Product Description:
The 134U7748 is an AC variable frequency drive produced by Danfoss as part of the VLT FC 280 Midi Drives series. The device belongs to the 280 subfamily and is intended to modulate the speed of three-phase induction motors used in automated machinery. By varying the output frequency and voltage, the drive allows process equipment such as conveyors, pumps, and small material-handling stations to match load requirements, conserve energy, and reduce mechanical stress. In factory-floor installations, it occupies less panel depth than earlier VLT models while providing the basic motion functions required for decentralized automation systems.
The unit delivers continuous motor power of 2.2 kW and operates from a three-phase 380–480 VAC supply. The chassis has an IP20 chassis rating, so live parts are protected against finger contact, but the drive must be installed inside an enclosure that provides adequate protection from dust and moisture. Conducted radio-frequency noise is attenuated by the built-in EMC Category C3 filter for 200/400 V systems, supporting compliance with industrial electromagnetic compatibility limits without requiring an external filter. For plant networks, the factory-installed integrated PROFIBUS DP interface transmits setpoints, receives feedback, and supports remote parameter transfer, reducing separate wiring and simplifying drive setup.
A built-in brake chopper dissipates regenerated energy, enabling quick stops with moderate-inertia loads without requiring the mains supply to absorb all returned energy. The power section uses a coated printed circuit board to resist condensation and airborne contaminants that are common in humid production areas. For applications using imperial output units, the drive provides an equivalent motor output of 3.0 HP, making it suitable for compact pump, fan, and conveyor duties. The control cover is supplied with no display, so parameter adjustments and operating commands must be handled through the fieldbus connection or compatible PC tools. Both adaptation fields are set to no adaptation, leaving the standard product configuration unchanged.
