1.1.6 Shoot First, Ask Questions Later

When the MicroPAC is operating in categories 1 to 3 and detects an increase in load current

applied to the output which incurs into the next power band the internal microcontroller will

turn all outputs on, regardless of the actual amount of load added. (Shoot ﬁrst ask question

later) with all the outputs enabled, the microcontroller will turn o redundant outputs

In the Power Shed Mode this is a constant cycle of detecting output load and continually

adjusting the outputs to satisfy that need.
