Underneath the tables there are a few paragraphs with more data. Follow the menu on the left to comments regarding applications for phase converters and prices including our best price guarantee. More detailed information is available by clicking on each product. If there is any other information you want, or if you are unsure as to how to interpret something then please contact us.
In our opinion our Booster range
of rotary converters are the best available from a UK
manufacturer. They feature a 600% overload capability,
electrically noiseless sealed solid state electronic switching,
and a three year guarantee. Models of 3kW or less also feature a
symmetric neutral as standard - the first time this has ever been
offered in the world.
ª Typical continuous duty load specifications. Actual specifications may vary slightly depending upon customer application - please contact us for advice.
*Supply breaker rating & cable sizes are the minimum
with a good quality utility supply and a cable run of 20
meters or less. Where possible use type 'D' motor
rated circuit breakers or fuses. We can advise on how to
handle other circumstances.
** Details on application
Our Classic Rotary is no longer available. After fifty years of making this design we have moved on to the Booster rotary which has proven extremely popular due to its unrivalled performance and ease of use.
Our Classic Static is no longer available. After fifty years of manufacturing these and their companion Classic Rotary we introduced the Booster rotary. The additional performance of the Booster rotary persuaded the overwhelming majority of our clients to select the Booster.

All our components come from reputable suppliers who manufacture to international or British Standards, some of whom produce components to our unique designs and who have been working with us for decades. Our products comply with current EMC regulations and are built to specifications and standards that are within the EEC Electrical Safety Directives and carry the CE mark. A certificate of conformity is available on request.
Our converters are housed in a powder-coated finish mild steel enclosure. Standard fittings on the smaller Boosters (up to 6kW) include a safety switch/fuse (MCB); a 5 pin 16 Amp x 415 Volt socket; and a terminal block for hard wiring in a 415 Volt ring main if required. Standard fittings on the larger Boosters (8kW and above) include a single phase isolator, a stop/start button, and an overload (MCB); a 5 pin 16 Amp x 415 Volt socket; and a terminal block for hard wiring in a 415 Volt ring main.
All units are well labeled and supplied with installation and user instructions. Boost converters can run at full load with balanced phases ± 5%. Boost has the flexibility to produce special units to meet unusual customer needs.
The size of the phase converter unit will normally depend on the HP or kW of the motor(s) or other loads to be run:
No motor larger than the rating of the converter must be used.
More than one motor may be run simultaneously from a Boost converter provided that the total multi-motor rating is not greater than the converter rating, e.g. a 3 HP motor will require a 4 HP converter; a 5 HP motor and a 4 HP motor may be run simultaneously from one 12 HP converter.
