Convert singlephase 220V supply into threephase 220V output to run threephase motors where threephase power is not available. Ideal for sites with only singlephase service that need threephase motor operation. Key benefits Enables threephase motor operation from a standard singlephase 220V outlet, eliminating the need to install threephase power. Choice of power ratings (400 W, 750 W, 1100 W) to match a range of motor sizes and load requirements. Variable frequency control from 0 to 99 Hz lets you adjust motor speed precisely for process control and energy savings. Builtin protections (overvoltage, short circuit, overcurrent) keep equipment and motors safe and reduce downtime. Digital display and controls provide clear feedback and straightforward adjustment of operating parameters. What it does and who it fits Function: singlephase 220V input → threephase 220V output with variable frequency drive capability for motor speed control. Compatibility: designed for use with threephase motors that require 220V threephase supply; accepts standard singlephase 220V mains input. Performance: supports continuous operation within the listed power ratings and provides frequency control across 0–99 Hz for wide application flexibility. Safety: integrated protection systems help maintain reliable operation in varying electrical conditions. Practical applications Small machine shops: power threephase milling machines, lathes, or grinders where only singlephase power is present. Pumps and fans: control pump speed and airflow on water systems, HVAC, or irrigation equipment without upgrading the electrical service. Light industrial conveyors and mixers: match motor speed to process requirements for improved throughput and reduced mechanical stress. Operation and installation notes Select the inverter rating (400 W, 750 W, or 1100 W) to suit the motor's rated power and starting load. Use the digital interface to set frequency and operational parameters according to motor and process needs. Ensure wiring and protective devices meet local electrical codes and the motor's electrical specifications. Safety and reliability Overvoltage, overcurrent, and shortcircuit protection reduce risk to connected equipment. The combined variablefrequency capability and protective features provide controlled starts, adjustable speeds, and protection against common electrical faults. This inverter provides a practical, reliable solution when threephase power is required but only singlephase 220V is available, offering selectable power ratings, wide frequency control, and essential protections for motordriven applications.
