Planning the display load
Use the electrical requirements of the actual LED modules when sizing a cabinet. A module count cannot be established from the model name or output current alone. Check the intended load and operating conditions before deciding how many modules to connect.
The listing identifies input undervoltage, overload and short-circuit protection, together with ventilation cooling. It does not supply dimensions, a temperature derating curve or protection thresholds. Confirm those details when evaluating a replacement or a new cabinet layout.

Frequently asked questions
What output does the MQ300PC4.5 provide?
The listing specifies a 4.5 V DC output and 60 A output current for LED display applications. Match the module voltage and the display load before selection.
Does the MQ300PC4.5 support 110 V and 220 V mains?
Both are within the listed 100–240 V AC input range. The product information states compatibility with 50 Hz and 60 Hz input.
Does 5.0 A refer to the AC input or DC output?
The 5.0 A value is the listed maximum input current. The output current is listed separately as 60 A at 4.5 V DC.
How many LED modules can one supply power?
A fixed module count cannot be determined from the supply rating alone. It depends on each module’s voltage and load, the display operating conditions and the permitted supply loading. Confirm these values for the actual modules before sizing the installation.
What should I check when replacing an existing supply?
Check the full model, AC input, DC output, required current, mounting holes and terminal arrangement. Dimensions and thermal derating are not provided in this listing, so confirm them for the replacement unit.
