MQ200PC5A supply: specification comparison and installation
The Rong-Electric MQ200PC5A is an LED display power supply with a nominal 5 V DC output, natural cooling and a required auxiliary heat-dissipation plate. The original overview identifies undervoltage, current-limit and short-circuit protection.
Rating discrepancy: the original page table and model-matched PDF disagree on output power/current, input range and ripple limit. The table below keeps those sources separate. Additional technical entries come from the PDF; confirm the actual unit label and revision before using either set of conflicting ratings.
Technical specifications

Frequently asked questions
Is MQ200PC5A a 200 W or 300 W supply?
The linked MQ200PC5A PDF explicitly specifies 200 W and 0–40 A at 5 V. The original page table instead listed 300 W and 0–60 A. These values conflict; verify the unit label and hardware revision before selecting a replacement or applying the higher load.
What input voltage should be checked?
The model-specific PDF input table states 176–264 V AC, with 200–240 V AC rated input. The original page gave 160–264 under a Vdc heading, and the PDF graph starts at 170 V AC. Do not combine these into an expanded operating range.
Does the MQ200PC5A need a heat-dissipation plate?
Yes. Both the original environmental table and PDF specify a 200 × 200 × 3 mm auxiliary plate under the supply. The installation must also account for the cabinet temperature.
Can it run at full load at 70°C?
No. The temperature curve reduces load above 50°C and reaches 75% at 70°C. Use that curve with the confirmed unit rating and the required heat-dissipation plate.
Where can I find the original specification and terminal layout?
The original specification link remains below the product image. The PDF includes the input/output connector definitions and mounting drawing; its identified rating differences are documented on this page for checking against the actual unit.
