Product Description:
The 178B2002 variable frequency drive is manufactured by Danfoss and supplied through the VLT 6000 HVAC Drives series. The device modulates the speed of induction motors that run centrifugal fans, circulation pumps, and exhaust blowers in building automation systems. By converting fixed mains power into a variable output frequency, it allows the building control system to match air volume or water flow to real-time demand. This adjustable operation can reduce energy use in ventilation and chiller loops when full motor speed is not required.
Input power for the drive can be taken from a three-phase network rated at 380–460 VAC. Internally, the supply is rectified and inverted to produce a variable output with a continuous motor rating of 2.2 kW (3 HP), making the drive suitable for small to midsize air-moving equipment. The electronics are housed in a compact book-style IP20 enclosure, which limits mounting depth and supports unobstructed cabinet airflow while providing basic protection against accidental contact. Conducted emissions are controlled by an integrated Class A1 and Class B filter, allowing the unit to share switchboards with sensitive building management controllers while meeting applicable electromagnetic compatibility requirements. The narrow housing also supports installation in electrical cabinets where available panel space is limited.
The model is supplied without a local control panel, so parameter entry and local start-stop commands require a compatible remote keypad or supervisory network. Its core electronics are configured as a standard unit, and the terminal set provides the customary analog references and digital inputs and outputs used with air-handling equipment. The drive uses uncoated circuit boards, so it should be installed in a clean electrical room without excessive moisture or chemical vapors. Controls for HVAC applications include predefined fan and pump macros that simplify setup for common building systems. The fieldbus slot and dedicated application bay have no factory-installed options, preserving capacity for compatible BACnet, LonWorks, or additional input and output cards if future project requirements call for expanded communication or control functions.
