SR250HL Series - 250 W Power Supply/Float Charger for Lead Acid Ba$eries
6. N+1 REDUNDANCY
Two or more SRxxxHL series power supplies may be connected in parallel for increased power or redundancy (with or without di-
odes). It is essenEal that the wiring from each unit to the load is kept idenEcal for equal power sharing parEcularly when diodes are
not used.
Note that the communicaEons will stop on mains or converter fail if no baDeries are used on the output.
7. CONNECTION NOTES
•
Two outputs connected in parallel internally are provided.
•
If used as a baDery charger ensure that the baDery polarity matches the power supply output.
•
Alarms can be tested by using an external variable voltage supply.
