Victron Energy Cyrix-Li-charge 12/24V 120A Intelligent Charge Relay

Description

The Cyrix-Li-Charge will connect a battery charger with 3 seconds delay:  if the Charge Disconnect output of the VE.Bus BMS is high, and if it senses 13,7V (resp. 27,4V or 54,8V) or more on its battery charger connection terminal, and if it senses 2V or more on its battery terminal (the Cyrix will remain open, if not connect to the battery).

The Cyrix-Li-Charge will disengage immediately whenever its control input becomes free floating, signalling cell over voltage or cell over temperature.

In general a cell over voltage alarm will reset shortly after charging has been stopped. The Cyrix will then reconnect the charger after a delay of 3 seconds. After two attempts to reengage with 3 seconds delay, the delay increases to 10 minutes.

Whenever battery voltage is less than 13,5V (resp. 27V or 54V), the Cyrix will disengage with a delay of 1 hour. Note 1: In case of zero discharge current, or a small discharge current, the Cyrix will not disengage shortly after the charger has been switched off and/or disconnected, because battery voltage will remain higher than 13,5V. Note 2: If, after the Cyrix has disengaged, the output of the battery charger immediately increases to 13,7V or more, the Cyrix will re-engage, with 3 seconds delay
