Need an Arbitrary Waveform Power Source? No Problem!

The AC power supply GW Intek GW-APS-1102A is not only in the role as a precision AC/DC power source but also a powerful analyzer, containing abundant features for the testing and characteristic analysis of power supplies, electronic devices, components and modules. Besides providing AC/DC power, APS-1102A also allows free programming of outputs for the simulation of a power source with abnormal variations. The instantaneous interruption, frequency sweeping, voltage sweeping, and arbitrary waveforms of power source can be easily generated in accordance with the test requirements. The output function includes two main modes, AC and AC + DC. Each mode can be combined with any of the four signal sources, internal (INT), external (EXT), internal + external (ADD), and synchronization, to give an ultimate flexibility of power source setting. APS-1102 includes a multi-functional and user-friendly software, which supports the remote control of panel operations, Sequence editing and execution, Arbitrary waveform editing and transfer, and Data logging via USB interface. With capacity of 1kVA power and weighting of 20 lbs, APS-1102A provides powerful test and analysis features all in a comparatively compact and light-weight box. 

Output Modes 

Power output function includes AC and AC+DC main modes. Each mode can be combined with one of the signal sources, including internal, external, internal + external, and external synchronization, to provide a strong tool for the generation of a power source with abnormal variations.

  • Output of Arbitrary Waveforms
    Arbitrary waveforms can be edited on the PC and transferred via USB interface to GW Intek GW-APS-1102A as the internal signal source for power output. 16 sets of waveform memory with 4k words waveform length each are available for arbitrary waveform generation and storage.
  • Amplifier of External Signal
    The APS-1102A can be used as an amplifier for the external signal to generate output power source. When one selects the external signal source mode (AC-EXT or AC+DC-EXT) and connects the external signal to the external signal input/external sync signal input terminal (EXT SIG IN/EXT SYNC IN), APS-1102A generate the power output according to the waveform of the external signal input.
  • Power output synchronization with External Signal
    The externally synchronized oscillation of APS-1102 allows the output power source to be frequency-synchronized with the external signal at TTL level in the frequency range from 40Hz to 500Hz. B.

Measurement Functions

The GW Instek GW-APS-1102A is equipped with the following measurement functions

  • Voltage (RMS, Average DC, Peak)
  • Current (RMS, Average DC, Peak, Peak hold)
  • Power (Effective, Reactive, Apparent)
  • Synchronization frequency (external synchronization)
  • Load power factor
  • Load crest factor
  • Harmonic current (50/60Hz fundamental, up to 40th harmonics)

Sequence Operation Function

In the Sequence Operation programming, DC, sine waves, square waves, and 16 arbitrary waveforms captured via the USB interface can be used as elements for sequence editing. Among the total 255 sequence steps, as maximum capacity, the waveform, level and time duration can be set; constant / keep / sweep can be chosen in each individual step. The GW Instek GW-APS-1102A is also equipped with other functions, such as branching to a specified step during a sequence operation. All the data of start, stop, or hold of sequence operation are saved into the sequence memory to perform the sequence operation automatically.

Inrush Current Measurement and Inrush Current Limiter

An electronic device containing a capacitor type rectifier, an inrush current, which is larger than the rated current of the device, may flow through the power line immediately after the device is turned on. GW Instek GW-APS-1102A, with peak current hold capability, is able to measure this short time inrush current. On the other hand, the large inrush current flows through the power line may cause the voltage drop, so the electronic device should be able to limit this effect to a certain extent. APS-1102A can supply four times as large peak current as the rated current to support this test. The output current can be limited by setting the maximum output current (peak/average current) in advance, so the prototypes can be protected from abnormal current damage during development evaluation. However, to measure the inrush current of a completed product, the peak current limiter should be set at the maximum value to get a correct measurement result.

Harmonic Current Measurement Function

Switching power sources are widely used in both consumer and industrial electrical products in today€™s market. With the capacitor type rectifier, the switching power source has its disadvantages using an input AC source carrying significant amount of harmonic current. When a large amount of harmonic current flows through the power source line, the switching power supply in the device may experience operation faults caused by the voltage distortion, leading to transformer overheat and possibly resulting in a hazardous accident. APS-1102A includes a harmonic current measuring function, which can be performed under AC-INT mode at the fundamental wave setting (panel frequency setting) of either 50 Hz or 60 Hz. Absolute values of harmonic current in RMS and the harmonic to fundamental ratios up to the 40th harmonics ( 2 kHz at 50 Hz fundamental) can be measured and displayed.
