Can Belimo NF-24SR Actuator Share Transformer with DMS MSC-MPC Controller?

[Product_Support]

Issue

Can a Belimo damper actuator (e.g., NF-24SR) be powered from the same transformer as a DMS MSC-MPC Microsmart controller?

Product Line

TAC IA Series

Environment

• Belimo damper actuator
• DMS MSC-MPC (Microsmart controller)

Cause

The MSC-MPC controller uses full-wave rectification, while Belimo actuators use half-wave rectification. Sharing the same transformer introduces electrical incompatibility, which can lead to component-level damage in the MSC-MPC controller.

Resolution

• Do not share the same transformer between MSC-MPC controllers and Belimo actuators.
• Provide separate power supplies for each device to prevent electrical interference and potential damage.
