MODEL: MDW2A-4R

Lightning Surge Protectors for

Electronics Equipment M-RESTER

GENERAL SPECIFICATIONS

Construction: Plug-in

Connection: M3 screw terminals (torque 0.8 N·m)

Screw terminal: Chromated steel

LIGHTNING SURGE PROTECTOR FOR

Housing material: Flame-resistant resin (black)

Alarm indicators

RS-485 / RS-422

(life monitor)

PWR: The green LED turns on while the power is

supplied.

Functions & Features

•Designed specifically for RS-485 or RS-422 transmission

line

ALM: 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.

•Life monitor function helps you to decide when you should

replace the M-RESTER; reduces maintenance and prevents

downtime

•LED indicator and alarm contact output indicate the

degradation and life span of the surge protection circuits

Degradation judged: When the leakage current at the

voltage limiter exceed approx. 0.25 mA.

Life time judged: When the number of discharges of the

discharge element reaches the expected life span.

Alarm contact: The N.C. contact is on when the life span of

the discharge elements has ended, when the voltage limiter

has degraded or when the power supply is removed.
