What Is A Variable Frequency Drive

What is a variable frequency drive? Variable frequency drives are also known as variable speed drives, VFD's, adjustable speed drives, and inverters. Variable frequency drives are solid state motor control systems designed to control the…

HVAC VFD Repair

HVAC VFD repair should be taken with extreme caution. HVAC VFD repair should only be performed by technicians who have required training and experience to work with electrical equipment. Precision Electric strongly recommends to consult an expert…

VFD Single Phase to Three Phase

A VFD (variable frequency drive) is an electric motor drive and although it will convert single phase to three phase it should never be used as a power source for control circuits, instrumentation circuits, or to operate other electronic components.…

Single Phase to Three Phase Converter

Variable frequency drives can be used as a single phase to three phase converter for AC electric motors. Most variable frequency drive manufacturers design products up to 3 horsepower to convert single phase to three phase. Precision Electric…
