Product Description:
The 178B2008 is an AC variable frequency drive manufactured by Danfoss for the VLT 6000 HVAC Drives series. It regulates fan and pump motors in building climate systems, allowing automation controllers to match airflow or water circulation to changing demand. By varying the motor supply frequency and voltage, the drive supports efficient control of ventilation, heating, and cooling equipment in large facilities.
The drive connects to a three-phase mains supply rated at 380–460 VAC. Its inverter section supports a continuous mechanical output of 4.0 kW or 5.0 HP, making it suitable for moderate-capacity fans and pumps. Cooling air passes through the spine of the slim book-style IP20 enclosure, allowing compact installation inside a protective electrical panel without additional ductwork. Integrated mains suppression is provided by a Class A1 and B filter, which limits high-frequency emissions on industrial and residential supply networks. The drive is supplied with no local control panel, so settings must be adjusted through a remote interface or a compatible plug-in panel. Its uncoated power and control boards are intended for conditioned switchrooms where excessive moisture and corrosive airborne contaminants are not expected. Adequate panel ventilation should be maintained so cooling air can move freely through the enclosure and carry heat away from the internal power components.
The functional profile is configured for HVAC duty, providing operating behavior suited to variable-torque loads such as centrifugal fans and pumps. The drive includes no factory-installed option cards, so communication gateways, pressure transducers, and other control accessories can be selected separately for the application. Core electronics follow the standard unit configuration, with the baseline parameter menus and input/output terminals used by the VLT 6000 platform. External automation equipment can issue speed references and operating commands based on temperature, pressure, flow, or occupancy signals. This arrangement allows the drive to respond to building-control demands while keeping motor operation aligned with the required airflow or water-circulation level.
