Internal Product Review

The 175Z0318 is a Danfoss VLT 5000 frequency converter with a process control card for dependable drive regulation. Standard brake chopper hardware and 380-500 V three-phase supply make the converter well suited for demanding process applications. A compact IP54 enclosure adds practical installation value and rounds out a well-engineered converter.

Product Description:

The 175Z0318 is a variable-speed drive manufactured by Danfoss and supplied within the VLT 5000 Frequency Converters series. The unit converts fixed-frequency three-phase power into a controllable output waveform, allowing automated machinery to regulate induction motor speed for pumps, fans, and material-handling equipment. This variable output helps maintain stable process conditions as operating demand changes. It can also reduce unnecessary energy consumption when connected equipment does not need to run continuously at full speed.

The drive accepts a 380–500 V three-phase supply, allowing it to connect to common industrial distribution networks without an external transformer. When the operating profile requires only 110% overload capacity, it can deliver 11 kW continuously. Heavy-duty cycles that require 160% torque are supported at 7.5 kW. A built-in standard brake chopper channels regenerative energy produced during rapid deceleration into a dissipation circuit, helping limit disturbances on the incoming power lines. The power stack is housed in a compact IP54 enclosure, which protects live components against airborne dust and incidental water spray. The drive has no built-in application option or installed fieldbus option, leaving its control arrangement suitable for standalone speed regulation through conventional connections.

System interaction is coordinated by a process control card that provides analog and digital terminals for remote starting, speed references, and fault signaling. A factory-installed front-mounted display provides direct access to parameters and real-time operating information without requiring separate display equipment. The unit uses non-coated circuit boards, so it should be installed where moisture, conductive dust, and corrosive airborne contaminants remain controlled. Electromagnetic compatibility is supported by a Class A1 filter, which attenuates conducted emissions on the main power lines. Local display access allows operating values and fault conditions to be reviewed directly at the enclosure, while the available control terminals support connection to external switches, sensors, and automation signals.
