Detailed Description:
The Powtran PI550 045G3 is a robust and high-performance three-phase to three-phase frequency inverter, designed to provide variable speed control for AC motors in industrial applications. It accepts an input voltage range of 3-phase 380 V (-15%) to 440 V (+10%) and outputs a regulated 3-phase voltage to the motor under advanced vector or V/F control. 

Key Specifications & Features:

• Model: PI550 Series, 045G3 variant (indicating approx. 45 kW rating) 

• Rated Output Power: ~ 45 kW

• Input Voltage: AC 3-phase 380 V (-15%) to 440 V (+10%) 

• Input/Output Phase: Three-phase in, three-phase out

• Control Methods: High-performance vector control and V/F control supported 

• Interfaces and Functions: Built-in PID, multi-speed operation, communication ports (e.g., RS485/Modbus) available Environmental / Operating Notes: Ambient temperature exceeding 40 °C requires derating; ensure proper ventilation and mounting per installation guidelines. 

Usage / Application Notes:
This inverter is well-suited for industrial motor control applications such as pumps, fans, conveyors, mixers and general variable speed drives where precise speed/torque control is required. Installation should ensure proper mounting clearance, appropriate circuit protection (breaker/fuse), grounded motor cables, and correct parameter entry for motor rating. Because ambient temperature, altitude, and supply conditions affect performance, always reference the manufacturer’s manual for derating and installation details.
