The APS-7300 3000VA Programmable AC Power Source is a robust and versatile single-phase AC power supply engineered to meet the demanding requirements of R&D labs, automated test systems, and production environments. It provides a wide output voltage range of 0–310V and a frequency range of 45Hz–500Hz, with a maximum power output of 3000VA and a peak current capability of up to 60A, enabling simulation of various global power conditions and voltage anomalies. Equipped with advanced measurement functions, it offers precise real-time monitoring of voltage, current (RMS/peak), power (active/reactive/apparent), power factor, crest factor, and total harmonic distortion (THD). The APS-7300 supports multiple output modes including AC, DC, and AC+DC, and includes programmable waveform synthesis and harmonic distortion generation for EMC pre-compliance testing and product validation. It features a high-speed transient response, low distortion sine wave output, and protections such as overvoltage, overcurrent, overpower, and overtemperature. Connectivity options including USB, RS-232, GPIB, and LAN enable seamless integration into automated test systems, while a user-friendly front panel with a 5-inch LCD display ensures intuitive local control. With its high stability, low noise, and compact 3U form factor, the APS-7300 is ideal for testing consumer electronics, power supplies, medical devices, avionics, and other critical equipment under precise and repeatable power conditions.
