(Operational voltage range 24 V ±10 %, ripple 10 %p-p max.)

P: 110 V DC

Lightning Surge Protectors for

Electronics Equipment M-RESTER

(Operational voltage range 85 – 150 V, ripple 10 %p-p max.)

LIGHTNING SURGE PROTECTOR FOR

GENERAL SPECIFICATIONS

Construction: Plug-in

STANDARD SIGNAL LINE & PULSE USE

(life monitor, 24 V, 48 V or 65 V DC line voltage,

photovoltaic system, instrument shelter)

Functions & Features

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

Housing material: Flame-resistant resin (black)

Alarm indicators

• Designed specifically for 4 – 20 mA DC and pulse signal

lines

PWR: The green LED turns on while the power is supplied.

ALM: Tricolor LED (green/amber/red)

• Absorbs surges only without affecting instrumentation

signal

· 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 surge protector; reduces time and effort for

maintenance and prevents downtime

Degradation judged: When the leakage current at the

voltage limiter exceed approx. 7.5 μA.

• LED display and alarm output indicate the degradation

and life span of the surge protection circuits

• Wide range of operating temperature from -20 to +70°C

(-4 to +158°F)

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.

STANDARDS & APPROVALS

EU conformity:

EMC Directive

EMI EN 61000-6-4

EMS EN 61000-6-2

Low Voltage Directive

EN 61010-1

Measurement Category II (alarm output)

Installation Category II (power)

Pollution degree 2

CAUTION

Before replacing the unit, make sure to turn off the power

supply for safety. Other factors such like an alarm system

connected to the line should also be considered.

The life monitoring circuit remains alive by the internal

backup circuit even when the external power supply is

removed. The LED is turned off in that case.
