Wardrobe starter with a frequency Converter

Advantages of our equipment 1. The ease of use. 2. Ease of operation. 3. Safety and reliability. 4. Longer service life. Hardware features He has a protective structure of box-type and consists of an inverter, circuit breaker,fuse, fuse, input and output AC reactor, auxiliary relays, etc. It also has a high power factor, the upper and lower limit speed control, positive and negative control of number of revolutions, automatic stepless speed, which are protected against short circuit, overload, overvoltage and undervoltage. Operating current and the rotational speed of the engine can be displayed, and 4-20mA stand signal can be output to connect to the Internet. Scope VVVF series is designed for use with alternating current 50/60Hz,rated voltage of 380V ~ 480V, capacity ≤ 400 kW three-phase asynchronous motor. Conditions of use: 1.Height over sea level up to 1000 m; 2.The average monthly relative humidity not more than 85% 3.Working temperature: -5 ~ 40 ℃ (frequency conversion ≤ 50 ℃) 4.The environment is not explosive, not containing conductive dust, corrosive gases and vapors in concentrations destroying materials and insulation 5.No violent turbulence, the angle of slope ≤ 5 ° Principle of operation It can provide continuous and stable running of the motor,with the flexibility to customize the number of private inrush current after power off and thereby reduce damage to the pulse current to the motor insulation, operating temperature below the motor, to reduce the maintenance of the motor and prolong its service life. Technical parameters （1）motor Power：2.2~400kW each； Input voltage: three-Phase 380 ~ 480V±10%，50/60Hz； (2) speed control Range ：0~100% Stepless； （3）the Signal speed control：、4~20mA；Potentiometer,key increases and decreases 4~20mA （4）the Method of regulating the speed：automatic and Manual software setup （5）torque Characteristics：Constant torque quadratic torque （6）start-stop method：Soft start,soft stop； （7）start-stop time：1~co；1~3600 seconds （8）Protective feature：Short circuit,overload, open circuit phase, overvoltage, low voltage,regulating the speed of rotation of the upper and lower limits； （9）Characteristic dominance：Digital display current power of the motor , rpm, speed , （10）Input characteristic：the supply Current of the electric motor, the rotation frequency and its output signal 4~20mA. （11）Characteristic regulation： continuous PID regulation （12）Other feature： Sizes： VVVF-□/□； □/---Rated power motor (kW)； /□---Voltage rating of the motor (in)； For example：VVVF-160/380 means managing asynchronous motor with squirrel cage 380V/160 kW each brand of converters opt for the users. We will be able to design and form set according to the volume of the motor and equip Converter brand Bosch Rexroth, INVT, Mitsubishi, Schneider, Siemens, ABB and other Welcome to our website: http://www.ytxinhai.com/ru/ or http://www.xinhaimining.net/ Contact person: Mila Duan Mob: +86-18210539147 E-mail: info@ytxinhai.com Skype: xinhaiduan ICQ: 619-151-233
