VA.. Electronic speed-controller Single-phase motors only
The VA range is an electronic type speed-controller which provides infinite variation of fan speed from 100% down to approximately 30% of full speed.
When used to control a number of identical fans the sum of the full load amps of all the connected fans must not exceed 85% of the maximum rating of the controller.
The fans should be identical.
Power consumption is reduced by up to 70%.
The motors must be designed for speed control.
Check with our Sales Department before using the VA controllers with EV fans, or with run-on timers.
To minimise electronic hum from larger PSC (Permanent Split Capacitor) motors, a constant active is connected to the start winding via the capacitor and the run winding is regulated by the speed controller. (4 wire connection)
A PSC motor is sometimes referred to as a Capacitor Run motor.
