VFD Phase Converters Single to Three Phase Solutions

A traditional phase converter simply generates a third phase from single-phase power with no speed control capability. A VFD phase converter does the same but also allows full variable speed control of three-phase motors, offers soft starting to reduce mechanical stress, provides built-in motor protection features, and typically delivers greater energy efficiency — making it the preferred choice for most modern industrial and commercial motor control applications.

ValuAdd's VFD phase converter lineup covers 0.5HP to 800HP. The GM2 and S Series micro drives handle 0.5–15HP for compact OEM and panel-builder applications, the SW Series covers 0.5–30HP for washdown environments, and the H2 Series scales from 0.5HP up to 800HP for large industrial and HVAC systems — ensuring a matched solution regardless of motor size.

Yes. All products in this lineup support single-phase input with derating applied to account for the reduced current capacity. This makes them well-suited for facilities where only single-phase power is available. Derating guidelines vary by model and power range, so it is recommended to consult product specifications or contact ValuAdd's engineering team to confirm proper sizing for your application.

Communication capabilities vary by series. The H2 Series supports RS-485 Modbus-RTU, BACnet, and Metasys-N2. The GM2 and SW Series include Modbus-RTU via an RJ45 port. The S Series supports Modbus-RTU, Ethernet IP, Modbus TCP, and Profibus-DP as standard or optional protocols. This breadth of options simplifies integration into existing SCADA, BMS, and industrial automation networks.

The SW Series Washdown Drives are specifically designed for harsh environments, featuring a UL Type 4X (IP66) polycarbonate enclosure that exceeds NEMA 1, 12, 4, and 4X standards. This makes them suitable for food processing, chemical plants, and marine applications where high-pressure washdowns or exposure to moisture, dust, and corrosive substances are routine operational conditions.

Yes. The H2 Series includes optional pump and fan application software with advanced features specifically developed for water/wastewater, irrigation, and HVAC systems. It also supports BACnet and Metasys-N2 protocols commonly used in building management systems. Built-in EMC filters on 480V models further ensure compliance with electromagnetic compatibility requirements typical in these regulated environments.
