Raycap Safetek products are high-performance surge protective devices (SPDs) specifically designed for DC and AC power applications. When used in environments such as Energy Storage Systems (ESS), they offer the following features and benefits.

 

Raycap Safetek Key Features

• High surge discharge current : Discharge capacity of up to 50-65kA (8/20). Reliably responds to large-scale surges.

• High TOV (Temporary Overvoltage) resistance : Resistant to temporary overvoltage.

• Maximum operating voltage : Various models available supporting up to DC 1,000V, AC up to 880V.

• Advanced thermal disconnector and thermal control technology : High safety and reliability.

• Vibration and shock resistance : Resistant to vibration and external shock in industrial environments and ESS devices.

• Pluggable design : Easy module replacement in the field.

• Remote Contact (RC) option : Supports remote monitoring of status signals.

• Maintain equipment power at end-of-life (EOL) : Keep devices powered without load loss even when replacement cycles are reached.

• International certifications : Obtained numerous international safety certifications, including VDE-IEC Class II/EN Type 2, UL Type 1CA, and Type 4CA.

 

Advantages of ESS application

• Protection of core equipment (PCS, batteries, etc.) of ESS systems : Protects internal equipment from lightning, grid overvoltage, and other surges to extend system life and ensure stability.

• Reduced maintenance costs : Excellent durability and long life (typically 5-10 years warranty, expected lifespan 10-20 years), easy module replacement to minimize offline time.

• Improved safety and reliability : High durability and high capacity characteristics provide the effect of preventing safety accidents (fire, explosion, etc.) in ESS.

• High-performance consistency : Patented technology that maintains protection performance without degradation even after thousands of repeated surges.

• Modular type : It can be customized to suit various operating voltages and environments, and can be widely used in large-scale ESS, microgrids, and renewable energy linkage systems.

 

summation

Raycap Safetek is a highly reliable surge protection solution optimized for ESS , offering clear advantages in system protection, reduced maintenance costs, and prevention of various accidents.

• Key features : high capacity, high durability, easy maintenance, international certification, modular structure

• When using ESS : protection of major equipment, improvement of system reliability and safety, cost reduction, long lifespan

 

Introducing Raycap Safetek to protect against momentary TOV increases that may occur due to battery charging/discharging in ESS is a very effective choice for stable operation and long-term protection of the entire energy storage system.
