Overvoltage Protection

Stops/reduces output if input/output voltage exceeds safe range; prevents grid voltage spikes (e.g., lightning-induced high voltage) from damaging LED beads.

Shields against voltage surges, preventing premature aging/damage from overvoltage.

Short circuit Protection

Detects output short circuits (via sudden current changes) and quickly cuts off output or enters low-power mode.

Blocks high short-circuit currents from burning internal components (e.g., thyristors, MOSFETs), preventing greater losses.

Over temperature protection

Internal temperature sensor detects overheating (from overload, high ambient temp, or poor heat dissipation) and triggers power reduction/shutdown.

Prevents overheating-induced component degradation, shortened lifespan, or damage; avoids fire risks.

Overload Protection

Limits/closes output if load exceeds rated power, avoiding overheating damage from long-term overload.

Limits current/power to protect driver and LED beads from overcurrent damage; reduces overheating/short-circuit risks, extending system lifespan.

Open circuit Protection

Detects output disconnection (via voltage spike/current drop) and shuts down/limits voltage to prevent overvoltage damage.

Protects internal components from overvoltage damage; reduces high-voltage risks, extending equipment lifespan.

Lightning Protection

Surge protector clamps lightning-induced high-voltage surges to safe levels, diverting current to ground to protect driver and LED arrays.

Effective in outdoor settings (e.g., streetlights, billboards) to prevent lightning damage, enhancing system reliability under harsh weather.
