T2 DC500V Surge Protector Device SPD

The T2 DC500V Surge Protector Device SPD, manufactured in China, is a Type 2 surge protector positioned as a secondary protection device for low-voltage DC systems. After the primary protector has discharged strong surges, our product can continuously handle frequent small surges in the system, further controlling the voltage within a safe range, forming a complete protection layer.

Designed around the characteristics of DC500V circuits, this product balances industrial environment adaptability with long-term operational stability. It meets the protection needs of new energy scenarios and is also compatible with the safety standards of conventional DC power distribution systems. It is a mature product from GreenWatt in the field of DC electrical protection.

Technical Data

Product Details and Advantages

1.Protection Principle and Positioning

The GreenWatt T2 DC500V Surge Protector Device SPD, as a secondary protection device, primarily handles residual surges after primary protection. It suppresses frequent small overvoltages caused by nearby lightning strikes, equipment start-ups and shutdowns, and power grid fluctuations. Through rapid response and precise voltage limiting, it reduces the risk of equipment insulation aging and component breakdown, thus perfecting the system's protection chain.

2.Core Product Advantages

Precisely Adaptable to DC500V Systems

Our T2 DC500V Surge Protector Device SPD is customized for 500V DC operating conditions, ensuring high voltage matching and eliminating under-protection or over-protection issues. They are compatible with the voltage levels of mainstream DC systems such as photovoltaic and energy storage systems.

3.Stable Surge Discharge Capability

With a nominal discharge current of 20KA and a maximum discharge current of 40KA, it can stably handle daily surge impacts, with residual voltage ≤3.5KV, providing reliable protection for sensitive downstream equipment.

4.Wide Temperature Range Adaptability

Operating temperature range -40℃ to +70℃, humidity adaptability 5%–95%, enabling long-term stable operation in outdoor cabinets, industrial workshops, remote photovoltaic power stations, and other environments.

5.Intuitive Status Indication

Utilizes a red/green dual-color indicator; red represents normal operation, and green represents a fault condition. On-site maintenance personnel can quickly determine the equipment status, reducing maintenance difficulty.

6.Standardized and Quick Installation

Supports 35mm standard DIN rail mounting, requiring no additional cabinet modifications. Simple wiring significantly reduces on-site construction and replacement time.

7.Safe and Durable Structure

Utilizes flame-retardant materials and reliable internal components, featuring overheat and overcurrent protection logic, eliminating follow current risk, and enhancing overall operational safety.
