With
increasing Global trade, manufacturers in India need to test equipment
on commercial line supply available in those countries. Equipment
exported to several countries require 115V supply at 60Hz. Equipment
used by aircraft industry needs 115V supply at 400Hz. Crotech
is the largest manufacturer and exporter of Frequency Converters
upto 100KVA capacity in single phase & 200KVA in 3 phase catagory. |
|
An
Crotech Frequency Changer consists of a Rectifier and a Static
Inverter. The Rectifier converts the commercial AC power to very
precise DC power and supplies the Static Inverter. The IGBT-based
Pulse Width Modulation (PWM) technology is used to convert DC
power to a very precise low distortion Sine-wave output at very
high efficiency. |
