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.

The cost in cents per kilowatt/hour your utility charges you for electricity usage. You can estimate costs for your region by looking at the Average Price Chart on eia.gov.

Weeks per Year
Days per Week

Number of weeks per year and days per week you anticipate needing 3 Phase power available. For example: a business with typical operating hours might be 50 weeks per year and 5 days per week, while an elevator installation would require 52 weeks per year and 7 days per week.

Hours Per Day

The number of hours per day you anticipate not drawing a significant 3 Phase load. For example: a typical business might not draw a significant load right away in the morning, during breaks, or over the lunch hour, while an elevator might be idle 20 or more hours per day.
