What is the difference between ACE949 and ACE949-2?
Issue:
Clarifying the differences between ACE949 and ACE949-2 communication modules for Sepam systems.
Product:
ACE949
ACE949-2
SEPAM 20
SEPAM 40
SEPAM 60
SEPAM 80
Environment:
Sepam protection relays using RS485 Modbus communication with distributed power supply.
Cause:
Users need to understand the power supply specifications and their impact on system design and communication line length.
Resolution:
The difference between ACE949 and ACE949-2 lies in the distributed power supply level transmitted over each SEPAM in parallel with the RS485 Modbus line:
-
- ACE949: 12 V DC
- ACE949-2: 12 V DC or 24 V DC
- Using 24 V DC increases the maximum length of the distributed power supply line, providing greater flexibility for installations requiring longer distances.
