Traditionally, fuses and relays served all of those purposes, but they have many disadvantages like complicated wiring looms, sensitivity to vibration/temperature, and difficult diagnostics. All of these problems can be solved by using intelligent power management units (PMUs). Our newly developed PMU unit is at the forefront of technology. It provides 16 high current outputs (and use of multiple units if more outputs are required).  

One of the main advantages of the PMU is continuous current sensing and self-resetting functionality if current exceeds the defined level. All output state, voltage and current information can be logged and transmitted via CAN bus to dash displays to inform drivers of potential problems. An additional advantage of the PMU system is the ability to define logic for controlling outputs. This is done with data from analogue input channels or CAN bus data, and math operations can be defined for each channel.

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 utilizes a RadlokTM
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

Compared to the standard PMU16, 6 low side outputs have been added
and are rated at 1 amp 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 substantial savings
and saves the hassle of ordering separate components.
