Ρελέ Victron Energy Cyrix-Li-Load 24/48V-230A (CYR020230450)

The Cyrix-Li-Load 24/48V-230A battery combiner from Victron Energy (MPN CYR020230450) for 24V and 48V LiFePO4 batteries. It can operate with a maximum current of 230A and is, among other things, an ideal complement to the VE.Bus BMS as a battery switch for loads that the VE.Bus BMS cannot switch independently.

• Function of the Cyrix battery combiners in general

The Victron Cyrix-Li-Load 24/48V-230A is a high-performance microprocessor-controlled relay that automatically connects batteries in parallel when one of them has reached a predetermined voltage value (indicating that the battery is being charged) and disconnects the batteries again when the voltage drops below the float voltage value (indicating that one or both batteries are being discharged). Cyrix battery combiners are excellently suited to replace diode isolators. Their main feature is that there is virtually no voltage loss, so that the output voltage of alternators or battery chargers does not need to be increased.

• Operation of the Cyrix-Li-Load 24/48V 230A

The Cyrix-Li-Load 24/48V 230A switches off when its control input reaches the "free floating" state (open circuit).

If the battery voltage recovers after switching off (which happens when no other loads are connected to the battery), the BMS output goes high and the Cyrix switches on again after 30 seconds. After 3 switch-on attempts, the Cyrix remains off until the voltage has risen above 13 V (or 26 V or 52 V) for at least 30 seconds (which is an indication that the battery is being recharged).

• Important technical features
• Continuous current and cut-off current: 230A
• For 24V and 48V battery voltage
• Cyrix-Li-Load as a perfect complement to the VE.Bus BMS

A central core of the protective measures for Victron LiFePO4 batteries is the VE.Bus BMS. However, not all loads or chargers can be controlled directly via the VE.Bus BMS. To switch off such loads or chargers, several VE.Bus BMS controllable Cyrix switches are available.
