Delta DPSN-300DB Electronics power supplies Power Supply

The Delta DPSN-300DB is a 300W switch mode power supply module from Delta Electronics, built as an original equipment supply for Nortel networking hardware of its generation. Delta manufactured power modules to the host vendor’s mechanical and electrical specification, so the unit is keyed to a particular chassis bay and backplane connector rather than being a general purpose supply. That is the detail worth checking before ordering, because the DPSN and DPS families cover a wide spread of output rails and formats. The rating label on the module itself carries the definitive output figures, and that is what we check against a requirement. Supplies are among the first components to age in equipment of this vintage, so replacements are a routine part of keeping a working chassis in service. Tech-Star is UK based and ships worldwide.
