Choosing the right phase converter for your three-phase elevator installation where only single-phase power is available can save thousands of dollars per year. The price of electricity is unlikely to ever come down, so these savings will both increase and compound with time.

The average cost of electricity in the United States, across all sectors, was 6.75 cents per kilowatt-hour in January of 2001. As of January 2021, it was 10.35 cents, and that price continues to climb. Yes, the price has nearly doubled in twenty years! Most utility customers pay more than the above average rate (which includes industrial users, who receive a significant discount), which makes the rising costs hurt even more.

Even a modest elevator installation, such as in a small residential apartment building, can use thousands of dollars per year in electricity while idle when powered with a rotary phase converter. Rotary converters can use power equivalent to a household oven -- when they're just idling! The Phase Perfect® has standby power usage more in line with an incandescent light bulb.

The modern, microprocessor-controlled, Phase Perfect® is able to respond instantly to power demands ensuring the power is there when you need it, but power isn't wasted when you don't.
