MQ300PC5H power supply for 5 V LED display loads
The Rong-Electric MQ300PC5H supplies a nominal 5 V DC output for LED display systems. Its documented output range is 0–60 A, with a 300 W rating, output current limiting and short-circuit protection.
Plan the load using the model-specific input and temperature curves. Full output is not specified across every input-voltage and temperature combination. The PDF input section explicitly states AC, although its summary-table heading says Vdc; its temperature graph also extends beyond the environmental-table limit. These source differences are identified below without expanding the stated rating.

Frequently asked questions
Can MQ300PC5H run from a 110 V AC supply?
The model-specific input table gives 160–264 V AC at 50/60 Hz, so 110 V AC is outside the documented range. The summary table uses a Vdc label, but section 5.1, input-frequency entry and derating graph explicitly specify AC.
Is the full 300 W available at 160 V AC?
No. The input-voltage curve specifies 80% load at 160 V AC, 90% at 170 V AC and 100% from 180 V AC upward. Temperature derating and the actual cabinet conditions must also be considered.
Does it deliver full output at 60°C?
The temperature curve falls from 100% at 50°C to 75% at 60°C. The environmental table limits operation to +60°C even though the graph continues to 70°C; do not use that graph extension alone to claim an approved +70°C operating range.
How are the AC and DC terminals arranged?
Facing the connectors from left to right, the PDF defines CON1 as N, N, L, L and earth; CON2 is three GND terminals followed by three +5 V terminals. Verify the markings on the actual unit and follow the connector diagram for installation.
Does the 72–90 A protection threshold increase the 60 A rating?
No. 0–60 A is the specified output-current range. The 72–90 A figure is the overcurrent-protection threshold, with hiccup and automatic recovery, not an additional continuous output rating.
