Free DeliveryBest Price GuaranteeFree Expert Advice

The Dab Active Driver Plus (formerly known as the PWM) is a variable frequency drive control system for electric water pumps.
Dab's Active driver is made up of
 a built in pressure sensor, a flow sensor and an inverter all in one unit. The box is compact and very easy to install!

The Active Driver can work with any kind of pump: multistage or single stage, surface or submersible. The Active Driver uses the built in inverter to control the speed of the motor. As the flow increases, the speed of the motor increases, maintaining a constant pressure.

Active Driver M/M is compatible with single phase (230v) power supply pumps.
Active Driver M/T & T/T is compatible with three phase (400v) power supply pumps.

►Greater energy saving
►Greater noise reduction
►Eliminates overpressures
►Increases pump life span
►Easy installation
►No water hammer
►Able to run three phase pumps off single phase supply
