Product Analysis: 130B1108 VLT® 24V DC Supply MCB 107
The Danfoss 130B1108 is a critical option module known as the MCB 107 24V DC Supply. It is designed to be installed within the VLT® Series drives (specifically compatible with the VLT® HVAC Drive FC 102, FC 103, and FC 300 series). This module enables the connection of an external 24V DC power source to keep the drive’s control electronics active even when the main AC power supply fails.
Functionality and Benefits
- Backup Power: Keeps the Control Card, LCP, and fieldbus communication alive during mains loss.
- Compatibility: VLT® HVAC FC 102, Refrigeration FC 103, AutomationDrive FC 301/302.
- Input Voltage: 24 V DC (External).
- Module Type: D-Option (Mounts in the dedicated slot).
- Version: Uncoated PCB.
Critical Application Use
Using the MCB 107 is essential in critical automation systems where continuous monitoring is required. By maintaining power to the control card, the drive can continue to communicate its status to the BMS or PLC, log alarms, and ensure a faster restart once mains power is restored (as the control electronics do not need to reboot). It is particularly useful in HVAC and refrigeration systems where maintaining visibility of system status is a safety priority.
