Converting single phase power to three phase is essential for running many types of industrial and CNC motors efficiently. If you have a shop with machinery that requires a heavy electrical load, you probably need three-phase power to use those machines. With an IP20 enclosure rating and RS485 communication mode, the inverter can work at (–10℃, 40℃). The first phase converters were invented nearly one hundred years ago. Static phase. . 1-phase/3-phase 220VAC input (±15%, 0-75A, 50/60Hz); 3-phase 220VAC output (0-75A, 0-400Hz, 18KW). This vfd is used on ≤20HP (15kW) 55Amps 200-230V 3-Phase Motor This vfd inverter offers enhanced digital/analog terminals for flexible operation, supporting. .
