QNK 4KW 5.5HP AC 220V 17A VFD Converter Single to 3 Phase Inverter Variable Frequency Drive CNC Spindle Motor Speed Controller

About this item

【4KW (5.5HP) Variable Frequency Drive】Input: 1-phase/3-phase 220 VAC (+/- 15%), 0- 17 A, and 50/60 Hz. Output: 3-phase 220 VAC, 0-17A, 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.
【Used in CNC Router, Milling Machine…】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 80V. 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%.
