Product Description:
The 178B2742 is an AC variable frequency drive manufactured by Danfoss and supplied within the VLT 2800 Low Voltage Drives series. The unit converts fixed-frequency line power into a modulated output so that PLCs or stand-alone controllers can regulate induction motor speed in conveyors, pumps, and general process machinery. By varying frequency and voltage, it supports energy-efficient torque control in industrial automation applications that require a compact panel depth and straightforward setup.
This model delivers a continuous output of 1.5 kW, equivalent to 2.0 HP, giving it enough capacity for small to medium fans or agitators. It accepts line supplies of 380–480 V ±10% at 50/60 Hz, allowing installation on common European or North American distribution systems without a transformer. The power section uses a three-phase input, which balances current draw and reduces the required conductor size compared with single-phase equipment. A built-in rectifier and IGBT inverter produce an adjustable output while maintaining compatibility with motor insulation limits. The drive has an ingress protection rating of IP20, so it must be installed inside a control cabinet but does not require an additional gasketed enclosure for basic indoor environments.
The drive uses a book-style format, allowing multiple units to be mounted edge-to-edge in shallow enclosures to conserve panel width. Conducted emissions are limited by an integrated RFI filter that meets EN 55011 Class A1, helping facilities satisfy electromagnetic compatibility requirements at industrial sites. The drive has no optional application card, so it operates in its default control mode without specialized HVAC, winder, or positioning extensions. It is intended for process applications, with default parameters suited to constant-torque loads commonly found in mixers, extruders, and dosing equipment. The electronics are supplied without a protective coating, allowing conventional heat dissipation through the finned aluminum chassis while requiring suitable protection from moisture and airborne contaminants inside the cabinet.
