Feature 1[Input and Output] This variable frequency drive uses 3 phase AC380V 50 60Hz input to 3 phase AC380V 0320Hz output with 14.6 or 20.5A input current and 13A or 17A output current. 2[RS485 and PID] This variable inverter drive has built in PID controller (presettable frequency). Standard configuration RS485 communicating function, multiple communicating protocols are optional, with linked synchronous control function. 3[Large Heat Sink] Frequency inverter uses a large heat sink with a small fan, and the small fan ensures low noise while assisting good heat dissipation. 4[Humanized Keyboard] This frequency inverter drive adopts humanized keyboard design, with reasonable layout and easy operation. The digital display is intuitive and clear. The detachable design is convenient for remote control. 5[Wide Application] Variable frequency drive is suitable for speed control equipment such as CNC router, milling machine, drilling machine, mixer, extruder, ventilator, pump, grinder, etc.Item Type: Variable Frequency DriveMaterial: Aluminum Alloy, Flame Retardant PCInput Voltage: 3PH AC380V 50 Or 60HzOutput Voltage: 3PH AC380V 0-320HzInput Current: 14.6A or 20.5AOutput Current: 13.0A or 17.0AApplicable Motor Power: 5.5kW Or 7.5kWAmbient Temperature: -10 To +40 (If The Ambient Temperature Is 40 To 50, Please Reduce The Amount Of Use)Ambient Humidity: 5% To 95%RH, No Condensation Of Water DropletsSurrounding Environment: Indoor (No Direct Sunlight, No Corrosion, Flammable Gas, No Oil Mist, Dust, Etc.)Altitude: 1000 Meters Or More, 10% Reduction For Every 1000 Meters Of AltitudeProtection Levels: IP20Cooling Method: Air Cooled, With Fan ControlTypical Functions:Multi Segment Speed And Pendulums Frequency Operation: 16 segment programmable multi segment speed control, multiple operation modes.Pendulums Frequency Operation: Preset frequency, adjustable center frequency, state memory and recovery after power failurePID Control RS485 Communication: Built in PID controller (presettable frequency) Standard configuration RS485 communication function, a variety of communication protocols are optional, with linkage synchronization control function. .wang-edit-text{ font-family:'Arial' !important; } .wang-edit-text table { border-top: 1px solid #000; border-left: 1px solid #000; } .wang-edit-text table td, .wang-edit-text table th { border-bottom: 1px solid #000; border-right: 1px solid #000; padding: 3px 5px; } .wang-edit-text table th { text-align: center; }Package List1 x Frequency Converter1 x Instruction Manual
