Trusted Power System 4. Power Pack Specifications
Rockwell Automation Publication PD-T823X Issue 11 15
The graph shows the response of a single Power Module to severe overloads. As the load is
increased the power supply protection mechanism operates and shuts down the output. It
can be seen that for a period of just in excess of 200 ms the Power Module can provide
currents up to 115 A or 380 % of its stated maximum(115/31 = 3.8). This 200 ms/380 % can
be extrapolated for additional power supplies in order to perform MCB discrimination
studies.
