The APS xxxxDSR series is equipped with a four quadrant bipolar amplifier, which simulates various voltage changes on the wiring harness and can generate voltage drops, short-term interruptions, and other voltage changes. The output internal resistance can be adjusted. Built in signal source, users can edit and output any wave through PC software. It can also be used as a battery powered analog and DC voltage source. During laboratory testing, APS xxxxDSR replaced the vehicle battery, generating Pulse 2b, Pulse 4, sine wave noise, and other complex voltage variation waveforms. Very suitable for ISO 7637/16750 conduction transient testing. At the same time, the APS xxxxDSR series complies with numerous international/national standards and automotive manufacturer standards. As a powerful DC power supply, it supports 12V, 24V, 42V, 24V, and 48V system automotive testing.

The naming convention for instruments is as follows, using APS 80I100DSR as an example:
APS: Power supply voltage change simulator;
80: Maximum voltage 80V; 40:40V, 60:60V;
I: The level representing negative voltage, D：0V、E：-15V、F：-20V、G：-40V、H：-60V、I：-80V；
100: Output current level, can be divided into 10A, 30A, 50A, 100A;
D: Four-quadrant, bipolar power supply (if D is not included in the model, it is a unipolar power supply);
S: Built in AWG signal generator (without S in the model, there is no built-in signal generator);
R: The output impedance is adjustable (if there is no R in the model, the output impedance is not adjustable).
