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 environment (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.
