Blue Whale BWFCM series solid state / static frequency converter is one of the most popular AC power supplies designed to change AC power at 50Hz to 60Hz or 60Hz to 50Hz, or convert conventional 50/60 Herts to 400Hz or convert 50/60Hz to 16.67Hz/25Hz/100Hz.

BWFCM series static converters adopt built-in rectifier to convert incoming AC power into DC and then invert the DC into desired frequency and voltage thru IGBT and built-in isolation transformer.

“Blue Whale BWFCM series features in many advantages, making them ideal not only for export product testing or operation of imported equipment, but also for applications such as the
testing of military/avionics equipment or for the operation of 400 hertz electronics that are onboard an aircraft or a military vessel.”
