MODEL: MAA MAA SPECIFICATIONS ES-8168 Rev.6 Page 1/3 https://www.m-system.co.jp/ Lightning Surge Protectors for Electronics Equipment M-RESTER LIGHTNING SURGE PROTECTOR FOR POWER SUPPLY USE (5 A; high discharge current capacity; life monitor) Functions & Features

  • Designed specifically for AC power supplies up to 5 amps
  • Discharge current capacity 10000 A
  • Life monitor function helps you to decide when you should replace the M-RESTER; reduces maintenance and prevents downtime
  • LED display and alarm contact output indicate the degradation and life span of the surge protection circuits
  • No power supply interruption even when the unit is degraded or at the end of its life [1.97] 123 [4.84] [3.15] mm [inch] MODEL: MAA–[1]

ORDERING INFORMATION

  • Code number: MAA–[1] Specify a code from below for [1]. (e.g. MAA-100) [1] OPERATIONAL VOLTAGE 100: 100 V / 110 V / 120 V AC 200: 200 V / 220 V / 240 V AC GENERAL SPECIFICATIONS Construction: Plug-in Connection: M3.5 screw terminals (torque 0.8 N·m) Screw terminal: Chromated steel Housing material: Flame-resistant resin (black) Alarm indicators POWER: The green LED turns on while the circuit is alive and the internal fuse is not blown; and is off when the power supply is removed or the fuse is blown. ALARM: Tricolor LED (green/amber/red)
  • Remains off when the power supply is first turned on.
  • Green: The unit has received one or more surges.
  • Amber: Replacement is recommended.
  • Red: The life span has ended. Alarm output: The N.C. contact is on when the life span of the discharge elements has ended, when the voltage limiter has degraded, and/or when the power supply is removed. Rating: 125 V AC @ 0.5 A (cos ø = 1)
