Product Description:
The 178B2005 is a variable-frequency drive produced by Danfoss for the VLT 6000 HVAC Drives series. Intended for ventilation, pumping, and chiller applications, it controls induction motors used in building systems. By regulating motor speed in response to operating demands, the drive helps automation systems maintain airflow, pressure, or temperature setpoints while reducing energy use and mechanical stress. This variable-speed operation also limits unnecessary motor output during periods of reduced demand.
Electrical compatibility centers on a mains input range of 380–460 VAC, allowing direct connection to common industrial power supplies without step-down transformers. The inverter section delivers up to 7.5/10 HP, supporting midrange supply fans, return fans, cooling towers, and booster pumps. A slim book-style IP20 housing supports dense control-panel layouts while providing finger-safe protection when the cabinet door is open. Integrated electromagnetic suppression is provided by a Class A1 and B filter, which reduces conducted emissions and helps the drive operate near sensitive control electronics. The model is supplied with no local control panel, so parameter changes require a compatible remote keypad or PC-based tool. This arrangement also prevents casual adjustments from being made at the cabinet front.
The drive is designed specifically for HVAC operation, with predefined fan and pump macros that simplify setup for airflow and pressure control. Its proportional-integral control functions allow the drive to respond directly to changing process demands without requiring a separate controller for basic regulation. The electronics have no protective coating, making the unit appropriate for clean, dry mechanical rooms where condensation and airborne chemicals are not expected. The hardware uses the standard unit configuration, so its power components and signal boards follow the normal operating and derating characteristics for this series. Communication bays and application add-on locations are supplied with no fieldbus or application options. These open locations allow compatible plug-in cards to be installed later if the building control protocol or application requirements change.
