MA300SH5 Rong power supply for LED displays
The Rong-Electric MA300SH5 is a single-output, constant-voltage LED power supply listed at 5V, 60A and 300W. It has a rated 200–240VAC input and uses forced cooling. The original listing gives dimensions of 190 × 82 × 30mm.
For replacement work, compare the exact model, electrical ratings and cabinet fit. The linked specification adds an important thermal condition: an additional heat-dissipation plate is required at 60°C ambient.

Cooling and specification checks
Keep the fan airflow path clear in the LED cabinet. The original −30 to +60°C temperature statement does not include the PDF’s added-plate condition at 60°C. Confirm the installation arrangement for the supplied version before relying on operation at that ambient temperature.
The original 88% efficiency statement and the PDF’s ≥86% value use different wording; only the PDF value includes the stated 220VAC, full-load and room-temperature conditions. The PDF input table rates the unit at 200–240VAC; its explanatory note also mentions 180–264VAC. Confirm any use outside the rated range against the matching unit specification.
Frequently asked questions
What is the MA300SH5 Rong power supply used for?
The MA300SH5 is a single-output, constant-voltage Rong-Electric power supply listed for LED displays, with a 5V output, 60A rating and 300W output power. Match the LED modules and cabinet load to the supplied unit.
Can the MA300SH5 run on 110V AC?
Its rated input is 200–240VAC. 110VAC is outside this range and should not be assumed compatible.
Does the MA300SH5 need a fan or an extra heat-dissipation plate?
The PDF specifies fan-forced air cooling. It lists −30 to +50°C operation and adds that a heat-dissipation plate is required at 60°C ambient. Confirm the plate arrangement and supplied version before designing for that condition.
Is its efficiency 88% or 86%?
The original listing states 88%. The linked V1.0 PDF specifies at least 86% at 220VAC, full load and room temperature. These source values are retained separately; confirm the applicable revision and test conditions for the unit you order.
What should I check when replacing an MA300SH5?
Check the exact model, 200–240VAC input, 5V/60A output, listed 190 × 82 × 30mm dimensions, mounting holes, terminal positions and fan clearance. Confirm the applicable thermal conditions before using it in an existing cabinet.
