The SLP range is a series of surge protection devices combining
high packing densities, application versatility, proven hybrid circuitry
and simple installation – features which make the range the most
cost effective surge protection solution for process control equipment
systems and communications networks.
The multi-stage hybrid surge protection network at the heart of
the SLP uses a combination of solid state electronics and a gas filled
discharge tube (GDT) to provide surge protection up to 20kA. This
impressive surge protection circuit is designed to exhibit exceptionally
low line resistance and adds only a tiny voltage drop to the circuit.
In operation, the SLP device does not adversely affect the
performance or operation of the loop or combined equipment. The
device allows signals to pass with very little attenuation while diverting
surge currents safely to earth and clamping output voltages to safe
levels.
Fully automatic in operation, SLP devices react immediatley to make
sure that equipment is never exposed to damaging surges between
lines or the lines and earth. Reacting instantaneously, the SLP redirects
surges safely to earth and then resets automatically.
The versatile SLP range design considers the need for high packing
densities and has a product combining protection for two process loops
into one case. Each module provides full hybrid surge protection for two
process loops.
For higher bandwidth applications, the SLP range has been developed
to meet the demands of today’s highest speed communication systems.
One simple manual operation clamps modules securely onto DIN
rail, which automatically provides the essential high-integrity earth
connection.
A 10 Year ‘No Fuss’ warranty is available as standard for the SLP so if
a correctly connected device should fail for any reason, simply return it
for a free replacement.
‘Top-hat’ (T-section) DIN rail is generally suitable for mounting SLP
modules although for adverse environments, a specially-plated version
is available.
