Get the benefits of short circuit management and auto reversing without adding
more boosters!

PM42 Quad Power Manager lets you use a single booster and divide its output into
4 power sub-districts for automatic reversing or to improve operation by

If you want to improve operation but don't need the added power (or expense) of
adding a booster, the PM42 is the right answer for you.

regular sub-districts and auto reversing sub-districts.
