Product Description:
The 178B3440 is a low-voltage AC drive manufactured by Danfoss and supplied within the VLT 2800 Low Voltage Drives series. It converts fixed-frequency utility power into a variable-frequency output that regulates induction motor speed, torque, and direction for conveyors, mixers, and other continuous-duty equipment. Integrated current limiting, ramp functions, and status diagnostics support controlled operation in process automation while helping protect the motor and connected machinery from sudden changes in speed or load.
The drive connects to a single-phase utility supply rated at 200–240 V AC, allowing installation in facilities without three-phase service. Its topology uses a single-phase input, so only two line conductors and a protective earth connection are required. A built-in display (SLCP) on the front panel shows output frequency, current, operating status, and alarm codes, which makes essential information available directly at the drive. Network integration is provided by the factory-installed DeviceNet interface, enabling remote commands and data exchange through a CAN-based PLC network. The IP20 enclosure helps prevent accidental finger contact with live components while permitting the airflow required for thermal dissipation inside a suitable control cabinet.
The narrow book-style housing permits dense side-by-side mounting without increasing the required cabinet depth. The model uses the standard hardware configuration, so auxiliary relays, filters, and extended input and output functions are not preinstalled but may be connected externally when required by the application. Because the drive has uncoated electronics, it should be installed in a clean, dry location that limits exposure to condensation, conductive dust, chemical vapors, and other airborne contaminants. The unit is configured for process applications, with parameter defaults suited to flow and pressure control where smooth speed variation is favored over constant-horsepower operation. Its compact format also leaves room for appropriate cable routing and ventilation clearances within the enclosure.
