    • High-Precision Programmable Power Supply

    The high-precision programmable power supply HPS-XXXX series is mainly used in electrical performance testing of automotive electronic equipment and electrical load testing of electronic and electrical components, battery charge and discharge and ripple heating testing, capacitor material testing, electroplating processing and other fields. It has a four-quadrant operating mode, can both provide power and absorb power, and can drive inductive loads and capacitive loads. It has the advantages of output accuracy and low drift at high temperatures, with a minimum programmable time of 3μs in steps of 1μs, which can easily achieve fast programming output, and the output bandwidth ranges from DC to 500kHz. It also supports arbitrary waveforms and can be combined with common waveforms for output. The integrated external voltage detection function can be used as a closed-loop Vpp output to meet the ripple superposition test requirements of ISO16750-2-2023. With the corresponding current and boost transformers, it can
