a) Short-circuit across a 6A output of a PISA11.203206 protection module

Parameters:

Power supply: 5A (CS5.241)

I0 = 0A

I3 = Short-circuit

I1, I2, I4 = 0A

8A is flowing, which is the current level that can be drawn from the CS5.241

power supply without the supply voltage falling below 21V. The electronic

circuit in the PISA protection module can actively limit this current for

340ms. After this time period, the outputs shutdown in order to protect the

MOSFET in the PISA module.

Refer also to Fig. 6-2 of this datasheet.

b) Short-circuit across a 3A output of a PISA11.203206 protection module

Parameters:

Power supply: 5A (CS5.241)

I0 = 0A

I1 = Short circuit

I2, I3, I4 = 0A

Similar situation as above (short circuit across the 6A output).

The same 8A is flowing, which is the current level that can be drawn from

the CS5.241 power supply without the supply voltage falling below 21V.

The electronic circuit in the PISA protection module can actively limit this

current for 340ms. After this time period, the outputs shutdown in order to

protect the MOSFET in the PISA module.
