CHECK BEFORE YOU CHOOSE
Select the PSU Around the Actual Load
A higher current rating alone does not make a power supply the right fit for every cabinet.
01
Voltage & Compatibility
- Confirm the required DC voltage from the equipment label.
- Check the PSU model, output ratings and terminal layout.
- Match replacement dimensions and mounting provisions.
02
Load & Distribution
- Provide module quantity and documented power demand.
- Allow for the manufacturer’s operating and derating limits.
- Have the cabinet’s distribution and protection reviewed.
03
Cooling & Environment
- Check ventilation, cabinet temperature and clearance.
- Confirm enclosure suitability for the installation site.
- Include service access and installation conditions.
Important: Mains wiring, earthing, protection and PSU installation must be handled by a qualified technician. Isolate power before inspection or servicing; do not work on exposed live terminals.
PLANNED AROUND YOUR PROJECT
Power Planning for the Complete Cabinet
Match the parts, installation conditions and support scope to your actual LED system.
Indoor LED Screens
Match module load and cabinet ventilation for everyday display operation.
Outdoor Cabinets
Review the protective enclosure and site conditions; an outdoor screen does not make every PSU weatherproof.
Replacement & Maintenance
Check the old PSU label and failure symptoms before selecting a compatible replacement.

YOUR QUESTIONS, ANSWERED
FAQs About LED Power Supplies
Practical answers about selection, compatibility and project support.
01How do I choose the correct LED power supply?
Confirm the required output voltage, documented load, operating temperature, enclosure and mounting requirements. A technician should check the manufacturer’s ratings and derating guidance alongside the cabinet’s power distribution design.
02Are all LED display power supplies 5V?
No. The models listed here are 5V options, but the correct voltage comes from the specific module or equipment specification. Do not choose a replacement on current rating or physical appearance alone.
03How many PSUs does a cabinet need?
The quantity depends on module power demand, cabinet arrangement, PSU ratings, operating conditions and distribution design. Supply the equipment specifications for a project-specific recommendation rather than assuming a fixed PSU count per cabinet.
04Can unstable power cause flicker or brightness differences?
Power problems can contribute, but cabling, configuration, receiving cards and modules can also produce similar symptoms. Have a technician diagnose the system before replacing components.
05Can these supplies be exposed outdoors?
Do not assume so. Outdoor LED installations need an appropriate protective enclosure, ventilation and electrical design. Confirm the exact PSU’s environmental rating and installation requirements before use.
06Do you provide replacement and installation support?
Share the existing PSU label, cabinet details, quantity and site conditions. Sasha Corporation can help define a suitable supply and support scope. Electrical installation and testing should be completed by qualified personnel.
