Victron Cyrix-Li-charge 24/48V-120A intelligent charge relay (CYR020120430)
Victron Cyrix-Li-charge 24/48V-120A intelligent charge relay 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 13,0 V (resp. 26,0 V or 52,0 V) or more on its battery charger connection terminal, and – if it senses 2 V 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 3 seconds When the Cyrix-Li-Charge is engaged (charger connected to battery) it will disengage after 1 hour to check if the charger is still enabled. If, after the Cyrix has disengaged, the output of the battery charger immediately increases to 13,0 V or more, the Cyrix will reengage, with a 3 seconds delay. Note: 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 13,5 V.
