WTH-CS/AC
www.watchfuleyesolutions.com Smart Surge Protective Device

Description
Smart surge protector WTH-CS/… AC series are perfect suit for your power supply system as well as Data and Control System. The smart monitoring system came with multiple connection choice: RS485 - Cloud, Modbus. Easily extend cloud service capability, allows real-time remote monitoring and managing your surge protection system through cloud service.
WTH-CS/… AC serie splits currents to protect surge protector against potential damage from overvoltage. Widely used in data center or front-end equipment to protect power supply and cable from surge.
In accordance with: IEC 61643-1 - Class I and UL1449 Type 4 Location
