1. YCB3000 series frequency converter is a general-purpose high-performance current vector frequency converter, which is mainly used to control and adjust the speed and torque of three-phase AC asynchronous motors. It adopts high- performance vector control technology, low-speed and high-torque output, and has the advantages of good dynamic characteristics, super overload capacity, stable performance, powerful protection function, simple human-machine interface, and easy operation.
2. It can be used for driving of weaving, papermaking, wire drawing, machine tool,packaging, food, fan, water pump and various automatic production equipment.
YCQ7 series magnetic starter is suitable for using in the circuits the rated voltage up to 660V, AC 50Hz or 60Hz, rated control power to 45kW and current to 95A. It is used to control the direct start and stop of the motor, and the starter with thermal overload relay protects the motor from overload and phase failure.
Standard: IEC/EN 60947-4-1.
General
YCQ9E series automatic transfer switch, rated working curent 16A to 630A,to be used in pow- er systems for ensuring the continuity of the supply, by transfering a load between two power supply sources. The switch has three working posions of “Main ( I ) cosing”, “Standby ( II )
closing” and “Double-of (0)”, which can be used for fire-fighting linkage and infrequent con-
necion and disconnecion of power supply systems. Mainly used in hospitals, shopping malls, banks, chemical industy, metalurgy, high-rise buildings, military facilities and fire-fighting occa- sions where power failure is not allowed.
Standards: IEC 60947-6-1
The YCQ1F series automatic transfer switch consists of a load isolation switch (without overload and short-circuit protection mechanism) and an intelligent
controller. The switch adopts an excitation type transfer mechanism, which provides faster switching speed.
It also employs a new microcomputer control system for intelligent monitoring and control, strong electromagnetic compatibility, long-term continuous operation, and stability and reliability.
The split-type product can be equipped with an LCD display controller, which is easy to operate, has clear indications, and provides a user-friendly human-machine interface.
General
YCM8 Series circuit breakers were developed according to the demand of domestic and international market as well as features of similar products.
Its rated insulation voltage up to 1000V, is suitable for AC 50Hz distribution network circuit whose rated operation voltage is up to 690V, rated operation current from 10A to 800A.
