LIGHTNING SURGE PROTECTOR
FOR POWER SUPPLY USE
(10 A; high speed/high discharge current capacity)
Functions & Features
• Designed specifically for AC power supplies up to 10 A
• Discharge current capacity 20000 A
• Absorbing surges only without affecting instrumentation signal
• Indicator LED turns off with surge absorber anomaly
• Fuse provided for preventing ignition caused by failure of surge absorber
Typical Applications
• High discharge current capacity is beneficial for use in area with frequent lightnings
