MAAC

Lightning Surge Protectors for
Electronics Equipment M-RESTER

LIGHTNING SURGE PROTECTOR
FOR POWER SUPPLY USE
(5A; high discharge current capacity; life monitor/surge counter)

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

MODEL: MAAC–[1]

ORDERING INFORMATION
• Code number: MAAC–[1]
Specify a code from below for [1].
  (e.g. MAAC-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)
Indicators
  Surge counter
: 7-segment, 3-digit, red LED; The LED flashes when the life span of the discharge element is near to the end, recommending replacement of the M-RESTER; turns off when the life is ended.
  PWR: 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: The LED turns on when the life span of the discharge element has ended and/or the voltage limiter has been degraded.
  Degradation judged: When the leakage current at the voltage limiter exceed approx. 3mA; or when the fuse is blown.
  Life time judged: When the number of discharges of the discharge element reaches the expected life span.
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.
