Lightning Surge Protectors
INDUSTRIAL PRODUCT LIST▼
• Life monitor function helps you to decide when you should replace the lightning surge protector; reduces maintenance and prevents downtime
• LED display and alarm contact output indicate the degradation and life span of the surge protection circuits
Without question, the main complaint in the industry with
regard to lightning surge protectors is the difficulty in determining
whether the surge or lightning protector installed to protect your control
system components is still functional. M-System's latest addition to their
vast variety of surge suppression devices solves this problem.
Lightning surge protector Models MDM2A and MAA provide 'health indication'
for easy monitoring, maintaining and verifying the functionality of these
control system protection devices. These lightning surge protectors include
an amber alarm indicator to alert panel inspectors that lightning surge
protector has reached its useful life and should be replaced before loss of
surge protection. If these units are not replaced promptly, the alarm
indicator changes from amber to red upon a complete loss of surge and
lightning protection.
In addition to the life monitor function, this counter function will help
you to gather statistical information on vulnerable spots throughout your
installation, for more efficient surge protection measures.
Modern day industrial equipment relies heavily on microprocessor-based
technology. This makes it essential for critical control components to be
protected from lightning, transients and surges. M-System lightning surge
protectors with health indication operate by monitoring the leakage current
from signal to earth ground. Additionally the number of suppressed surges is
also monitored. When a predetermined level of either the leakage current or
number of suppressed surges is exceeded, the health indicator illuminates.
Low in cost, these devices pay for themselves by providing early warning
alarms and reducing ongoing unnecessary panel maintenance. To give you an
idea of their functionality, consider opening a panel with a large number of
lightning surge protectors. Instead of unplugging and testing every unit,
for M-System's life monitor series all that is necessary is a quick visual
indication. No further tools or checking are required!
When it comes to comparing the cost of downtime versus lightning surge protector replacement, the choice is obvious.
