Ecumaster PMU16

Decades ago, the critical electronic components in a race car were the ignition coil and contact breakers. Now, race cars feature advanced engine management systems, anti-lock braking systems, paddle shifters, data loggers, radios, electric pumps, fans, and lights. All components must be controlled at the precise moment and require circuit protection to prevent damage or fire. Traditionally, fuses and relays fulfilled these functions but come with many disadvantages, such as complex wiring, susceptibility to vibration and temperature, and difficult diagnostics. Power Management Units (PMU). Our newly developed PMU unit is at the forefront of technology. It provides 16 high-current outputs (and allows for the use of multiple units if more outputs are required). One of the main advantages of the PMU is continuous current sensing and the auto-reset function if the current exceeds the defined level. All information about the status, voltage, and output current can be logged and transmitted via the CAN bus to dash displays to inform drivers about potential issues. An additional advantage of the PMU system is the ability to define logic for controlling the outputs. This is achieved with data from analog input channels or CAN bus data, and mathematical operations can be defined for each channel. The PMU is also equipped with LED indicators to show the status of each output. Thanks to the use of CAN bus keypads or steering wheel switches, wiring is significantly simplified and lightened. Two unique features are the built-in accelerometer and gyroscope for data logging and the inertia switch in case of a crash.

TECHNOLOGY

PMUs are 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 testing). 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 over a wide temperature range (AECQ-100 GRADE 1 (-40 to +125 °C)).
