Variable Frequency Inverter

Variable Frequency InverterProduct Brief: B503 series inverter adopts DSP control system which supplies sensorless vector control(SVC) and V/F control. Comparing with V/F control, the performance of SDP has greater superiority, which consists of Built-in SVC and V/F control, it is widely aplied to high speed contro l accuracy, rapid torque response and high performance at low frequency. Main Features: * Control mode: Sensorless vector control, V/F control, Torque control * Start-up torque: 0.5Hz/150%(SVC) * Built-in breaking unit for 0.4kw to 11kw. If need to stop rapidly, please connect the brake resistance directly. . Mult-step(8 steps)speed control: PID control, Traverse control * Offer 4 multi-functional digital inputs, 2 analog inputs, 1 relay output, 1 analog output, 1 open-collector output. * AVR: Can output constant voltage automatically when input voltage is fluctuating. * Offer RS485 communication interface. * Standard Modbus. Power range:Single phase 220V 0.7HP~3HP(0.4KW~2.2KW) Three phase 220V 1HP~75HP(0.75KW~55KW) Three phase 380V 1HP~860HP(0.75KW~630KW) Introduction Technology Features * Input & Output Input Voltage Range: 380/220V± 15% Input Frequency Range: 47~63Hz Output Voltage Range: 0 ~ rated input voltage Output Frequency Range: 0 ~ 600Hz * I/O features * Programmable Digital Input: Provide 4 terminals which can accept ON-OFF inputs * Programmable Analog Input: AI1 can accept input of 0~10V or 0/4~20mA. * Programmable Open Collector Output: Provide 1 output terminal(open collector output or high-speed pulse output) * Relay Output: Provide 1 output terminal * Analog Output: Provide 1 analog output terminal, whose output scope can be 0/4~20mA or 0~10V, as chosen. * Main Control Function * Control Mode: Sensorless Vector Control(SVC), V/F Control * Overload Capacity: 60s with 150% of rated current, 10s with 180% of rated current * Starting Torque: 150% of rated torque at 0.5Hz(SVC) * Speed Adjusting Range: 1: 100(SVC) * Speed Accuracy: ± 0.5% of maximum speed(SVC) * Carrier Frequency: 0.5Hz~15.0Hz * Reference Frequency Source: Keypad, analog input, serial communication, multi-step speed, PID and so on. The combination of multi-modes and switching between different modes can be realized * Torque Control Function: Provide multiple torque setting source * PID control function * Multi-Step Speed Control Function: 8steps speed can be set * Traverse Control Function * Non-stop when power is instantaneously cut off * Speed trace function: Start the running motor smoothly * QUICK/JOG key: User defined shortcut key can be realized * Automatic Voltage Regulation(AVR) Function: Automatically keep the output voltage stable when input voltage fluctuating * Up to 25 fault protection: Protection from over current, over voltage, under voltage, over heat, phase failure and overload etc. Applications:B503 series(Output frequency range is 0~400Hz) Textile machinery, Plastic machinery, Light industry, Pharmacy machinery, Fan, Water Pump, Air compressor, etc.   /* January 22, 2024 19:08:37 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
