The RSS-300 should be specified to
protect electronic equipment that connects to an RS-232 line. The RSS-300
provides protection on up to three (3) individual RS-232 lines.
The RSS-300 is a very heavy duty
RS-232 line surge suppressor designed to protect sensitive
electronic equipment from damage caused by voltage transients
appearing on an RS-232 data line. Up to three (3) RS-232 signal
lines can be protected. For example, RXD, TXD and RTS.
Protection is provided from line-to-line and from line-to-ground.
What distinguishes the RSS-300 from other
suppressors is our unique three-stage design. Very high speed
bi-directional SIDACTORsTM work in combination with MOVs and
three-element heavy-duty gas discharge tubes to provide a suppressor
that has an extremely fast response time yet can also dissipate
large amounts of energy. Inter-stage wirewound resistors provide
better surge current handling than competing carbon-film designs.
Wide PC board traces and ground planes provide additional surge
