The APS51 series precision programmable AC power supply is single phase AC power supply with variable frequency from 45Hz to 250Hz. There are three models in the APS51 series programmable AC power supply lab: 300V AC power supply 500VA 2kVA AC power supply 3kVA AC power supply The single phase AC power supply has low range 0-150V output and high range 300V output. There are three sets of memories to store voltage and frequency settings of the variable AC power supply. The single phase AC power source has fast response time 20ms and soft start function to set voltage rise time up to 99.999s. The precision AC power supply is a useful power tool for laboratory and factory.

The TFC63 series are three phase output AC power source, output capacity from 500VA to 800kVA.  

The three phase ac power source can be custom made to high voltage output and high frequency output. The variable AC power source can be made to high power programmable AC power source, 100kVA AC power source, 500Hz AC power source, 115V 400Hz AC power source, 300V AC power supply, AC power supply 500V, high voltage variable frequency AC power supply variable 1000V, AC power supply 400Hz or up to 2500Hz.

The 3 phase programmable AC power source can be used as variable AC power source to simulate grids of different countries, widely used in laboratories, production calibration & test and military applications.
