Product Description:
The 178B2106 is an AC drive produced by Danfoss for the VLT 6000 HVAC Drives series. It is intended for variable-speed control of fan and pump motors in building automation systems. By modulating its output frequency, the drive provides energy-efficient airflow or water circulation that matches real-time demand in air-handling units, cooling towers, and hydronic loops. This control method can reduce unnecessary motor operation when a system requires less than its maximum flow rate.
This model delivers a continuous mechanical output of 30 kW / 40 HP, allowing it to accelerate and regulate medium-sized induction motors. A three-phase supply range of 380–460 VAC lets the drive connect directly to common North American and international power systems. The Compact NEMA 1 enclosure protects live parts from incidental contact while maintaining a shallow profile for crowded mechanical rooms. Network integration is available through the embedded LonWorks free-topology interface, which enables peer-to-peer communication with building management controllers over unshielded twisted-pair wiring. For local startup and parameter changes, the unit includes a Local Control Panel (LCP) with a backlit display, menu keys, and a handheld copy function. The copy function allows settings to be transferred between identical drives without entering each parameter manually.
The drive has no integrated radio-frequency filter, so external electromagnetic compatibility measures may be necessary when sensitive instrumentation is nearby. Its uncoated power board is suitable for clean, conditioned spaces rather than corrosive or high-humidity areas. The internal design uses a standard unit configuration, keeping the input and output arrangement and cooling layout consistent with regular production models. The application descriptor is set to Graham for the designated HVAC control sequences. This application assignment supports operation with the associated building automation arrangement without introducing unrelated control functions.
