3.0 PRODUCT DESCRIPTION
The Patton Model 515 DB-15 Surge Protector employs a solid
state hybrid network to guard DB-15 data ports against data loss and
hardware damage due to transient surges. Equipped with one male
and one female DB-15 connector, the Model 515 inserts between the
data cable and DB-15 port. The Model 515 intercepts data line
transients and sends them directly to chassis ground through the metal
D-shell.
Three versions of the Model 515 are available: The Model 515/25
clamps at 18 volts, protects all 15 pins, and is designed for use with
RS-232 interfaces. The Model 515/6 clamps at 7.5 volts, protects all
15 pins, and is designed for use with RS-422, RS-423 and RS-485
interfaces. The Model 515/T1 clamps at 7.5 volts, protects pins 1, 3, 9
and 11, and is designed for use with T1 equipment. All three versions
provide up to 1500 Watts of transient protection.
Warning: This product will not provide complete protection should your
equipment or building be subject to a direct lightening hit.
4.0 SURGE PROTECTION BENEFITS
The method of surge protection used in the Model 515 adds four
benefits to your system:
High Surge Capacity
The Model 515 handles up to 1500 Watts
of surge energy without failure.
Quick Response
The Model 515 has fast response times (1 pS
at the component level; 0.5 μS installed). Transient surges are
clamped at 18V for RS-232 and 7.5V for RS-422/423/485, and 7.5V for
T1 equipment.
Low Impedance
The Model 515 adds minimal load to your
system. It is about the same as a gender changer.
Open Failure
The Model 515 fails “open” if your system
experiences a severe transient or power fault above the rated voltage
of the protector. This means that data and surge energy is shunted
directly to chassis ground, rather than being allowed to flow throughout
the system.
