Featuring advanced PWM control for low noise and electromagnetic interference, it includes built-in temperature monitoring and multiple safety protections. Ideal for CNC spindle motors, compressors, and industrial machinery, this durable inverter offers versatile control modes including digital, analog, and RS485 communication for seamless integration in professional environments. ## Description Product description 7.5KW 220V Variable Frequency Drive This VFD converter can be used for constant-torque loads ( air compressors, HVAC units, and other hard-start kits.) and variable-torque loads (pumps, fans, etc.). It can also be used as a motor speed controller and phase converter. This VFD features 1- or 3-phase input and 3-phase output, and you can adjust the speed as needed. Adopting sine wave PWN, this inverter’s control system features high torque drive, high-accuracy wide-range speed regulation that has 8-stage / 16-stage speed control, program operation, four settings of acceleration/deceleration time, and more. NOTE 1. The VFD can’t be used as a power source for other equipment, or to drive a motor with a supply voltage lower than 90V. 2. Do not connect the VFD’s output terminals with capacitive loads. 3. Choose a VFD with a larger power output when operating heavy equipment like the crane and compressor, e.g.,a 5.5 Kw motor should be connected to a 7.5 Kw VFD. 4. If a generator is used to power the VFD, ensure that the generator's output voltage level is within +/-15%. Specifications Power: 7.5KW Input Voltage: 220V(+/-15%)/ 180V-250V Output Voltage: 0-220V Input Current: 0-33A Output Current: 0-33A Input Phase: 1 or 3 Phase Output Phase: 3 Phase Input Frequency: 50/60 Hz Output Frequency: 0-1000 Hz Please note: Do not connect to generators that is over 250V. Package Includes 1* 7.5KW VFD 1* Operation Manual 1* Extension Wire Powerful Cooling Fan The fan adopts an independent air duct design for efficient heat dissipation, ensuring that the internal temperature of the inverter is suitable for long-term stable operation. Braking Resistance The VFD can be connected with an external braking resistor (not included), which can consume the energy generated by the motor with an energy feedback device, such as the motor of lifting equipment or centrifugal equipment, and allows for fast braking of the motor, e.g., enabling the spindle of an engraving machine with a peed of 24,000 rpm/min stop within 0.5s-2s.) High-Quality Material The ABS VFD chassis is flame retardant, anti-impact, and corrosion-free. It performs well in protecting the breaker from tripping and has good anti-jamming performance of temperature, humidity, and dust. RS-485 Communication Function With RS-485, a single controller, e.g. a PLC or DCS, can control multiple inverters. Also, this VFD's start, stop, frequency setting, status monitoring and feedback, etc., are all controllable through RS-485. Dual-Chip Design The motor program of the VFD frequency converter is independent from the control program, which features redundant computation, strong anti-interference ability, high-speed running, and stable operation. Multiple Protection Overload protection Overheat protection Over-voltage protection Low-voltage protection Fuse protection Stall protection Short circuit protection Restart protection ## Features - 【7.5KW (10HP) Variable Frequency Drive】Input: 1-phase/3-phase 220 VAC (+/- 15%), 0- 33 A, and 50/60 Hz. Output: 3-phase 220 VAC, 0-33A, and 0-1,000 Hz. - 【Low-Noise Operation & Low Electromagnetic Interference】The PMW control technology and a component compatibility design allow this VFD for low-noise operation and low electromagnetic interference. - 【V/F Control & Vector Control】 The VFD frequency setting mode includes digital setting, analog setting, serial communication setting (RS485 communication port, adopting standard international MODBUS main circuit control), PID setting (advanced calculus PID closed-loop arithmetic, quick responding speed, and high suitability), etc. - 【Improved Safety & Durability】QNK VFD features protective functions for overload, fuse, over voltage (DC voltage>400V) or under voltage (DC voltage<200V), restart, stall, short circuit, and overheat. Moreover, it comes with copper coil internals and a nonflammable exterior for durability and a multi-grid design with enough cooling space between the electronic components and the case for fast heat dissipation.It also can prevent dust, water mist entering the circuit board section effectively. - 【Wide Application】The VFD can be used in various types of equipment such as Spindle Motors, CNC Routers, Milling Machines, Pumps, Compressors, Grinders, among others. - 【Attention】Please Note:1.This VFD surpport external resistor!!! If your motor is heavy load, pls choose a higher power level VFD or contact sales for model selection suggestion. 2.The VFD can’t be used as a power source for other equipment, or to drive a motor with a supply voltage lower than 90V. 3.Do not connect the VFD’s output terminals with capacitive loads.4.Choose a VFD with a larger power output when operating heavy equipment like the crane and compressor, e.g.,a 5.5 Kw motor should be connected to a 7.5 Kw VFD. 4.If a generator is used to power the VFD, ensure that the generator's output voltage level is within +/-15%. - 【Customer Service】If there is an error code in the product and you do not know how to operate,or other questions of this product,pls feel free to contact us.
