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.
