The SSM series of active surge protectors are designed to handle high input surge voltage in accordance with RIA12. It can clamp up to 385V for 20ms to a safe value of 168V, suitable for 72, 96, and 110V railway systems.

The MCF series is designed for 28V systems of military-grounded vehicles and meets MIL-STD 1275D surge susceptibility and MIL-STD 461G EMC requirements. Its active surge clamping function also complies with RIA12 surge susceptibility for railway applications. The MCF series combines surge protection and EMC filtering, reducing the need for additional components and saving space in the system. It provides complete equipment protection.
