KE300A-12 Series Single-Phase 220-In, Three-Phase 380-Out Special Inverter For the civil power (220V), the motor uses 380V field application characteristics, developed a special product which designed with module boosting technology. Optimizing performance design will make the drive no longer complicated. It integrates PG-free vector control, multi-stage V/f control, torque control and soft start functions, and is widely used in applications where speed control accuracy, torque response speed, and low-frequency torque output have higher requirements Features of KE300A-12 Series Single-Phase 220-In, Three-Phase 380-Out Special Inverter • Easy to install and debug • Solid EMC design, unique radiator shape. • Adopt modular design • The main control system uses 32-bit high-speed DSP, integrated PG-free vector control, V/f control, and torque control. • The optimized motor parameter identification model can effectively reduce the sensitivity to motor parameters and make self-learning more accurate. • High starting torque: 150% of starting torque can be provided when it is at 0.5Hz; • Fast dynamic response: Under the vector control mode without PG, the dynamic response time is less than 20ms; • Built-in PID regulator can easily form a closed-loop control system for process quantities such as temperature, pressure and flow. • It has automatic fault reset and power-off reset functions to ensure continuous production and production efficiency. • Perfect protection functions: overvoltage/under-voltage protection, inverter overheat protection, ground fault protection, short circuit protection, overcurrent protection, overload protection, etc.
