Four Quadrant Battery supply simulator

The APS xxD series are equipped with a four-quadrant bipolar amplifier, which is capable of generating voltage dips, short interruptions and multiple voltage variations phenomenon and simulating various voltage variation phenomenon tested and obtained on wiring harness. It can be used as battery supply simulation and DC voltage source. During testing in test lab, APS xxD series can replace vehicle battery. Pulse 2b, Pulse 4, sine wave noise and other complicated voltage variation tests can be conducted by APS xxD series simulator, which is greatly suitable for conductive transient tests in accordance with standard ISO 7637/16750. It can simulate multiple battery supply waveforms as per international standards and multiple automotive manufacture standards. Meanwhile, as a powerful DC source, it can supply power for DUT during automotive transient pulse test, which covers all four supply voltage categories (48 V, 42 V, 24 V and 12 V).

Naming Rules:

*） For some of the devices under test (e.g. motor equipment, exhaust fans, wipers, air conditioners, etc.) or DUTs with large capacitive storage accessories, there is a large amount of inrush current. This inrush current is 3-10 times of normal current or even greater. If customers can’t decide inrush current value, our company’s CTM series current test modules can be used to test the working current value, so that you can choose a more appropriate APS series of products.
