AC/AC power supply EPS/ACS series

regulatedswitchingthree-phase

The 4 Quadrant Amplifiers »EPS/ACS« of EPS Electronic Power Supplies are built after the newest state of the art and can be used for the complete simulation of all the technical grids from DC up to 500 HZ, optionally up to 15000 Hz, continuous adjustment of the Voltage and Current, AC, DC as well AC and DC-Output both together. High power outputs, a low distortion factor and an outstanding stability also make harmonic and flicker tests possible even during strong variation in load. The microprocessor-controlled sinusoidal oscillator input with galvanic isolation (option) produces an accurate, stable Voltage and frequency. The output can be regulated fast from 0 up to 300 VAC or 0 up to 425 VDC in the standard-version. Or as an option from 0 up to 700 VAC and 0 up to 1000 VDC respectively. The series is available with one or three phase output power from 400 VA up to 18000 VA and the maximum output current is 40A eff. The units are 25% Power overloadable for short time and can provide high peak currents up to 120A. All parameters can be adjusted with a RS232-interface or optionally with a GPIB, USB or Ethernet Interface. The appliances have proven themselves in the development, licensing offices and in the production over many years. Through the linear power-output stage the operation is possible under difficult load applications and allows a phase triggered switch ON and OFF .
