Key Features

1. Energy Efficiency:
   • The VLT® FC 302 incorporates Danfoss’s Energy Saver function, which optimizes motor speed to reduce energy consumption by up to 30% in variable torque loads (e.g., fans, pumps).
   • Automatic sleep/wake modes minimize standby power losses.
2. Advanced Control:
   • Sensorless Vector Control (SVC) provides precise speed and torque regulation, critical for applications requiring dynamic responses.
   • Built-in PID controller simplifies process automation, such as pressure or temperature regulation.
3. Connectivity:
   • Standard Modbus RTU and BACnet protocols enable seamless integration with building management systems (BMS).
   • Optional Profibus DP and Ethernet/IP modules support Industry 4.0 applications.
4. Safety:
   • Safe Torque Off (STO) function (EN 61800-5-2) ensures rapid motor shutdown in emergencies.
   • Overcurrent, overvoltage, and thermal protection safeguard both the drive and motor.

Applications

The VLT® FC 302 Series excels in diverse industries, including:

1. HVAC Systems:
   • Variable air volume (VAV) control in fans and blowers.
   • Precision temperature regulation for chillers and heat pumps.
2. Water/Wastewater:
   • Pump control for constant pressure or flow optimization.
   • Reduced energy costs in municipal and industrial water networks.
3. Material Handling:
   • Conveyor belts and elevators requiring smooth acceleration/deceleration.
4. Food & Beverage:
   • Mixer, agitator, and refrigeration unit motor control.

Installation & Operation

Installation

• Mounting: Wall-mounted or side-by-side configurations (minimum spacing: 50 mm).
• Wiring:
  • Power terminals (L1, L2, L3) and motor terminals (U, V, W) support cable cross-sections up to 2.5 mm².
  • Control terminals include digital inputs/outputs, analog signals (0–10 V, 4–20 mA), and relay contacts.
