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

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.
