Selection & Safety Notes

Wrong PSU selection may cause flicker, overheating, voltage drop, and long-term damage.

For high-current PSU, design DC distribution correctly to reduce heat and voltage drop.
For outdoor cabinets, grounding and surge protection are strongly recommended.
Keeping spare PSU units helps reduce downtime.

Installation & Wiring Tips

Following safe installation practices reduces downtime and keeps cabinet wiring clean.

Install PSU in an airflow-friendly location.
Run high-load (full-white) test during commissioning.
Use correct cable gauge; thin cable increases drop and heat.
