Feature: 1. INTELLIGENT DIGITAL DISPLAY: VFD uses humanized keyboard design, reasonable layout, easy to operate; Digital display, intuitive and clear. Detachable design for remote control 2. GOOD HEAT DISSIPATION: Variable frequency drive adopt large heat sink with a small fan, about 3 times larger than similar products, small fan to ensure low noise while assisting good heat dissipation 3. WIDE APPLICATION: The variable frequency controller is suitable for CNC router, CNC machine tool, milling machine, drilling machine, wingspan machine, mixer, extruder, scutter, winding machine, compressor, fan, pump, grinder, conveyor, elevator, centrifuge and other speed control equipment 4. VARIOUS STAGE SPEED AND SWING FREQUENCY OPERATION: The VFD has 16 programmable various stage speed control and multiple operation modes. The preset frequency and center frequency can be adjusted when the swing frequency is running, and the state memory and recovery after power failure 5. PID CONTROL RS485 COMMUNICATION: The VFD has a built in PID controller(frequency preset), RS485 communication function is standard configuration, and multiple communication protocols are optional, providing linkage and synchronization control function Specification: Item Type: Variable Frequency Drive Material: Aluminum alloy and flame retardant PC Input Voltage: 3PH AC380V 50/60Hz Output Voltage: 3PH AC380V 0-320Hz Input Current: 62.0A/76A Output Current: 60.0A/75.0A Adaptive Motor Power: 30KW/37KW Ambient Temperature: -10℃ ~ +40℃(if the ambient temperature is 40℃ to 50℃, please derate.)
