Description
【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 0-2,000 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
80V. 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%.
