Product Description:

The PSI63C0.747-W1 Frequency Inverter operates as a versatile electric drive system for power conversion applications. This product comes from manufacturer KEB and provides customizable motion control solutions to optimize requirements as well as increase production efficiency.

The PSI63C0.747-W1 frequency inverter comes with a simple design by weighing approximately 25 kilograms. It requires a precise tightening torque between 6 and 8 Newton meters during installation to ensure active operation. When housed within a switch cabinet, it generates a baseline energy loss of 69 watts under normal conditions. Also, when operating at peak performance, this loss increases to a maximum of 110 watts. The highest cooling loss capacity reaches up to 420 watts for this PSI frequency inverter by making effective thermal control that is necessary for optimum efficiency. The PSI63C0.747-W1 frequency inverter consists of a water-based cooling mechanism to maintain stable temperatures and prevent high heating The minimum required flow rate for the coolant is 4 liters per minute which helps in ensuring consistent heat dissipation. At this flow rate, the typical pressure drop within the cooling system is approximately 0.1 bar.

This PSI63C0.747-W1 frequency inverter needs functioning within a voltage range of 400 to 480 volts by tolerating a high-power application. It operates at a standard 110 amperes from the power grid which demonstrates its ability to manage high electrical usage. This drive works smoothly in specific industrial automation locations which contain humidity reaching 95% due to its industrial-grade design. The unit shows resistance against vibrations that fall within severity level requirements for demanding mechanical conditions. EMC safeguards protect the unit by preventing interference to maintain stable operation with other electrical devices.
