New programmable power supplies suit many test situations and power simulations

Saelig Company offers their new Preen AFV-P Series of programmable AC power sources with DC output and precision measurement capabilities. These compact power sources are supplied in four power levels: 600VA, 1250VA, 2500VA, and 5000VA, giving clean power with THD less than 0.3% at 50/60Hz. They produce a continuously variable output voltage of 0-310VAC and frequency of 40-500Hz (optionally 15-1000Hz). They are perfect for commercial, defence and aerospace test applications that range from quality assurance, design verification, ATE to mass production. The series gives 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, sags, dropouts, surges, 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 perfect for motor-type tests of inrush current. Users can alter the starting and ending phase angle from 0-360 degrees. Measurement features in the series include RMS voltage, RMS current, apparent power, true power, crest factor, power factor, reactive power, etc. An intuitive 5" touchscreen with an extra rotary knob control enables quick adjustments and configurations of voltage, current and frequency. The series can also be remotely controlled via standard interfaces. Free control software and a LabVIEW driver are offered for easy programming and remote operation.
