Selection & Safety Notes

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

Calculate PSU quantity and load based on cabinet and module count.
Use thick DC cable and proper distribution planning to reduce voltage drop.
For outdoor or unstable grid conditions, use surge protection and proper grounding.
Low-quality PSU may increase ripple/noise and cause flicker or module damage.

Installation & Wiring Tips

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

Use proper fuse/MCB on the AC input side.
Verify DC output polarity (V+ / V-) before powering on.
Cable labeling makes future maintenance easier.
Keep proper ventilation and airflow to reduce heat build-up.
