FAQ

Q: What is the difference between standalone and summable mode?
A: In standalone mode, the module powers a single rack independently. In summable mode, multiple power supplies can be combined to increase total output current capacity.

Q: Does the module include output protection?
A: Yes, internal overvoltage and overload protection circuits are integrated.

Q: What voltage does the module supply to the PLC rack?
A: It delivers a regulated 5.1 V DC output for the Quantum backplane.
