MAA
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
MODEL: MAA–[1]

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.
