Due to requests from our customers for a cheaper alternative to our state of the art DIGITAL PHASE CONVERTERS we have now produced a range of the old design rotary phase converters, these are built to the highest standard but we are able to supply them at a far better price than anyone else,

A ROTARY CONVERTER is not the perfect phase converter, the term ROTARY comes from the fact that these have an internal motor running and this is used to assist the unit produce the third "PHANTOM" phase, this phase if often not at the ideal voltage or even the correct phase shift that TRUE 3 phase requires BUT its close enough for a large range of less demanding applications and its cheaper to purchase than the DIGITAL systems, on the down side the unit is noisy because of the internal motor running and that motor is using power all the time even if you are not running any machines from the converter, this waste of power gets worse the bigger the converter due to the larger motor being powered, also due to the miss matched phase and voltage output you will loose a small amount power and the motors wont be running as smooth as if they were running from a true 3 phase supply like the DIGITAL PHASE CONVERTER will give you,

For small hobby applications on a tight budget this may well be acceptable as the converter will often be at the lower end of the power range for converters so the constant power waste will be smaller AND its often not a problem for a hobby user to turn the converter off when its not in use and then switch it on again when they need to use one of the machines, in this case the machine being powered will often be making more noise than the converter so the noise aspect of the rotary converter will not be a problem, our range of the rotary converters covers from 2HP up to 15HP,

Rotary converters are NOT recommended for applications requiring 24 hours a day running,

For any demanding applications where the quality of the power is important such as CNC machines, precision equipment or equipment with electronics or for industrial use where the unit may be switched on 8 hours a day running a workshop and application that require a 24 hour 3 phase supply then you should look at our DIGITAL systems, these DIGITAL converters have perfect phase output voltage and phase angle and they run without any pilot motor so they are very economical on power and they produce very little noise,

There in no minimum load required on a rotary phase converter,

The unit has an input protection MCB,  an input AMP meter, START/STOP push buttons with power on light and 3 PHASE OUTPUT socket with output MCB all mounted in a strong steel case with skid feet.
