Feature: 1. [Input Output Voltage and Current] The variable frequency drive uses 3 phase AC380V 50 60Hz input to 3 phase AC380V 0‑320Hz output, with 3.4A or 2.5A input output current. 2. [Heat Sink and Small Fan] Frequency inverter adopts a large heat sink with a small fan, and the small fan ensures low noise, quiet running while assisting good heat dissipation. 3. [Built in PID Control] Our variable inverter drive has built in PID controller (presettable frequency). Standard configuration RS485 communicating function, multiple communicating protocols are available. 4. [Humanized Designed Keyboard] Frequency inverter drive has humanized keyboard design, with reasonable layout and simple operation. The digital display is intuitive and clear. The detachable design is convenient for remote control. 5. [Wide Use] Variable frequency drive is wide used and suitable for speed control equipment such as CNC router, milling machine, drilling machine, mixer, extruder, ventilator, pump, grinder, 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 Output Current: 3.4A or 2.5A Applicable Motor Power: 0.75kW 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.)
