What is a Low-Voltage Surge Protector?

A low-voltage surge protector is a device engineered to shield electrical equipment in low-voltage power systems (typically ≤1000V AC/DC) from damage caused by transient overvoltages, also known as surges. These surges can stem from lightning strikes, power grid fluctuations, or the abrupt operation of heavy electrical appliances, posing a grave threat to sensitive devices such as computers, industrial controls, and renewable energy systems like solar PV installations.

Pole Options

• 1P SPD：Low-power DC devices (e.g., DC 500V/1000V PV modules), single-phase low-power appliances (AC 275V)
• 2P SPD：Medium-power DC circuits (e.g., DC 24V-1500V PV strings), single-phase medium-high power devices (AC 275V air conditioners)
• 3P SPD：3-phase medium-high power industrial equipment (e.g., DC 24V-1500V PV inverters)
• 4P SPD：3-phase high-power systems (e.g., AC 275V factory distribution rooms, commercial 3-phase power circuits)

Key Functions

• Transient Overvoltage Limitation: Instantly restricts unexpected voltage spikes to a range that won’t harm electronics.
• Surge Current Discharge: Efficiently diverts surge energy to the ground (via the “PE” terminal in the device), preventing it from reaching connected equipment.
• Device Longevity Extension: By blocking surges, it reduces wear and tear on sensitive components like circuit boards and power supplies.
• Multi-Scenario Application: Suitable for diverse setups, including solar PV systems, industrial control panels, and residential electrical networks.

Safety & Reliability

• Status Monitoring: Equipped with a green indicator light, it visually displays the operating status of the device, making it easy to detect faults in a timely manner.
• Robust Construction: Designed to withstand harsh electrical environments, ensuring consistent performance.
• Protection Scope: Shields against a wide range of surge events, from minor grid fluctuations to severe lightning-induced transients.
