Connection of BMS123 with AMETEK Latching relay

This diagram shows the connection ofthe AMETEK Latching Relay with BMS123.

The relay is controlled bythe BMS123 Load Relay NC contact. The auxiliary relay is powered by the DC main voltage and it will create the impulse signal for the latching relay to disconnect.

Since the main

The Basic Protection of the Battery Cells

1) Battery monitoring

The CPM1 serves as the battery monitoring device.

2) Flexible connection to each cell in the battery

The cells can be disconnected completely and easily. In this example the disconnection is done by means of the Battery link cable

GWL/Modular - ELERIX Holder = Flexi Rack Pack + BMS Basic

A simple solution for quick and easy assembly of the battery packs. The 8 cells can be assembled into a 6V (4P2S), 12V (2P4S) or 24V (8S) configuration.

The GWL/Modular solution is equipped with the BMS Basic for protection and management of the installation.
