Low-Voltage Variable Frequency Drive Solution for Demanding Applications Liquid cooled AC drives are designed to control the speed and torque on low voltage induction motors. The drives features inverter modules with high-current IGBTs that can be paralleled for a wide range of motor horsepowers.
These drives can be configured as stand-alone units, packaged into a common-DC bus arrangement, or supplied with active front end (AFE) rectifiers for regenerating energy.
Each drive module comes equipped with an integral liquid cooled heat sink for removing heat. Current Power can provide VFDs as part of a packaged solution with any or all of the following products:
Standard drive options are available, but Current Power can provide detailed engineering necessary to meet your specific application within the ratings listed below. For further information, contact sales@currentpsi.com.
