FAQ – Common Questions
What_is_the_function: It provides ORing and redundancy for parallel 24 VDC power supplies.
Can_it_be_hot_swapped: No, the DC branch must be de‑energized before replacement.
Does_it_regulate_voltage: No, it only performs ORing and redundancy; regulation is done by upstream supplies.
What_is_the_output_rating: 20 A and 480 W maximum.
Where_is_it_used: PLC systems, safety controllers, and redundant DC networks.
