Lightning Surge Protectors for
Electronics Equipment M-RESTER
Alarm indicators
PWR: The green LED turns on while the power is supplied.
ALM: Tricolor LED (green/amber/red)
LIGHTNING SURGE PROTECTOR FOR
· Remains off when the power supply is first turned on.
· Green: The unit has received one or more surges.
· Amber: Replacement is recommended.
STANDARD SIGNAL LINE & PULSE USE
(life monitor, 48 V or 65 V DC line voltage)
Functions & Features
· Red: The life span has ended.
Degradation judged: When the leakage current at the
voltage limiter exceed approx. 7.5 μA.
• Designed specifically for 4 – 20 mA DC and
pulse signal line including both 4-wire and 2-wire
transmitters
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.
Rating: 125 V AC @ 0.5 A (cos ø = 1)
• Absorbs surges only without affecting instrumentation
signal
• Life monitor function helps you to decide when you should
replace the surge protector; reduces maintenance and
prevents downtime
30 V DC @ 1 A (resistive load)
• LED display and alarm contact output indicate the
degradation and life span of the surge protection circuits
Maximum switching voltage: 125 V AC or 110 V DC
Maximum switching power: 62.5 VA or 30 W
Minimum load: 5 V DC @ 1 mA

CROSSOVER WIRE
A crossover wire between M-RESTER ground and ground or metallic
housing of equipment is required for protection.
If the protected equipment has no ground terminal, ground the
M-RESTER only.
