PMU-24 DL is a new and enhanced Power Management Unit featuring all the benefits of the PMU-16, now with 24 high-side outputs and internal data logging memory as a standard. All output states, voltage, and current information are transmitted via CAN bus to a dash display to inform the driver of potential problems. All logged data can be downloaded from the device for later analysis.

170 Amps total continuous current.
Operating voltage: 6-22V (immunity to transients according to ISO 7637)
Temperature range: AECQ-100 GRADE 1, -40 to +125°C.
10x 25 Amps high-side power outputs (all PWM capable).
6x 15 Amps high-side power outputs.
8x 7 Amps high-side power outputs.
Up to 16 analog inputs.
24x tricolor LED for each power output state.
2x CAN 2.0 A/B.
256 MB data logger memory.
Up to 500 Hz logging frequency.
Real-time clock for data stamping.
3D accelerometer/gyroscope.
Built-in “inertia switch” in case of an accident.

Decades ago, the critical electronic components in a race car were the ignition coil and points. Race cars are now sophisticated machines equipped with advanced engine management systems. Add to that dataloggers, radios, electric pumps, fans, dashboards and gauges and lights, and you end up with a lot of electrical equipment. All components need to be powered ON and turned OFF at the correct moments, and all components require circuit protection to prevent damage or fire in case of accident or component malfunction.

Historically these duties have all been managed using switches, fuses, and relays, but they have many shortcomings! First and foremost, each component must have its own switch, fuse, and relay, requiring wiring looms to run from the switch to each relay or component, adding complexity and weight. Fuses and relays are also susceptible to damage from vibration and high temperatures, both of which are commonplace in racing environments. Fuse failure is also difficult to diagnose during competition, and a driver is unlikely to be able to replace a fuse while racing. Partial solutions for this are automatic circuit breakers, but high ambient temperatures can cause breakers to trip well below their rating.

All of these problems can be solved by using intelligent power management units (PMUs). The newly developed ECUMaster range of PMU units are at the forefront of power management technology. Channels can be grouped for high-current devices. If more outputs are required than available on one device, multiple PMUs can be connected via CAN BUS. The PMU is a modern device that packages the functionality of fuses, relays and more in one sleek and small package.

All power outputs can be programmed using a vast array or parametric and logic sequencing enabling fault detection, reset and automated contingency strategies. For example secondary fuel pums deployment during fault or low fuel pressure detection. CAN-Bus communication links the unit to the ecu and touch button keypad for comprehensive switching and control operations. For example multiple wiper delay and speed options all controlled from one push button via sequence and push duration selections.
