Danfoss 137H8925 iC7-Automation frequency converter, 250 kW industrial variable speed drive for high-performance motor control and automation systems.
£24,076.00
The Danfoss 137H8927 is a high-performance iC7-Automation air-cooled frequency converter designed for demanding industrial motor-control and automation applications. Rated at 480 A with typical motor power of 250 kW at 400 V in normal-overload duty, it provides precise variable-speed control for large motors used throughout modern machinery and process systems.
As part of the advanced Danfoss iC7-Automation series, the 137H8927 combines powerful motor control with integrated communications, functional safety and extensive control I/O. This configuration incorporates PROFINET RT, an Ethernet interface, coated circuit boards, an integrated brake chopper, AC fuses and a mains switch, together with Safe Torque Off (STO) functionality.
The drive operates from a three-phase 380–500 V AC supply and is housed in an IP21 / UL Type 1 FK10c frame. It supports 250 kW at 400 V under normal-overload operation, with additional high-overload ratings for applications requiring increased starting or transient torque.
Frequency converters such as the Danfoss iC7-Automation regulate motor speed and torque by controlling the frequency and voltage supplied to the motor. This allows motor-driven equipment to respond accurately to process demand while helping reduce mechanical stress and unnecessary energy consumption compared with uncontrolled fixed-speed operation.
The 137H8927 combines a high current and power rating with PROFINET RT communications, extensive standard I/O, integrated STO and dynamic braking capability. Its integrated AC fuses and mains switch further support installation in demanding industrial systems where robust motor control and close integration with machine or process automation are required.
