First, the product introduction
Product Name: Pump special inverter
Product brand: WeiKen
Voltage level: single phase 220V three phase 380V
Second, the product description
The constant voltage water supply special frequency converter is a kind of power converter that uses the non-inductive vector technology to control the output voltage and frequency to change the running speed of the AC asynchronous motor. Only the current sensor can accurately detect the change of the three-phase output AC signal and the phase angle, and automatically correct the frequency in the non-inductive vector calculation mode to achieve the effect of fixing the motor speed when the load changes.
Third, the special inverter characteristics of the pump
1. Built-in parameter self-learning auto-tuning function, which can automatically detect the motor characteristics and automatically set its related parameters to ensure that the inverter can continuously optimize the motor running characteristics when the motor operating parameters change with time, and obtain the largest Torque output.
2, the entire field of protection functions: low voltage, over voltage, over current, to prevent motor stall, overload, overheating and other protection.
3. Standard V/F mode, non-inductive vector mode, output power (torque) control mode.
4. Control functions designed for industrial machinery: six multi-function programmable digital input functions (99 functions are optional), three multi-function programmable digital output functions (94 functions are optional), timer/ Counter, speed tracking function, flip-flop function, automatic running function, built-in standard RS485 communication interface, can make single or multiple inverters be dynamically controlled by the main computer at the same time, and can control up to 99 inverters at the same time (more than 31 units must be equipped with a relay amplifier), and a built-in rich PID function. The output frequency is 0.00 to 650.00 Hz. The technology is advanced, the structure is compact, and the product looks beautiful and generous.
5, built-in PID regulator, in the realization of constant pressure and constant temperature control, it can easily realize the closed-loop system control of temperature, pressure, flow and other process quantities.
6, our company promises to buy our constant pressure water supply special inverter nationwide warranty for 12 months, lifetime maintenance.
Fourth, matters needing attention
1. When a submersible pump or other load is large, it is recommended to use a frequency converter with a higher power level;
2. When the distance between the motor and the inverter is far away, please install a reactor at the input end and output end of the inverter to avoid the high-order harmonic interference and accelerate the aging of the inverter and the motor;
3. It is forbidden to connect switch devices between the inverter and the open air, especially the leakage protector.
