The Preen AFV-P Series of programmable ac power sources with dc output and precision measurement capabilities come in four power levels: 600 VA, 1,250 VA, 2,500 VA, and 5,000 VA, providing clean power with THD less than 0.3% at 50/60 Hz. They deliver a continuously variable output voltage of 0-310 Vac and frequency of 40-500 Hz (optionally 15-1,000 Hz). They are candidates 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 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 AFV-P series can deliver up to 4.5 times peak current from its rated output, which is helpful for motor-type tests of inrush current. Users can adjust the starting and ending phase angle from 0 – 360°.
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. touchscreen 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.
Other product features include:
Start/End phase angle: define the start and end phase angle from 0° to 360°
Current foldback feature: constant output current when output voltage varies.
STEP and RAMP function for voltage and frequency variation tests
TRANSIENT generation provides users an easy setup for power line disturbance (PLD) simulation.
Free control software and LabVIEW driver for programming and remote control.
High slew rate: less than 300 µsec for 0 to 90% output voltage
