Why Choose the Original Model
- Proven field reliability — millions of VLT® 2800 units deployed globally across HVAC, conveyor, pump, and fan systems.
- Danfoss ecosystem integration — native compatibility with Danfoss operator panels (LCP), fieldbus options, and parameter backup tools.
- Compact footprint — space-saving design ideal for retrofit and panel-mount installations.
- Established spare parts supply — capacitors, IGBTs, and control cards remain available through specialist distributors.
- Regulatory compliance — CE/UL certified for global deployment without re-certification overhead.
Typical Applications
- Conveyor and material handling systems
- Pump and fan speed control (HVAC, water treatment)
- Compressor soft-start and speed regulation
- Textile and packaging machinery
- Food & beverage processing lines
- General-purpose motor control in OEM equipment
System Compatibility
The VLT® 2800 integrates with the following control architectures and fieldbus networks:
- PLC Brands: Siemens S7, Allen-Bradley ControlLogix/CompactLogix, Mitsubishi MELSEC, Schneider Modicon, Omron CJ/NJ
- Fieldbus / Protocols: Modbus RTU (RS-485), Profibus DP (via option card), DeviceNet (via option card)
- SCADA / HMI: Compatible with standard 4–20 mA / 0–10 V analog setpoint interfaces
- Motor Types: Standard asynchronous induction motors (IE1–IE3); not designed for permanent magnet motors
Selection Guide
Use the following criteria to select the correct VLT® 2800 variant or its replacement:
- Step 1 — Define load type: Constant torque (conveyors, compressors) vs. variable torque (pumps, fans). Variable torque loads may qualify for a smaller drive frame.
- Step 2 — Motor power & voltage: Match drive kW rating ≥ motor nameplate kW. Confirm supply voltage (single-phase 230 V or three-phase 400 V).
- Step 3 — Environment: IP20 for clean panel enclosures; IP55 for dusty or washdown environments.
- Step 4 — Communication: If PLC integration is required, confirm fieldbus option card availability for your protocol.
- Step 5 — Replacement vs. new: For direct swap, match the original part number suffix codes (enclosure, brake chopper, RFI filter). For new installations, consider the FC 51 or FC 302 for longer lifecycle support.
Quality Assurance & Sourcing
- Genuine units: Sourced from authorized Danfoss distributors and verified OEM channels with full traceability.

Replacement & Compatibility FAQ
Q: Is the VLT® 2800 still in production?
A: No. The VLT® 2800 series has been discontinued by Danfoss. The recommended OEM replacement is the VLT® MICRO DRIVE FC 51. Konmask.com stocks both new-old-stock (NOS) and refurbished VLT® 2800 units.
Q: Can I replace a VLT® 2800 with a VLT® FC 51 without rewiring?
A: In most cases, yes. The FC 51 shares similar terminal layouts and parameter structures. Minor wiring adjustments may be needed for analog inputs and relay outputs. Contact us for a wiring comparison sheet.
Q: Will a cross-brand VFD (ABB, Siemens, Mitsubishi) work as a drop-in replacement?
A: Electrically yes, for standard V/f applications. However, Danfoss-specific fieldbus option cards and LCP panels will not be compatible. Reprogramming of PLC communication parameters will be required.
Q: Do you provide a warranty on replacement units?
A: Yes. New genuine units carry the standard Danfoss warranty. Refurbished units carry a 90-day Konmask functional warranty. Extended warranty options are available on request.
Q: Can you supply the full VLT® 2800 series (all power ratings)?
A: We maintain stock across the common power range (0.37 kW – 7.5 kW). For 11 kW and above, lead times apply. Submit your BOM for a bulk quotation.
