Preen AFV-P Series Programmable AC Power Supplies from Saelig

Saelig Company, Inc. has introduced the Preen AFV-P Series of programmable AC power sources with DC output and precision measurement capabilities. These compact power sources come in four power levels: 600VA, 1250VA, 2500VA, and 5000VA, providing clean power with THD less than 0.3% at 50/60Hz. They deliver a continuously variable output voltage of 0-310VAC and frequency of 40-500Hz (optionally 15-1000Hz). They are ideal for commercial, defense and aerospace test applications that range from design verification, quality assurance, ATE to mass production.

The AFV-P series provides comprehensive programmable features (step/ramp/transient) and a total of 1200 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 AFV-P 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 - 360 degrees.

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" 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.
