Foshan where to sell L0550G3 Ling Chuan inverter, how the price? Quality okay L0550G3 Guangzhou-Ling Lu Chuan inverter technology is one of the main products. LCV12 Ling Chuan inverter series is a versatile high-performance vector inverter, is the real current vector control inverter to control theory based on advanced technology, by means of intelligent control, inverter control system allows the governor reached high response, stability, so that really can be applied with ease in a variety of industrial field. L0550G3 Ling Chuan Drive Features: 220V voltage class (single-phase power supply) 0.4-2.2kW 380V level (three-phase power) 0.75-600kW variety of control vector control without PG: apply to all situations require variable speed drives; with PG Vector control: high-precision speed control, torque control applications; no PG V / F control: the traditional inverter control enables an inverter drives multiple motors. V / F control can be selected for use in the V / F curve; it can be set to any of the V / F curve. Constant torque characteristic curve of constant torque characteristic is used for general purposes, independent linearity run like a conveyor belt, and decreasing the use of premises constant torque speed torque characteristics; as fans, pumps, as the power of the relationship between the speed of the load was two occasions, using Such high starting torque curve; a large output torque (lift load) wiring distance is long between the inverter and the motor (about 100m above), requiring start, AC reactor should be added at the input or output of the inverter. High starting torque control without PG: 150% / 1Hz; with PG control: 150% / 0rpm; actual test results: 200% of the starting load a smooth start, and stable fixed line one minute, no overcurrent warning. Reserve power margin and more suitable for a variety of heavy-duty starting occasions: mixing machinery, crushing crushing machinery, lifting machinery, steel rolling machinery. Current vector control at low speed stability, while controlling the motor and the primary current phase, independent control of field current and torque current to achieve a smooth running at very low speed. When vector control without PG 0.5Hz has stable operation; when vector control with PG 0.1Hz able stable operation. To maintain the same output torque of 100%. While we do not recommend long-term operation at such low conditions, but in some special occasions, without gear box for customers to reduce costs. Self-learning-precision vector control mode, based on the precise motor parameters, dynamic self-learning mode to measure the motor from low to high frequency bands of different parameters, to obtain accurate motor parameters, to establish the motor corresponding frequency band in a different frequency band model, from low to high frequency inverter can accurately control the motor. PID control PID control functions can be implemented using closed-loop control. The so-called closed-loop control, the process value with sensor feedback, the inverter output frequency (motor speed) is consistent with the instruction of the target control. PID feedback control is based on the value of the sensor application as valid for the following: 1. Speed ??control: using a pulse encoder speed detection, so consistent speed regardless of the size of the load, or synchronous operation with other motors. 2. Pressure control: the detection value of the pressure sensor as feedback, the pressure must be controlled. 3. Flow control: using the flow sensor, the flow rate can be controlled with high accuracy. 4. Temperature control: The temperature sensor detection value of the feedback, the fan speed to achieve temperature control. Appropriate action can be made according to the set automatic restart after instantaneous power failure instantaneous power. Within a set period of time or move the control voltage is not lost when power is restored, then again, the drive can be automatically re-start.
