Hold is for measuring transient inrush current as soon as the equipment power is on that is usually done by oscilloscope and current probe. T, Ipk Hold delay time setting can be applied to measure inrush current of sequentially activated DUT.

H. CONTROL PANEL CHARACTERISTICS

There are two control panel modes: Standard mode and Simple mode. Both modes are shown as below. Standard mode combines settings and AC Power Meter measurement window display. Users apply Function key (F1~F3) to select required measurement items. There are nine items for selection. Simple mode shows all measurement items on the display.
