Behlman BL1350 AC Power Supply

The Behlman BL1350 is a AC power source and frequency converter designed for demanding industrial and testing applications. It has a stable and regulated AC output with fully adjustable voltage and frequency, low total harmonic distortion (THD), and excellent line and load regulation. The unit features a unique overload protection system that folds back voltage to maintain rated current without output waveform distortion, and offers options for enhanced control and functionality.
