Feature:1. The software algorithm and circuit design are used, through the advanced current sampling mechanism, and the switch is used to enhance the protection of the inverter and its peripheral equipment and enhance its safety.2. The PID control unit of the inverter has excellent performance, fast calculation speed, short response time, and can quickly reach the equilibrium value3. The inverter has a built-in three-phase high-accuracy automatic AC voltage stabilizer with automatic voltage adjustment function. When the grid voltage changes by 10%, it can automatically keep the output voltage constant.4. With V / F control, non-inductive vector control, switch flux vector control, open loop torsion control, PG vector control and other control methods5. Independent current loop control for true torsion control, supporting on-line switching of torsion and speed control6. Adopt wide voltage design, input voltage range is 320V-460V, it can be protected from the influence of voltage fluctuation during using, stable and reliable7. With multi-stage speed running function, through custom control terminals, simple PLC function can be realized, up to 16-stage speed running and setting of 4-stage acceleration8. The inverter has 7 frequency sources including keyboard setting, analog voltage setting, analog current setting, multi-speed running setting, PID control setting, remote communication setting and keyboard encoder, etc.9. With automatic torsion boost function, it can realize low frequency (1HZ) large output torsion control under VF control mode, and the corresponding torsion time is less than 40 microseconds10. Intelligent setting of suitable parameters, no complicated and tedious parameter setting required, suitable operating parameters can be set according to the purpose, only the type of the motor is used to achieve fast G-type and P-type load adjustment, automatic setting the most suitable parameters11. By automatically detecting the load current, adjusting the output voltage, and carrying out maximum efficiency control, vector control and V / F control for high-efficiency operation, not only fans, pumps, but also ordinary machinery can exert outstanding energy saving effectsSpecification:Item Type: Variable Frequency InverterModel: SKI670-1D5G-23Input Voltage: AC1PH 220V15% 10A/15A 50Hz-60HzOutput Voltage: AC3PH 0V-380V 9A/13A 0Hz-3000HzMatching Motor Power: 1.5KW2HPRated Current: 15AVoltage Type: AC220V to AC380V (boost)Filter: Built-in filterProtection Level: IP20Machine Size: Approx. 246 x 179 x 150mm / 9.7 x 7 x 5.9inInstallation Size: Approx. 230 x 136mm / 9.1 x 5.4inPanel Opening Size: Approx. 90 x 130mm / 3.5 x 5.1inProduct Advantages: 1.
