GoHz Single-Phase Input to Three-Phase Output Variable Frequency Drives (VFDs), available from 1/2 hp to 15 hp, provide an efficient motor control solution for HVAC and building automation systems. Designed to convert 220V, 230V, or 240V single-phase 50/60Hz input power into three-phase 220V, 230V, or 240V output with an adjustable frequency of 0–400Hz, these VFDs enable the use of high-efficiency three-phase motors where only single-phase power is available. In HVAC applications, GoHz VFDs precisely regulate the speed of fans, pumps, compressors, and blowers according to real-time heating and cooling demands. Instead of operating continuously at full speed, motors automatically adjust to changes in occupancy, temperature, and airflow requirements, significantly reducing energy consumption and lowering operating costs. Variable-speed operation also minimizes motor noise, creating a quieter and more comfortable indoor environment. GoHz VFDs support communication protocols such as Modbus, allowing seamless integration with building management and automation systems for centralized monitoring, remote control, and preventive maintenance. Built-in soft-start, overload protection, overvoltage protection, and fault diagnostics improve equipment reliability while extending the service life of motors and mechanical components. Combining energy efficiency, intelligent automation, and dependable performance, GoHz 1-phase to 3-phase VFDs are an ideal solution for commercial buildings, hospitals, hotels, schools, offices, and other modern HVAC applications.
