Custom Variable Frequency Drive design for AC motors, fans and pumps

Custom VFD Design – Cabinet Blower Control

Custom Variable Frequency Drive Design for 3-phase 1/2 HP Cabinet Blower Control The challenge of this custom variable frequency drive design was to maintain constant airflow by changing motor speed as the filter changed from “no load” to “100% load”. The custom VFD design had to fit into an existing control panel with a height limitation of under 2.5 inches. Fast start-up (<5 seconds) and intelligent setpoint return are some of the programmed features of this unique custom VFD design.

CRI’s ISO 9001:2008 registered electronic design and manufacturing facilities have the capability to provide complete custom variable frequency drive design for AC motors, fans and pump applications from prototype to production.
