Product Description:

The 175Z4883 is an AC variable frequency drive manufactured by Danfoss for the VLT 6000 HVAC Drives series. It is intended for heating, ventilation, and air conditioning systems in which fan or pump speed must respond to changing load demand. By modulating the voltage and frequency supplied to an induction motor, the drive provides energy-efficient flow control and reduces mechanical wear in building automation equipment. Within a plant control network, the unit can operate as a standalone regulator or receive analog set points from a supervisory controller.

The drive accepts a three-phase input of 380–460 VAC, enabling direct connection to common industrial power systems. Its continuous output capacity reaches 55 kW / 75 HP, supporting large air handlers and primary chilled-water pumps. The equipment is packaged in a compact IP54 enclosure that protects internal components against dust and splashing water, allowing installation in suitable mechanical rooms without a separate cabinet. An integrated electromagnetic interference filter rated for Class A1 and B controls conducted emissions on the supply conductors. Parameters are adjusted through an included LCP, and the detachable control panel displays speed, current, operating information, and fault codes at the installation site.

The drive is supplied as a standard unit that uses the common configuration for this VLT 6000 model. Its control boards have no protective coating, so the installation area must be kept free of excessive moisture, corrosive vapors, and airborne contaminants that could affect exposed electronics. The factory configuration is supplied without a fieldbus interface, while the built-in RS-485 connection can support compatible serial communication when required by the control system. The drive also comes without application option modules, including dedicated pressure-control or pump-cascade expansion hardware. General HVAC control remains available through the drive’s standard inputs, outputs, motor-control functions, and local control panel.
