⚡ Key Special Features of DC SPD
1. Ultra-Fast Response Time
- Reacts within nanoseconds (<25 ns) when surge occurs
- Protects sensitive equipment instantly from lightning or switching spikes
2. High Energy Absorption Capacity
- Can handle very high surge current (kA level)
- Absorbs and dissipates large surge energy safely
3. Voltage Limiting (Clamping Protection)
- Limits overvoltage to a safe level (Up value)
- Prevents damage to inverter, battery, solar system etc.
4. Automatic Operation (Self-Acting)
- Normally stays in high resistance mode
- During surge → switches to low resistance path → diverts surge to ground
- Returns to normal after surge
