Mounting and output planning
Use the datasheet’s installation arrangement, including a suitable aluminum plate or cabinet surface and at least 5cm clearance around the supply. Low-input operation can reduce available current. For a 5V system, check cable voltage drop and terminal connections as well as the total load.
Frequently Asked Questions
Is HSP-300-5 rated at 5V 60A?
Yes. Its rated output is 5V, 60A and 300W under the specified conditions.
Is the AC input one continuous 90–264V range?
The linked specification lists 90–135VAC or 180–264VAC. Use these stated ranges and the static-characteristic curves for the installed revision.
Can it deliver full output at every input voltage and temperature?
No. The datasheet includes input-voltage and temperature derating curves. Check both for the intended installation.
Does HSP-300-5 have active PFC?
Yes. Active power factor correction is listed for this model series.
What cooling arrangement is required?
The supply uses convection cooling and must be mounted to the specified heat-transfer surface. The PDF includes the aluminum-plate dimensions and clearance instructions.
