Versatile AC+DC Power Sources

A series of compact, programmable AC power sources with DC output and precision measurement capabilities, Preen AFV-P, come in four power levels: 600, 1,250, 2,500, and 5,000VA, providing clean power with THD less than 0.3% at 50/60Hz. They deliver a continuously variable output voltage of 0 to 310VAC and frequency of 40 to 500Hz (optionally 15 to 1,000Hz). They are ideal for commercial, defense, and aerospace test applications that range from design verification, quality assurance, ATE to mass production.

The series provides comprehensive programmable features (step/ramp/transient) and a total of 1,200 test steps in 50 built-in memory sets, as well as a transient generation functionality that allows simulations of voltage variations, surges, sags, dropouts, and frequency disturbances for simulating global AC power conditions. With advanced PWM technology, the series can deliver up to 4.5 times peak current from its rated output, which is ideal for motor-type tests of inrush current. Users can adjust the starting and ending phase angle from 0 to 360-deg.

Measurement features in the AFV-P series include RMS voltage, RMS current, true power, apparent power, power factor, crest factor, reactive power, etc. An intuitive 5-in. touch screen with an additional rotary knob control allows quick adjustments and configurations of voltage, current, and frequency. The AFV-P series can also be remotely controlled via standard interfaces. Free control software and a LabVIEW driver are available for easy programming and remote operation.
