DESCRIPTION
The CPE 80 and MB 80 provides protection of 32 data lines using up to eight (8) SPDs (surge
protection device). These products accomodate a variety of SPDs such as 232B, 422B and
420LB; which are not included with the motherboard or enclosure. Available from ProTek
Devices, each data line SPD has four, two stage protection circuits. The SPDs provide primary
and secondary protection against lightning, inductive switching and ESD transient threats. The
first stage diverts the transient current through the ground terminal return part and the second
stage clamps the voltage to a safe level without interruption of service.
These interface board assemblies are located between the unprotected transient threat environ-
ment (incoming data lines) and the protected sensitive electronic equipment or system. The
motherboard is marked identifying the protected side. The unprotected side should be located
away from the protected data line cables.
The MB 80 is a motherboard containing eight (8) edge card connectors and two (2) strip terminal
blocks. The edge card connectors are soldered onto the motherboard, which is connected to the
terminal blocks by copper traces. The terminal blocks have screw type connections for easy
installation between the unprotected and the protected equipment. Data line surge protection
devices are inserted into the edge card connectors for protection of sensitive equipment and/or
systems.
The CPE 80 includes a motherboard (MB 80) inside a rugged, cast aluminum housing with a
removable cover. The housing contains two (2) holes on either side of the case for data line
cables. Mounting hardware is provided for the data line cables.
