6-11. Redundant operation disable function
When linking multiple power supplies, it is possible to disable redundant operation so that all units stop when one unit
stops.
Connect the HL to HL terminals and DG to DG terminals between the power supplies.
If even one power supply stops (stops or breaks down), all remaining power supplies will be stopped.
It can also be used for stop protection during series or parallel operation, or when you want to
synchronize the start and stop timing of power supplies.
・Wire to HL terminal, DG terminals shall be as short as possible and same length with twist.
・Redundant operation disable function is possible up to 30 units.
6-12. AUX output
The AUX output voltage is 5V Typ. (4.8 to 5.2V), and the maximum output current is 2A.
The AUX output does not depend on the state of the main output.
AUX output is output even when the main output is in the control OFF state.
Even if the main output is stopped due to a protection function, the AUX will continue to output.
Over Current Protection (OCP) is fold back limit and hiccup mode with automatic recovery.
OCP function operates when the output current exceeds 105% of maximum DC output current of
specification.
The outputs will be automatically recovered when the overload condition is canceled.
Never operate the unit under over current or shorted conditions, which may leads damage or insulation
failure.
Never apply higher voltage externally to the output terminal to avoid unit failure.
In case of inductive load, put protective diode in series to the output power line.
