VLT® Refrigeration Drive FC 103
The VLT® Refrigeration Drive FC 103 covers a power range between 1.1-315 kW. Available in a variety of protection classes the drive suits the needs of pump, fan and compressor applications....
Features and benefits
Refrigeration language
For setting up the drive in the most efficient and logical way, the text and language used make complete sense to refrigeration engineers and installers.
Easy setup with wizard
The built-in “Wizard set-up menu” guides users through the setup of the drive in a clear and structured manner and supports following functionalities:
- Multi compressor control
- Multi condenser and evaporator fan
- Multi condenser and evaporator pumps
Power Range
3 x 200 – 240 V........ 1.1 – 45 kW
3 x 380 – 480 V.........1.1 – 315 kW
3 x 525 – 600 V ....... 1.1 – 90 kW
With 110% overload torque.
•Built for harsh environments
Protection classes
IP 20 (NEMA 1)...... 1.1 – 90 kW
IP 21 (NEMA 1).......1.1 – 315 kW
IP 54 (NEMA 12) .....110 – 315 kW
IP 55 (NEMA 12)..... 1.1 – 90 kW
IP 66 (NEMA 4X)..... 1.1 – 90 kW
Maximum ambient temperature
50˚ C without derating.
Coated electronics
Improved reliability in corrosive and aggressive environments due to protection class 3C2 (EN 60721-3-3) as standard or optionally 3C3.
• Software features
Automatic Energy Optimization
The standard feature AEO provides optimized motor magnetization at all speeds and loads. This increases energy efficiency by 5-15% for partial loads.
Fieldbus
LON for AKD, Modbus RTU. Enables fast and simple connections to overall controller.
Sleep mode
The drive detects when the load is too low and stops the motor. The load can e.g. be air flow or water pressure.
Day/night control
In day/night control mode the application runs normally during the day, while running with an increased set-point during night time.

Features and benefits
Integrated DC link harmonic filters
Standard feature in the drive that enables low harmonic load on the network within EN 61000-3-12 limits.
Integrated EMC filters
Eliminates the need for external filters. The selected filter class will be included in the drive.
• Compressor features
PO optimization
Supports the ADAP-KOOL P0 Optimisation feature, which enables automatic adaptation of the suction pressure to match the system’s actual load optimally.
Injection on/off
Control of injection valves for start with reduced load.
Discharge temperature monitor
Monitors the discharge temperatures and prevents that they reach dangerous levels.
Pack controller
Operates one compressor with variable speed. Additional compressors are turned on/off based on the load situation.
Neutral zone controller
Enables handling of asymmetrical zones.
Thermostat/Pressostat function
Performs compressor start/stop when running in closed loop, based on pressure and temperature feedback.
• Pump features
Dry pump protection & end of curve
Constantly evaluates the condition of the pump (e.g. breaks and leakage) and reacts as desired.
Flow compensation
Compensates for negative effects which can arise when the pressure sensor is located close to the pump or fan.
Pressure-to-flow conversion
The drives converts the signal from the pressure transmitter to the flow value.
• Fan features
Broken belt detection
Stops the motor automatically when a broken belt is detected.
Operate induction motors in parallel
Use one drdive to control several motors in parallel .
