Feature:1. Fast Heat Dissipation: The VFD has a large heat sink with a small fan, which is about 3 times larger than the heat sink of similar products, and the small fan ensures low noise while aiding excellent heat dissipation.2. Keyboard Design: The variable frequency drive has a user friendly keyboard design, with a reasonable layout and easy operation. The digital display on the screen is intuitive and clear. The detachable design facilitates remote control.3. Wide Application: The variable frequency drive is widely used for speed control equipment such as CNC routers, CNC machine tools, milling machines, drilling machines, wing spreader machines, mixers, extruders, slitting machines, winders, compressors, ventilators, pumps, grinders, conveyors, elevators, centrifuges, etc.4. 3 Phase: A 3 phase motor has better efficiency and output compared to a single phase motor, allowing it to operate for extended periods without overheating.5. Accurate Control: The VDF allows for accurate speed control without sacrificing the motor's energy efficiency. It helps to save energy, reduce wear and tear on the motor, and increase the lifespan of the motor.Specification:Item Type: Variable Frequency DriveMaterial: Aluminium alloy and pc flame retardantModel : JLS B 4T 15GB 18.5PBInput Voltage: 3PH AC380V 50 60HzOutput Voltage: 3PH AC380V 0-320HzInput Current: 35.0A 38.5AOutput Current: 32.0A 37.0AApplicable Motor Power: 15kW 18.5KWAmbient Temperature: -10 to +40 (If ambient temperature is between 40 and 50, please use at reduced rate)Ambient Humidity: 5%-95% RH, no condensation of water dropletsAmbient Environment: Indoor (no direct sunlight, no corrosion, no flammable gases, no oil mist, no dust, etc.)Altitude: 1000m or more, 10% reduction for each 1000m riseProtection Level: IP20Cooling: Air cooled, with fan controlTypical functionsMulti Speed and Oscillation Operation: 16 programmable multi speed controls, various operating modes available.
