Product Description:
The 175Z4881 is an AC variable-frequency drive manufactured by Danfoss for the VLT 6000 HVAC Drives series. It converts fixed three-phase mains power into a modulated output that lets building-management controllers regulate the speed of fans, pumps, and compressors used in climate-control loops. Installed inside an automation panel, the drive acts as the final power stage that receives analog or digital setpoints and delivers precise torque to induction motors without mechanical throttling, improving energy use in air-handling units, cooling towers, and chilled-water circuits.
The drive has a continuous power rating of 55 kW/75 HP, enabling operation of large blower wheels or multi-pump arrays without derating. The input section accepts three-phase supplies from 380–460 VAC, covering common 400 V distribution networks. All components are housed in a compact IP20 enclosure that relies on airflow within the cabinet for heat removal. Operators program setpoints through the detachable keypad and included LCP, which displays parameters, alarms, and real-time values. Conducted emissions are attenuated by an integrated Class A1 and B filter, helping the system meet applicable electromagnetic compatibility requirements without an external filter.
The control features are designed for HVAC service, including the regulation of centrifugal fans and variable-torque pumps. The drive is supplied as a standard unit with the baseline functions needed for these applications. Its uncoated circuit boards are intended for indoor electrical cabinets where humidity and airborne contaminants are controlled. The fieldbus slot and application option port have no installed option cards, so external supervisory equipment communicates through conventional analog references or relay logic connected to the terminal strip. This arrangement supports direct integration with standard building controls while leaving the dedicated option ports physically available.
