AC POWER SUPPLY
FREQUENCY CONVERTER / INVERTER

BL-PLUS Series
THE WORLDWIDE CHOICE FOR QUALITY AC POWER

Behlman's BL-PLUS Series High Power AC Source/ Frequency Converter provides the performance of a linear with all the benefits of a switching amplifier. Instead of relying on large, noisy motor generators for AC power, today's testing facilities are switching to quiet, compact Behlman AC Power frequency converters.

Behlman's Solid-State BL-PLUS offers greater energy efficiency, reduced downtime, and a significantly smaller footprint. They're ideal for avionics, airborne and shipboard equipment as well as international products testing. The BL-PLUS even comes with an optional computer control for Automatic Test Equipment (ATE) application. It's adjustable voltage and frequency provides maximum flexibility. 

Combined with The efficiency of the BL-PLUS Series and the savings in converting from a motor generator really add up.

 

Features

  • Precise Adjustable Power: Variable amplitude & frequency with performance quality of a linear and the benefit of switching technology with option "M"

  • Small Footprint: 120KVA is only 27"Wx36"Dx78"H

  • Low Input Current Distortion: Multi-pulsed input transformer and soft start circuitry assures that it will not adversely affect other equipment on the power line

  • Line Drop Compensation for Remote Regulation
