General Interest


The old fashioned STATIC and ROTARY phase converters are the most basic type of converters, they are not much good at all with the STATIC being large and heavy as per the right hand picture above and this STATIC type will oftern have problems running modern motors and when they do run them at all they are not at all smooth and you will have a loss of power and our customers have oftern burnt out small motors using a STATIC type converter !, Keep well clear of them !,

The ROTARY PHASE CONVERTER is a big and bulky as can be seen in the left picture above its an item thats makes loads of racket in the workshop and uses loads of power even before you start your machines and even then the power output is not up to the most demanding tasks, both these types of converters are so simple you can make your own if you want to with plans on how to do this being sold all the time on EBAY but I would not bother as you are sure to be unhappy with the results once you have it up and running !,

Both the STATIC and ROTARY converter have now been dropped from the DRIVES DIRECT product range so these types are basically becoming obsolete now with all discerning users opting for the latest DIGITAL PHASE CONVERTER technology but as we try to assist our customers as much as we can there are oftern times when a customer who already has one of the old STATIC or ROTARY converters and is unhappy with them for what ever reason wants to upgrade to the DIGITAL system and if the unit they have is in good condition we will always do our best to offer them a PART EXCHANGE deal against a DIGITAL unit,

GO DIGITAL - It's the only way to go !


No need to look elsewhere,

We combine the BEST PRICES with the BEST CUSTOMER SERVICE EVER to offer you user friendly POWER CONVERSION and SPEED CONTROL solutions,

We are the ONLY company that offer you a FULL TECHNICAL ASSISTANCE HELP LINE thats open 7 Days a Week from 10AM up to 10PM

We can assist you in powering any 3 PHASE MACHINE from a tiny 90 Watt motor on a clockmakers lathe right up to an entire workshop with 20+ people working machines,

Digital Plug & Play Phase Converters - the NEW version of the old fashioned ROTARY PHASE CONVERTER

You are looking at a NEW 7½ HP Rated Plug & Play 220 Volts Single Phase to 415 Volts 3 Phase Digital Phase Converter by

Drives Direct - The UK's BEST Supplier of Phase Converters and Inverters

This unit is special because unlike other solid state inverters that output 240 Volt 3 phase and thus require DUAL VOLTAGE motors connected in DELTA to produce FULL POWER this unit runs on a single phase 240 volt supply and outputs 415 volt three phase, this will allow a much larger range of machines to be powered in the home as now even special motors like DUAL SPEED types can be powered,


  • DIGITAL METERING - Shows both output Volts and Amps simultaneously

You can use this type of  DIGITAL PHASE CONVERTER in two ways,

In the conventional mode it will allow you to run a directly connected 415 Volts 3 phase motor up to the supply capacity of the converter so 7½ HP in the case of this converter,

It will give you all the normal inverter function of motor control like :-

  • SOFT START - You can program the unit with the required motor start time and the inverter will ramp up the motor to the requested running speed in the time set,
  • FULL MOTOR SPEED CONTROL - Advanced VECTOR control will allow you to have the motor running at very low speed BUT will full power(take motor cooling into account if using for long periods at low speed)
  • ELECTRONIC BRAKE - STOP the motor within a preset time

You can use the removable front panel to control the motor and select forward/reverse or you can use one of the many remote control boxes we stock to control the motor(See EBAY ),


Another SPECIAL feature of this converter is the ability to run it in Plug and Play mode,

In this mode you can take the 415 Volts output of the converter and connect it to your machine so that the existing machines START/STOP buttons and switches will still work to control the machine as if it was connected to a factory 3 phase supply,

You need to take into account the motors starting requirements when sizing up the converter for Plug and Play mode, normally a 3 phase motor will require at start up a surge of 3 to 8 times the normal running power and the size of converter needs to be large enough to provide this power, 

Unless the machine has a very high start load for example in the case of a planer machine because of the cutter block's inertia you can go for a 3 x overload rating, as an example the main spindle motor on a 2HP Bridgeport Mill will require a 6HP surge to get it going,

All this range of DIGITAL Plug and Play Converter allow you to take a 150% overload for 30 seconds so the 6HP starting requirement of the 2HP mill can be accommodated by this 7½ HP converter,

As the output from this unit is a DIGITAL output you can only use it to power normal motor/switch loads and not any items that contain electronics,

If you need to provide power for an item with electronics of any type you will need to fit a SINE WAVE FILTER(See ) to the output, once you have this fitted then you can power machines with electronics in them and even running a CNC machines is possible,

If your machine required a NEUTRAL then this can be generated by fitting a NEUTRAL GENERATOR at the output of the SINE FILTER BUT as an N line is normally just a way for your machine to get back a 220 Volts supply we can oftern talk you through feeding a 220 Volts supply to the machine to power this part of the load thus saving you the cost of an extra part,

This type of Plug and Play system when correctly sized can be used to power a whole workshop via a ring main,

Our technical Help Line is open from 10AM untill 10PM every day so if you have any questions about sizing your converter or selecting option for your application please contact us and we can tell you what size converter will be required, 

This unit will work with any 415 volt three phase motor up to 7½ HP and enable you to use the machine at FULL POWER,  it has an 11 HP SURGE capacity to allow the motor to get up to speed,

At FULL LOAD this unit would require a 220 Volts feed of 40 Amps, these can also be supplied to run on a BI PHASE 480 Volts supply and in that case 20 Amps would be required,

The unit is brand new and boxed and comes with a years guarentee, if you are at all unsure about the wiring of this unit I will offer any help and advice required to get it connected and running in your application, its a very compact unit with easy screw connections and input/output cable glands,

Any questions, please ask, good luck with your bidding.
