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

PERFORMANCE

Discharge voltage (peak-to-peak)
  Line to line:
  ≥ 190 V (MAX-100)
  ≥ 410 V (MAX-200)
  Line to ground: ≥ 640 V
Maximum surge voltage
  Line to line:
  ≤ 350 V (MAX-100)
  ≤ 700 V (MAX-200)
  Line to ground: ≤ 800 V
(Withstand voltage of protected equipment between circuit and metal housing must be 1000 V AC or more.)
Note: This is the maximum voltage that could pass through M-RESTER. Protected equipment must be able to withstand this voltage for very short time period.
Response time: ≤ 0.01 μsec.
Leakage current
  Line to line:
  ≤ 1 mA at 150 V DC (MAX-100)
  ≤ 1 mA at 300 V DC (MAX-200)
  Line to ground: ≤ 1 mA at 300 V DC
Discharge current capacity: 10000 A (8/ 20 μsec.)
Maximum load current: 5 A
Internal series resistance: ≤ 0.5 Ω including return
