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.
