Product Description:

The 175Z4151 is an AC frequency converter produced by Danfoss for the VLT 5000 Frequency Converters series. The unit transforms fixed mains frequency into a variable output that allows induction motors to match process demand in automated machinery. Its product type is VLT 5000. By adjusting motor speed without mechanical throttling, the converter helps reduce energy use and simplifies torque regulation in conveyor lines, pumps, and fans.

The drive is enclosed in a Compact IP20 frame, so it is intended for installation inside a cabinet where basic finger protection is sufficient. The input section accepts a 380–500 V three-phase supply, providing compatibility with industrial mains. For applications that require temporary torque peaks, the inverter can deliver 30 kW at 110% overload. The drive is supplied standard with a brake chopper, allowing regenerated energy to be dissipated instead of returning to the bus. A process control card handles feedback and setpoint processing, enabling proportional speed regulation from external controllers. A detachable display provides local access to parameters and real-time operating status.

The continuous power available when higher dynamic torque is required reaches 22 kW at the 160% torque point, providing a second sizing reference below the short-term 30 kW limit. Electronic assemblies use non-coated circuit boards, so the drive should be installed in locations free from conductive dust and corrosive vapors. The drive has no built-in application module, leaving the available input and output connections open for external fieldbus or sensor wiring. It also has no integrated RFI filter, so compliance with local electromagnetic interference limits requires an external filter mounted in the same panel. Proper cabinet placement should provide adequate separation from contamination sources and enough room for the required external filtering components.
