Feature: 1. BASIC DATA: Our variable frequency drive uses 3 phase AC380V 50 60Hz input to 3 phase AC380V 0-320Hz output with 20.5A or 26A input current and 17A or 25A output current. 2. RS485 COMMUNICATION: The inverter drive has built in PID controller (presettable frequency). Standard configuration RS485 communication function, multiple communication protocols are optional, with linked synchronous control function. 3. LOW NOISE HEAT DISSIPATION: Our inverter uses a large heat sink with a small fan, and the small fan ensures low noise while assisting good heat dissipation. 4. SMART DIGITAL DISPLAY: 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. APPLICATION: The variable frequency drive is suitable for speed control equipment such as CNC router, CNC machine tool, milling machine, drilling machine, mixer, extruder, ventilator, pump, grinder, centrifuge, etc. Specification: Item Type: Variable Frequency Drive Material: Aluminum Alloy, Flame Retardant PC Input Voltage: 3PH AC380V 50 Or 60Hz Output Voltage: 3PH AC380V 0-320Hz Input Current: 20.5A Or 26A Output Current: 17.0A Or 25.0A Applicable Motor Power: 7.5kW Or 11kW Ambient 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 Droplets Surrounding Environment: Indoor (No Direct Sunlight, No Corrosion, Flammable Gas, No Oil Mist, Dust, Etc.)
