MDA-TL

Lightning Surge Protectors for
Electronics Equipment M-RESTER

LIGHTNING SURGE PROTECTOR FOR
ANALOG TELECOM LINE USE

(life monitor)
Functions & Features
•Designed specifically to protect telecommunication equipment from lightning surges entering through telecommunication line network
•Absorbing surges only without affecting instrumentation signal
•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

MODEL: MDA–TL–[1]

Alarm indicators
  Power: The green LED turns on while the power is supplied.
  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.
  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 and/or when the power supply is removed.
