Simple PLC, multistage speed operation	It implements up to 16 speeds via the simple PLC function or combination of DI terminal states.
Built-in PID	It can keep constant output voltage automatically when the mains voltage changes.
Automatic voltage regulation(AVR)	Automatically maintain a constant output voltage when grid voltage changes.
Over voltage/Over current loss of speed control	Automatic limit of the current and voltage during the operation, prevent frequent over current and over voltage
Rapid current limit	Minimizing over-current fault and protect the normal operation of converter.
Torque limit and control	"Excavator" characteristics, automatic limit of the torque during the operation, to prevent frequent over-current trip. Closed-loop vector mode torque control can be achieved.

n******n

Coolmay is designed using industrial-leading technologies. They are mainly CAD design, 2D & 3D printing, and Gait balance analysis tech, and so on.

g******r

Coolmay is inspected in various aspects. The pattern correction is checked based on size set garments measurement, the cut panels inspected before inputting to the sewing section, and fabric bonding strength checked after fusing.

b******p

A comprehensive consideration is involved in designing Coolmay . The correct choice of fabrics, seam technology, stitch workmanship, decision of dyestuff, and other elements are taken into account by professional designers.

t******t

The fabrics of Coolmay have been strictly inspected. They have been checked in terms of yarn defects such as thick and thin, fabric holes, fabrics shade matching, and fabric construction.

r******a

Coolmay has been strictly tested by third-party labs. It has been tested in terms of biomechanical comfort, stress distribution, slip resistance, tear strength, and cut resistance.

g******q

Adopting the cutting-edge water purification treatment technology in the industry, it can effectively filter out harmful substances such as bacterial microorganisms, colloids, suspended sediments, residual fluorine in tap water, etc., so that the water quality can meet the national water quality standards.
