EF20 SFC1/1
Housed in high quality RAL7032 IP20 (or higher) enclosures
A wide range of static frequency converters with comprehensive input and output voltage, phase and frequency combinations.
These units are custom built and have a modular micro-processor based design that makes it incredibly flexible to meet almost any
build requirement.
The power factor corrected rectifier converts the single or three phase mains supply into DC, the PWM inverter then switches back the
DC to AC at the desired frequency and voltage. The output transformer provides galvanic Isolation which isolates the input and output
circuits. Enclosures are high quality steel in RAL 7032 to a minimum IP20. These can be plinth mounted or mounted with castors
for ease of movement. These can be fitted with key locked front access doors or double key locked for additional security.
