PROTECTION FUNCTIONS
| 1. Over Temperature Protection | Automatically stops charging when internal temperature reaches 105°C / 221°F; LED flashes red alarm. |
| 2. Output Short-Circuit Protection | Cuts off output current upon short-circuit; LED flashes red alarm. |
| 3. Reverse Polarity Connection Protection | Disconnects charger when connected in reverse polarity; LED flashes red alarm. |
| 4. Output Over-Voltage Protection | Cuts off output current when output exceeds 35V. |
| 5. Output Current Limiting Protection | Triggers automatically when output current exceeds 48A. |
| 6. Cell Short Circuit Timer | Automatically enters next charging stage when safe time value is exceeded. |
CHARGING STAGES
| Stage | Condition | Description |
| T1 Pre-charge |
Voltage < 20.8V | Charges at 10A to activate and repair deeply discharged batteries; switches to T2 when voltage reaches normal value or timeout (10 min). |
| T2 Constant Current |
Voltage ≥ 20.8V Current ≥ 30A |
Charges at rated 40A current; switches to T3 when voltage rises above rated voltage or timeout (10 hours). |
| T3 Constant Voltage |
Current < 30A | Charging current gradually decreases; completes when voltage reaches highest value or timeout (5 hours). |
