Product Description
Rated at 1.1 kW (1.5 HP) with a 380-480 V three-phase supply, it drives three-phase induction motors with U/f and process control. This configuration (FCD311PT4P66EBR1DCF10T62C0) includes a 24 V DC external supply with brake chopper and mechanical brake control (EB), a class A1 RFI filter (R1), a mounted LCP display connector (DC), Profibus DP fieldbus (F10) and a double-side wall-mount installation box with service switch (T62). It suits food and beverage, automotive and material handling lines where drives must survive frequent cleaning. The Danfoss VLT FCD 311 is a decentralized frequency converter from the VLT FCD 300 series, built for IP66 / NEMA 4X mounting directly on or beside the motor in harsh, washdown environments.
Basic Product Information
- 1.1 kW (1.5 HP) rated output for 380-480 V three-phase mains
- Integrated 24 V DC external supply with brake chopper and mechanical brake control (EB variant)
- Integral class A1 RFI filter and intermediate-circuit coils for reduced harmonic input current
- Built-in Profibus DP fieldbus (F10) plus RS-485 FC and Prodrive protocols for system integration
- Mountable LCP display connector (DC) with 5 status indicator lamps
- Decentralized IP66 / NEMA 4X enclosure allows motor-mount or wall-mount installation close to the driven equipment
Technical Specifications
Version & Model Difference
The FCD 311 belongs to the VLT FCD 300 series of decentralized drives. The 311 power size sits between the FCD 307 (0.75 kW) and the FCD 315 (1.5 kW). The 'P' application range denotes process use, 'T4' the 380-480 V three-phase mains, and 'EB' adds a 24 V external supply with brake chopper and mechanical brake control. A brake resistor must be ordered separately where dynamic braking is required.
