Unmanaged ethernet switch ECU-08LMT

Unmanaged ethernet switch ECU-08LM.xT-05

ECU 08LM.7T – switch with PoE 7x at.

ECU 08LM.7T – switch with PoE 7x at.

A small ethernet busbar unit with 8 ports – economical version with extra 7x PoE output using negotiation as per the IEEE 802.3 at standard. These PoE outputs are primarily designed to power cameras in vehicles with output power supply -48V where the camera stream is stored on an external device in the vehicle - EPIS 4.0xEPIS 5.0x  or on a tachograph or elsewhere. The -48V voltage was chosen to ensure save connection of other devices – e.g. notebooks.

This ECU switch has mechanical measurements given by using M12 connectors. Its basic technical parameters are:
