ECU Master PMU-16-AS Autosport Version PMU Power Management Unit



Ecumaster as a brand quickly became popular for delivering excellent value for money products. This ethos was also noticed by high calibre motorsport customers and OEMs , that developed a need for a more professional line of products. For this reason, we would like to introduce our new PMU16 AS. The PMU16 Autosport Version is designed for demanding customers and installations where reliability and robustness is priority. Autosport connectors represent the highest quality connector available, and are the standard for professional motorsports and aerospace industries. The battery connection utilises a Radlok connector rated to 200 amps that can be disconnected without the need for any tools. The output connector is a custom 18 pin, 12 gauge connector designed and manufactured specifically for Ecumaster. The unit features an IP65 environmental protection rating, permitting its use in the harshest of conditions, including dusty and wet environments.
Compared to the standard PMU16, 6 low side outputs have been added and are rated at 2 amps per channel. 14 of the main output channels are rated at 25 amps, with two output channels rated at 40 amps.
As always with Ecumaster products mating connectors and terminals are included at no extra cost, which represents a substantial savings and saves the hassle of ordering separate components.
