Protection from
Power Surges - Point 5 of Six Point Plan
Electrical
and electronic circuitry in computing, communications and control /
alarm installations are highly susceptible to damage from lightning,
surges and other transient pulses.
These
impulses may arrive via power, telecommunications or signal
line following direct lightning strikes or following
inductive, capacitive or conductive coupling.
HOW DO WE PROTECTED YOU FROM POWER SURGE ?
-
High
let-though voltage
-
Wavefront
unaltered
-
Energy
diversion only
-
Independent of
load current
-
Point-of-entry, coarse prot'n
|
-
Low let-though
voltage
-
Wavefront
slowed
-
Energy
diverted and filtered
-
Sized based on
load current
-
Essential for
electronic, comms - fine protection
