with service sizing (see next question), the power drawn by a phase converter depends on how much load is connected. Converters are actually transformers, passing through whatever current is called for by the load. If the load calls for 100 amps per phase, that's what the converter must deliver - and will deliver, if it has been sized properly.

Phase Perfect digital phase converters are a revolutionary new concept in digital phase converters. Utilizing the latest developments in solid state electronics and computer control, it balances three-phase voltages to within 1% under all load conditions with true unity power factor and virtually no harmonic distortion. No other phase converter can equal this performance.

No! In general, some units on the market are badly unbalanced with all electrical capacity loaded up on one phase of the internal winding. This generates excessive overheating and often leads to converter failure. Another consumer objection is the high amount of noise generated from this method of construction. Yes! Our manufacturing attention is very detailed. Every unit is balanced by our technical staff resulting in outstanding performance for you the consumer.

Yes! When Superior Phase Converters are running, you may start and stop motors without any limitations or sequences.

Extremely efficient. Losses are generally less than 15% and usually under 10%. One must remember, however, that only one third of the total energy consumed by the load actually passes through the converter. Therefore, the total loss of the converter system is 15% of 33% or about 5% of all the energy consumed. That translates to 95% overall efficiency.

Listen to our sound-level data and find out. Phasemaster® converters have been designed to run quietly and without vibrations. The sound level is the same or less than a motor of the same horsepower as the load. Normally the sound level will measure 72 decibels or less at no load and will decrease when load is applied.

Typically Superior Phase Converters will out last the equipment that it operates. The converter is designed to run continuously at low amperage, so it stays cool. You can expect many years of trouble free service from our units.

No! Energy savings is the heart of our design. Our customers often tell us that they leave Roto-Master running during lunch hours and other periods of work stoppage, without a noticeable increase in their electric bill.

No! It is among the easiest to install because we incorporate a terminal block connector inside our pre-wired control panel for added convenience. We recommend that installation be performed by a LICENSED ELECTRICIAN. All local rules and codes should be followed.

Performance of electric motors hooked to Superior Phase Converters compares very favorably to three phase power. Locked rotor, full load torque, breakdown torque and full horse power development are achieved as if connected to three phase.

Yes. In fact, many even recommend them. Unless you are planning to operate large motors in a residential area, you generally will not need to consult your utility prior to installing a converter.

Phase converters are most often installed next to the incoming single-phase service panel. They may also be placed near the load equipment. For outdoor use, converters should be kept in a sheltered area or in an enclosure. Kay Industries offers an outdoor fiberglass enclosure and also manufactures a totally enclosed converter suitable for the most severe environments.

In truth, phase converters are reliable machines and require very little maintenance. Converters should be regularly inspected to see that their ventilating slots are open and unobstructed. Converters that contain automatic controls should have their contacts inspected at scheduled intervals. Bearings are factory sealed and require only a periodic shot of grease to give many years of trouble-free service.

If your phase converter is properly sized, the voltages and currents should balance without further adjustment.

Yes! Balancing the current on each winding allows this. Since some models on the market are unbalanced, you will need to constantly start and stop the unit to prevent overheating, resulting in additional power consumption and inconvenience. No! Balanced converters start instantly as power is generated on each phase, resulting in low inrush amperage.

When the voltages between the three phases are not equal, the current increases dramatically in the motor windings, creating heat. If allowed to continue, this heat will damage the motor. It is possible, to a limited extent, to operate a motor when the voltage between the phases is not balanced. To do this, the load must be reduced. As a rule of thumb, if the voltage is out of balance by just 5%, the motor must be derated to 75% of its rated capacity.

Three-Phase Power - A type of power supply usually used for operating heavy loads. The three conductors of an HV system or (confusingly) the four conductors of an LV system (three live and a neutral). Kilo-Volt Amperes (KVA) - A measure of electrical power. The capacity of a supply is measured in KVA's. (KVA) - A measure of electrical power. The capacity of a supply is measured in KVA's.

Three-phase motors are less expensive than single-phase motors for motors of one horsepower or larger. Also, they are mechanically and electrically simpler than single-phase motors. This means they are more reliable. A three-phase system can use smaller wires and conduits than a single-phase system.
