MAX
Lightning Surge Protectors for
Electronics Equipment M-RESTER
LIGHTNING SURGE PROTECTOR
FOR POWER SUPPLY USE
(5 A; high discharge current capacity)
Functions & Features
• Designed specifically for AC power supplies up to 5 A
• Discharge current capacity 10000 A
• Absorbing surges only without affecting instrumentation signal
• No power supply interruption even when the surge absorber is broken
• Relay contact turns ON with surge absorber failure
• Surge absorber element replaceable without power interruption
Typical Applications
• High discharge current capacity is beneficial for use in area with frequent lightnings
