频率转换器

converterEC5000 series of Frequency Converter Drives are designed to be highly reliable with high-performance, yet easy to use. It can satisfy users' need for changing the speed of fans or pumps, as well as improve the productivity. The series are compatible with all types of three-phase medium voltage asynchronous motors. EC5000 series frequency converter integrates digital technology, computer technology, and modern auto-control technology. It has many merits like high accuracy, low noise, large torque, reliable performance. Therefore, it is applicable for industries like electron, machine, metallurgy, weaving, printing, petrol and, chemistry. It takes important in improving automatization level of industry, and gets high reputation from industrial members.Features:1. High torque output and flexible designThe flexible design will satisfy all of requirements. Realize high starting torque and stable torque in low speed by unique vector control of this company. 1). Realize 150% of torque at 1Hz.Comparison of the torque features between vector control and V/F control.2). Built in braking transistor External braking resistor will get much more braking power.3). Enrich protection function Limiting function in high speed current will restrain vibration from over current(more than 250% of rated current)Upgrade none vibrated running (restart after instant stop, stall prevention, failure reset Built in surge restraint unit Perfective grounding2. Sufficient functions1). Multi-runningMulti-speed running (max 8 speed),UP/DOWN running, and job running.2). Program library with rich drive experience PID control Energy Saving control3). All kinds of convenient function Slip compensation, over torque detection, speed searching.4). Mode of input/output O-10V,4-20mA,0-20mA, Analogue monitor Multi-function input terminal 3. Easier operation & maintenance Reactive design of the keyboard can be completed easily, only to connect power can be used. Replace cooling fan in convenience. Integrate complicated parameters by UP/DOWN.The operator with copy function will be more convenient in application.1). Connected to the power supply to immediately runSet running frequency using operatorClient can install the wire of operator in panel for remote control 2). Easy maintenanceDetachable cooling fan will be switched ON/OFF to control fan running, enhance the service life and reliability.3) Ease installation4). Easy parameter managementUsing the operator with copy function can be replaced once and then run again4. World standard 1). Match the standard in automation field 2). Correspond with specification of every country 200V (single/three phases) 400V (3 phases)3).Standard RS-485,correspond with DevicENet, Profibus-DP (SIEMENS) and Interbus-s 5. Wide range of use Take World is quality No.1as the goal. Apply to multi-power(220V/400V).The communication port can certainly be used whatever application are.1) Speed change8 segmentsConvey Machinery: Conveyor, Windlass, Lifter2).Stall preventionCommon Machinery: Washing machine, Flusher motor, Locomotion motor3).PID Control Fluid Machinery: Fan, Pump, Blower, Molding machine4).UP/DOWM Running Food Machinery: Pulverizer, Mixer, Agitator5).Slip Compensation: Printing, Textile, Lathe Machinery: Corrugated printing machine, Textile machine, Printing machine, Digital lathe machine6).Energy saving control Air conditioner: Refrigerator, Extermal air conditioner, Air compressor
