ARCO CNC Roto-Phase
It is truly like any other phase converter on the market because of its capabilities to provide good starting torque and necessary voltage tolerances of 5% or less to the three-phase equipment load.
The CNC series convertor was developed in the early 1990’s when CNC (Computer Numerical Controlled) equipment began to flood the machinery market. Most standard or heavy-duty phase convertors on the market are not capable of providing the variable speed drive motors of machinery. The CNC series phase converter is able to provide a stable “phase-to-phase” volting condition which is between 1-2% under all loading conditions on three-phase equipment. Unlike our competitors, who use tranformers or capacitor switching via manual switches and contractors, the CNC series converter does not depend on these types of devices which could cause a potential maintenance concern. The CNC series Roto-Phase converter has been field-tested and proven reliable for years. It is truly like any other phase converter on the market because of its capabilities to provide good starting torque and necessary voltage tolerances of 5% or less to the three-phase equipment load. From precision work on CNC machine tool and EDM equipment to lasers used for eye surgery, the CNC Roto-Phase converter is the most reliable on the market. When three-phase power is not available from the utility company or is not economically feasible, then the ARCO Roto-Phase is the best substitute. CNC Roto-Phase converters are available from 1 to 50HP sizes. FOR LARGER SIZES, PLEASE CONSULT FACTORY.
A single phase “Buck & Boost” tranformer may be required for use in conjuction with the phase converter and three-phase equipment, when the single-phase supply voltage from the utility company is higher than then voltage tolerance requirements for the three-phase equipment. CONSULT FACTORY.
