Input and thermal checks
The linked specification lists two AC input ranges. Use those ranges rather than interpreting the general “universal input” description as a continuous rating across the gap. Review the static-characteristic and derating curves for the planned operating point.
Allow ventilation around the enclosure and compare mounting and terminal positions against the PDF. Conformal coating is not a waterproof enclosure rating. Check the final equipment’s environmental and EMC requirements during integration.
Frequently asked questions
What is the rated output of the HSP-300-5?
The datasheet specifies 5V DC, 60A and 300W with convection cooling.
Does it include active PFC?
Yes. Typical full-load power factor is at least 0.93 at 230VAC and at least 0.98 at 115VAC under the stated conditions.
What AC input ranges are specified?
The linked datasheet lists 90–135VAC or 180–264VAC. Check the static characteristics for operation within those ranges.
Does the HSP-300-5 need an internal fan?
It uses free-air convection cooling. The installation must still provide the mounting and thermal conditions required by the datasheet.
