Variable Frequency Drive, AC 220V Input 4KW Variable Frequency CNC Drive Inverter Converter, VFD 5.5HP 1 or 3 Phase Input, 3 Phase Output, CNC Motor Inverter Converter for Motor Speed Control
Powerful Function: This variable frequency drive has a 1 or 3 phase input and 3 phase output. Control mode: V/F control and vector control. Frequency setting mode: digital setting, analog setting, serial communication setting, PID setting (advanced calculus PID closed-loop arithmetic, quick responding speed, and high suitability), etc. Various control techniques by both synchronization and non-synchronization dynamically realize fast starting without changing brakes. Heavy load high torque, 1Hz up to full torque.Low-Noise Operation: The phase converter features low noise and low electromagnetic interference through the optimization of PWM control technology and electromagnetic compatibility of the overall design. There is enough space for heat dissipation between electronic components, and the shell adopts porous heat dissipation, which has a longer service life.Smart Digital Display: The VFD adopts a user-friendly keyboard design & reasonable layout, easy to operate; digital display, intuitive and clear. The detachable design is convenient for remote control.Multiple Protection: We adopt various protection ways to ensure the stable and reliable operation of the CNC variable frequency drive inverter. Such as overload protection, fuse protection, over-voltage (DC voltage>400V), or under-voltage (DC voltage<200V) protection, restart protection, stall protection, short-circuit protection, and over-heat protection.Versatile Use: The main application area involves a spindle motor, CNC engraving machine, CNC milling machine, CNC machine tool, milling machine, drilling machine, trimming machine, mixer, extruder, slitting machine, rewinder, compressor, ventilator, pump, grinder, conveyor. Speed regulators such as elevators (cannot be used for passenger elevators), centrifuges, etc.

Metal Detector Waterproof Disc Metal detectors Underwater Underground high Accuracy LCD Display Metal Detector for Adults and Children Headphone Automatic Detector
2 Accurate Detection Modes: All-detect mode can detect all kinds of metal objects, such as coins, cultural relics, jewelry, gold, copper, silver, etc. While discrimination mode can distinguish the valuable objects and skip the useless ones that you don't want. It can also work normally in shallow water thanks to its waterproof design.Powerful LCD Screen: The detected objects are shown on the LCD screen, you can decide which objects you want to detect or not. The detected length is 16 cm / 6.3 in. LCD with light, easily identifying the metal at night or dark places. Battery condition indicator is also equipped.Humanity Designs: Ergonomic arm rest and comfortable grip allow you to use it with little effort. The adjustable stem (ranging from 102 cm / 3.3 ft to 130 cm / 4.2 ft) is suitable for users of different height. The adjustable angle makes it work flexibly on uneven grounds. You may hear different tones as you detect different metal objects, so you don't need to stare at the screen all the time.Practical Shovel and Headphone: It also comes with one headphone and shovel. Headphone jack is near LCD screen, provided for headphone connection. Both stereo and mono headphones are compatible. The shovel has two different heads for different uses.Wide Applications: For adults and children. Children will be thrilled to playing gold-hunting with you. Can be used on any ground, such as grass, soil, beach, yard. Suitable for shallow water.
