FAQ
Questions before quotation
Is Common Cathode Display Series suitable for my project?
It is a good candidate for energy-aware LED displays, fine-pitch screens, indoor media walls, and long-running display installations. Share the load voltage, power, installation space, and working environment so the model can be matched more accurately.
How much power reserve should I leave?
Most projects should avoid running the supply at its absolute limit. The right reserve depends on heat, enclosure ventilation, startup current, and daily operating time.
Can SPR help replace an existing power supply?
Yes. Send the old label, output rating, size, wiring photo, and application. The team can recommend a suitable display power solution for screen-side loads with a similar installation direction.
