CPCI Loadboard 3 U

The CPCI load test card serves to simulate loads on CPCI systems. Both electrical and thermal conditions can be simulated.

The following load streams can be switched with the coding and tilt lever switches located on the front plate:


 load current Control options
5 V
 0 A ... 8.25 A
 in 0.55 A stages
3.3 V
 0 A ... 10.5 A
 in 0.7 A stages
+12 V
off/1 A
-12 V
off/1 A

 

5 V must always be connected as control voltage.

Voltages are tapped at the CPCI bus via the P1 plug.

Excess temperature protection

The load test card switches itself off at a temperature on the topside of the load test card or in the rack of 120 °C +-5 K. Once cooled, it turns itself on again.

Please note:

The load test card becomes hot during operation.

The incoming voltage levels for the voltages 5 V, +12 V, 3.3 V and -12 V can be measured at measuring points close to the plug P1. These measuring points are run via the plug X1 (on the front plate).

Furthermore, 4 PTC resistors (PT100) are attached to the load test card: On the front at bottom and top and on the back at the bottom and top. It is possible to measure the temperature on the load test card or in the rack via these. These PTC resistor connections are also run via the plug X1.
