Bipolar Power Supply ANBPS(F) Series

The Four-Quadrant Bipolar Power Supply ANBPS Series employs advanced technology combining switching power supply and linear power amplifier technologies. It integrates the functions of both DC source load and high-frequency AC power supply, featuring three output modes: DC, DC+AC, and AC. It is capable of measuring voltage, current, and other parameters, while supporting sequence, synchronous trigger, parallel operation, and external analog input functions. It ensures a reliable and stable power supply operation through multiple protection functions such as overvoltage, overcurrent, and overtemperature. Its superior programming feature, combined with high bandwidth and fast response characteristics, provides efficient and precise power supply variation test solutions for vehicle-mounted and airborne electrical equipment.
