ePDM 70-150

Electronic power distribution for the vehicle electrics

The ePDM 70-150 is an electronic power distribution controller that can control a variety of loads. It has a large number of outputs up to 35 A. The controller is designed to meet the requirements of a modern vehicle and, in addition to powering the loads, allows also the integration of numerous diagnostic functions. With ePDM 70-150, different wake-up scenarios can be implemented. The „Always-ON“ outputs provide power to modules, such as a telematics module, even when the ePDM is switched off.

The controller communicates via CAN bus and is fully programmable. The WEcontrol Designer provides a powerful programming environment. For system protection, e.g. against open load or overcurrent, you can implement diagnostic functions and configure the outputs using “fuse-like” function blocks.
