Reliability, quality and construction of the PHASE-A-MATIC “KW” Rotary Phase Converter:
Designed for outdoor use and areas of high moisture.
WeatherPhase™ features rating: Intent of USCG 259 and IEEE 45 (Stainless steel nameplate is stamped USCG 259, Ieee45). Treatment of windings and mechanical parts are for applications outdoors or in areas of high moisture. Motors are double dipped and baked in standard insulation varnish. Pipe tap lead outlet in conduit box. IP Protection IP55. It is important to note this converter is not waterproof. This converter is not intended to guard against salt water corrosion. When used outdoors, we recommend installing inside an enclosure with ample ventilation.
Where waterproofing, guarding against salt water corrosion, or any other special requirement is needed, Phase-A-Matic will provide a quote. Custom orders require a minimum of 8-9 weeks lead time.
The rotary portion of our converter is proprietary, custom built to our specifications by Baldor Electric, one of the largest and most trusted motor manufacturers in the world, with warranty stations nationwide and worldwide. It is a true phase converter and not a modified electric motor as most of our competitors use. Many years of testing, changing, and developing the converter in conjunction with Baldor’s engineers has produced a very simple and trouble-free converter with extremely low idle current and relatively low noise level. Many of our customers confirm that our rotary converters are the quietest and most trouble-free available, compared to other converters on the market.
Keeping the design exceptionally simple reduces the risk of electrical connection failure to almost zero since these are some of the most common causes of failure. We use only soldered connections with no mechanical electrical connections like spade clips, terminals or screws which can vibrate loose or corrode over time. There are no start capacitors, relays or contactors with connections which can come loose or arc and weld the contacts causing failure of the contactor and the start capacitors, and perhaps even the rotary converter or your equipment. Because of this we do not have circuit board failures caused by spikes generated by the magnetic contactors as some of our competitors do.
The PHASE-A-MATIC failure rate is practically zero because the rotors are specifically designed and manufactured for rotary converter use. However, some of our competitors emphasize that rotors often fail. This is because they machine standard electric motors, modifying and thereby weakening standard electric motor rotors, which were not originally designed to be used as a phase converter.
The most likely warranty repair would be bearings or windings, which are very rare. This type of failure is much less than 1%, and if it is going to happen at all, most likely would occur within the first 12 months. Failures after that are extremely rare. See MTBF below.
