Victron Cyrix-Li-Load 24/48V-120A Intelligent Load Relay

SKU: CYR020120450

The Cyrix Battery Combiner is a microprocessor-controlled heavy duty relay that automatically connects batteries in parallel when one of them has reached a pre-set voltage (indicating that the battery is being charged), and disconnects when the voltage decreases below float level (indicating that one or more batteries are being discharged). Cyrix Battery Combiners are an excellent replacement for diode isolators.

The 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.

The Cyrix-Li-load will disengage when its control input becomes free-floating. If the battery voltage recovers after disconnecting (which will happen when no other loads are connected to the battery), the output of the BMS will become high and the Cyrix will reengage after 30 seconds. After 3 attempts to reengage, the Cyrix will remain disengaged until the battery voltage has increased to more than 13V (resp. 26V or 52V) during at least 30 seconds (which is a sign that the battery is being recharged). Alternatively, a BatteryProtect can be used (advantage: very low power consumption).
