The Danfoss VLT® Midi Drive FC 280 is a highly efficient, mid-range industrial Variable Frequency Drive (VFD) designed specifically to replace legacy motor controllers (such as the classic VLT® 2800) with modern, spacesaving automation. Spanning a versatile power range from 0.5 HP to 30 HP ($0.37\text{ kW}$ to $22\text{ kW}$), this compact drive features dual-channel Safe Torque Off (STO), standard integrated RFI filters, and Active Power Factor Correction (PFC). It is engineered to give machine builders and factory owners the ultimate balance of flexible communication and cost-effective motor control.
The primary function of the Danfoss VLT® Midi Drive FC 280 is to regulate the speed, torque, and overall energy consumption of 3-phase electric motors. By matching motor speeds precisely to real-time machine requirements, it eliminates mechanical stress and cuts electricity waste.
Harmonic Mitigation & Active PFC: Single-phase units utilize Active Power Factor Correction to drop harmonic distortion down to less than 8% THDi. This keeps your shop floor power supply incredibly stable and safe from unexpected transformer trips.
All-in-One Component Savings: Unlike cheap generic inverters, the FC 280 comes with a built-in brake chopper (up to $22\text{ kW}$), integrated DC chokes, and RFI filters. You do not need to spend money on external filter panels.
Universal Motor Compatibility: The advanced control algorithm runs standard asynchronous induction motors as well as modern high-efficiency Permanent Magnet (PM) motors in open loop setups.
Side-by-Side Zero Clearance Mounting: A true compact form factor allows you to pack multiple FC 280 drives tight against each other inside the control panel without any thermal derating or spacing requirements, drastically shrinking panel costs.
State-funded initiatives across Bangladesh—including water treatment facilities (Dhaka WASA), automated packaging divisions of government fertilizer corporations, and handling systems under the Bangladesh Railway—depend heavily on long-lasting automation.
Grid Compliance: Power lines in sub-districts can experience harmonic noise. The integrated DC chokes lower 3-phase harmonics below 48% THDi, keeping government electronics safe.
Built-in Safety Standards: The dual-channel Safe Torque Off (STO) satisfies stringent EN ISO 13849-1 PL d standards, ensuring state-operated plants pass local and international safety audits easily.
Reliable Retrofitting: It is specifically built with matching exterior dimensions to easily swap out dead, obsolete VLT 2800 units in old government plants without rebuilding the entire metal cabinet.
From automated mixing stations in Gazipur’s food processing plants to material handling conveyor systems in Narayanganj’s spinning and RMG hubs, the FC 280 is an industrial workhorse.
High-Temperature Resilience: It operates comfortably at full load in ambient temperatures up to 113°F (45°C), and up to 131°F (55°C) with derating. This is a massive advantage during hot Bangladeshi summers, reducing plant downtime caused by overheating.
Coated PCBs for Longevity: Standard chemically coated circuit boards guard internal components against airborne lint, dust particles, and high relative humidity typical in local textile mills.
Flexible Communication Protocols: Supports a vast array of protocol options right out of the box (PROFINET, Profibus, EtherNet/IP, Modbus RTU), enabling easy linking into existing factory PLCs.

Q1: Can the Danfoss VLT Midi Drive FC 280 replace an old VLT 2800 inverter?
A: Yes, absolutely. The FC 280 is designed as the direct evolutionary upgrade for the iconic VLT 2800. It uses similar software tools, connector layouts, and cable setups to ensure a hassle-free retrofitting process.
Q2: What is the maximum power capacity of the FC 280 available in Bangladesh?
A: The FC 280 series accommodates single-phase input ($200\text{--}240\text{ V}$) up to $2.2\text{ kW}$ (3 HP) and 3-phase input ($380\text{--}480\text{ V}$) starting from $0.37\text{ kW}$ (0.5 HP) up to $22\text{ kW}$ (30 HP).
Q3: Does this drive require external cooling fans inside the electrical cabinet?
A: Generally, no. Thanks to its smart heat sink design, it handles up to 45°C at full industrial load without needing oversized enclosures or supplementary external air conditioners, provided your panel has adequate basic ventilation.
Q4: Is the Safe Torque Off (STO) function standard or an optional add-on?
A: It is built-in as standard. The dual-channel STO eliminates the need for external safety contactors, drastically reducing wiring costs and panel footprint while maximizing operational safety.
Q5: How do I back up or transfer parameters between multiple drives?
A: You can use a standard USB cable hooked up to a PC running the free Danfoss MCT 10 software, or use an optional VLT® Memory Module (MCM 102) to clone configurations across units instantly.
