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

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.
