Ecumaster PMU-16

ECUMaster PMU-16 Power Management Unit

The ECUMaster PMU-16 is an intelligent power distribution module for performance and motorsport vehicles. It can replace conventional fuse and relay systems while providing programmable logic, current monitoring and CAN communication for pumps, fans, lights, wipers and other electrical equipment.

• 16 protected high-current outputs with individual current and voltage measurement
• Up to 150A total continuous output
• 16 configurable analogue inputs
• Two CAN 2.0B interfaces
• Programmable logic, timers and specialist vehicle functions
• Designed for reliable operation in demanding automotive environments

A compatible USB-to-CAN interface is required for programming. See the linked accessory below or browse the ECUMaster collection for keypads, wiring and CAN accessories. This standard PMU-16 does not include the internal logging memory fitted to the PMU-16 DL version.

Technical specifications

Please note, a USB to CAN cable or equivalent is required to program the PMU.

TECHNOLOGY

The PMU16 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 and special surface coating 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).
