Product Description:

The 175Z4105 is a frequency converter manufactured by Danfoss within the VLT 5000 Frequency Converters series. Designed for panel integration, the device regulates the speed of standard three-phase motors so that pumps, fans, and conveyors can follow process commands rather than run at a fixed synchronous speed. By modulating output frequency and voltage, it provides closed-loop torque control that aligns the motor load with process demand, supporting lower energy consumption and smoother mechanical acceleration in industrial automation lines.

The drive operates from a 380–500 V three-phase supply, allowing direct connection to common industrial mains without step-down transformers. The inverter provides 15 kW at a 110% overload level, supporting applications that require a moderate torque margin. The electronics are protected by a compact IP54 enclosure that blocks dust ingress and resists water splashes, allowing the unit to be installed closer to the machine. Control functions reside on a process control card, providing proportional speed regulation through analog or digital references. Conducted emissions are reduced by the integrated Class A1 and Class B filter, which limits high-frequency electrical noise transmitted through the supply lines.

For high-demand startups, the unit supplies 11 kW at 160% torque for a short operating period, helping prevent nuisance trips when loads accelerate quickly. A front-mounted supplied display enables parameter entry, fault viewing, and on-site performance checks without requiring external tools. The drive uses uncoated circuit boards, so it must be installed in an area that remains free of corrosive gases, conductive dust, and excessive moisture. The unit has no fieldbus option, so serial or Ethernet communication must be handled through an external gateway when the control system requires network connectivity.
