ECU Master PMU power distribution

Description Decades ago, the critical electronic components in a race car were the ignition coil and points. Race cars now feature advanced engine management systems, antilock brake systems, paddle shifters, dataloggers, radios, electric pumps, fans, and lights. All components need to be controlled at the correct moment, and all components require circuit protection to prevent damage or fire. 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 function if the current exceeds a defined level. All output state, voltage and current information can be logged and transmitted via a 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 analog input channels or CAN bus data, and math operations can be defined for each channel. The PMU is also equipped with LED indicators to show the status of each output. With use of CAN bus keypads or steering wheel switches, all wiring is vastly simplified and lightened. Two unique features are the inbuilt accelerometer and gyro for logging and ?inertia switch? in case of accident. TECHNOLOGY The PMU is assembled according to IPC-S-815A standards to ensure product reliability. The device is manufactured on an automated assembly line with optical inspection, and automated testing (including burn-in). The PCB material and design, special surface coating and IP65 enclosure ensure reliability even in the harshest environments. Carefully selected components allow for continuous and reliable operation across a very wide temperature range (AECQ-100 GRADE 1 (-40 to 125?C).

This ethos was also noticed by high caliber 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 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 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.
