Booster™ A4

4 kW (5.4hp)

Phase Converter 4kW

These medium sized Booster™ rotary single phase to three phase converters are probably the most advanced units available from a UK manufacturer and feature everything  a small workshop could want:

•Compact dimensions
•No user controls
•Fits under a workbench or on a shelf
•Robust lifting handles
•Both a three phase socket and three phase cable outlet as standard items
•One box design with internal motor on anti-vibration mounts
•Continuous use rating with no minimum load requirements

•Shipping £65 UK normal zones.
•Shipping £140 Scottish Highlands/Islands. Eire, Channel Islands and N.I.

 

£1,100.00 (ex. VAT)


These compact Boosters are probably the best medium sized rotary phase converters in the world.

They feature symmetric neutrals as a standard, offer 600% x 10 second overload capability, are rated for continuous use, and are ready to go 'out of the box' .

The motor is tucked away inside the well ventilated case on antivibration mounts which makes them that bit quieter. An easily accessible switch/fuse is on the front, next to the 415V x 5 pin socket and there are no other user controls.

On the back is the 220/240V inlet and a cable gland and terminal block so you can hard wire a 415V outlet to a 3 phase distribution board. They feature electrically noiseless sealed solid state electronic switching so swarf or debris cannot affect the converter, and so the converter will not create electrical interference.

They will run high speed 4250 rpm CNC machinery and just about anything else within their power rating.

We also supply phase converters for passenger lifts and ground source heat pumps but for these applications it is essential to obtain a full specification from the supplier, particularly the total electrical power requirement in kW at full load.

It is very important that you consider cable sizing as part of your purchase, the table below shows you what size cable you should use for your 240V and 3-phase cable runs for this Booster.
