c) 6A Overload (4 Ohm resistive load) of the 3A output of a PISA11.203206 protection module

Parameters:

Power supply: 5A (CS5.241)

I0= 0A

I1 = 6A (4Ohm)

I2, I3, I4 = 0A

6A is flowing on output 1, which can be drawn from the CS5.241 power

supply with full output voltage. The electronic circuit in the PISA protection

module allows this current for 1s. After this time period, the outputs

shutdown in order to protect wires and loads.

Refer also to Fig. 6-1 of this datasheet.

d) Both 6A outputs of a PISA11.203206 module loaded with 6A (4 Ohm resistive load)

Parameters:

Power supply: 5A (CS5.241)

I0, I1, I2 = 0A

I3, I4 = 6A (4Ohm)

The power supply can not deliver the required current and switches into

current limiting mode. The PISA module only permits so much current on

the outputs so that the input voltage does not drop below 21V. With these

conditions, there is only 16V (8A * 2Ohms) on the outputs of the protection

module.

The electronic circuit in the PISA protection module actively limits this

current for 5s (fixed time setting) before the outputs shutdown. Please note

that the time can be shorter if the internal MOSFET needs to be protected.

e) The power supply is directly loaded with 4A (6 Ohm resistive load) and one 6A output of a PISA11.203206

module is loaded with 6A (4 Ohm resistive load)

Parameters:

Power supply: 5A (CS5.241)

I0 = 4A (6 Ohm)

I3 = 6A (4 Ohm)

I1, I2, I4 = 0A

The power supply can not deliver the required current and switches into

current limiting mode. The PISA module only permits so much current on

the outputs so that the input voltage does not drop below 21V. With these

conditions, there is only 18V on the outputs of the protection module.

The electronic circuit in the PISA protection module limits this current

actively and shutdown after 5s.
