YK750W SinglePhase 220V ThreePhase Fan Motor Speed Controller Simple Inverter (YK750W) Key benefits Runs threephase fan motors where only singlephase 220V power is available — no need to rewire or existing supply. Provides reliable speed control for ventilation, exhaust, and cooling fans, improving process control and comfort. Simple inverter design focused on straightforward installation and operation, reducing setup time and complexity. What this product does Converts singlephase 220V input to threephase output suitable for fan motors. Allows stepless speed adjustment of threephase fan motors (model YK750W, 750W nominal capacity), enabling precise airflow control and quieter operation compared to fixedspeed fans. Who needs it Facility managers, HVAC technicians, and workshop owners who must control threephase fans but only have singlephase power available. Installers and maintenance teams seeking a compact, nofrills inverter to add variable speed capability to existing fan systems. Key attributes Model: YK750W (YK750W) Input: Singlephase 220V Output: Threephase for fan motor operation Power class: 750W nominal Functionality: Simple inverter with speed control for threephase fan motors Compatibility: Designed specifically for threephase fan motors up to the unit's rated power; ideal where a 220V singlephase supply is the only available source Performance highlights Enables smooth speed regulation of threephase fans to match ventilation requirements. Improves energy use by allowing fans to run only as fast as needed. Reduces mechanical stress on motors by avoiding constant fullspeed operation. Typical applications HVAC systems: Control supply and exhaust fans in commercial or residential ventilation systems where threephase motors are installed but only singlephase power is present. Industrial ventilation: Regulate airflow for dust collection, paint booths, or process exhaust fans to match changing production needs. Workshops and small facilities: Convert existing threephase fan motors for variablespeed operation without upgrading the building's power distribution. Installation and use notes Intended for use with threephase fan motors within the unit's 750W rating; confirm motor power and connection compatibility before installation. Simple inverter design emphasizes ease of integration into existing motor control setups; follow standard electrical practices and local codes for wiring and grounding. Professional installation recommended when modifying motor supply or control wiring. Why choose the YK750W Practical solution to a common problem: operate and control threephase fan motors from a singlephase 220V supply. Focused, purposebuilt inverter for fan speed control — straightforward, effective, and aligned to motor compatibility and power rating. Includes YK750W (YK750W) singlephase 220V to threephase fan motor speed controller (750W class) For results, verify motor power and wiring requirements before and consult qualified personnel for installation and commissioning.
