⚡ Quick Start Guide & Important Tips

🔹 What It Does & What You Need
✅ This module does:

Priority to DC input; auto switch to battery on failure

5-48V, 10A load

Protects battery from over‑discharge (with external protection)
❌ This module does NOT: Charge battery (need separate charger), provide instant seamless switching (brief power loss)
🔧 You will need: Main DC supply (5-48V), backup battery (same voltage), load device
📦 Package includes: YX850 module × (as per SKU)

🔹 Wiring & Usage

⚠️ Important:

Voltage match: Battery voltage must equal main power voltage.

Switch time: Brief power loss (ms to seconds) – may reset sensitive devices. Test first.

Battery charging: Not included – use external charger.

Current limit: ≤10A continuous.

Polarity: Do not reverse.

Heat: Ensure ventilation at high load.

Application Examples

🔹 Common Questions

❓ Will my device restart?
Depends on device tolerance. Routers and cameras usually survive. Test before critical use.

❓ Does it charge the battery?
No. Use a separate charger.

❓ Can I use 5V?
Yes – main and battery both 5V.

❓ 10A continuous?
Yes, 10A continuous. Higher peaks possible but not recommended.

❓ Battery voltage lower than main?
No – must be same voltage.
