Programmable ac power source includes dc output capability

INTEPRO SYSTEMS AFV-P Series precision, programmable ac-dc power sources are compact rack-mounted units, available in four power levels – 600VA, 1250VA and 2500VA (2U) and 5000VA (5U). Units provide clean power with distortion less than 0.3% at 50/60Hz and deliver output voltage from 0 to 310Vac and frequency from 40 to 500Hz (15 to 1000Hz with the high-frequency option). Devices can also be programmed to provide dc power from 300W to 2500W at 0-210/0-420Vdc. Units deliver 300µs slew rate (for 0-90% change in output voltage) and can deliver up to 4.5 times peak current (crest factor) from its max rated current. http://www.inteproATE.com
