Victron Battery Isolators Combiners in 120 to 400A

 Cyrix Microprocessor Controlled

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.

 

Diode Battery Isolators allow simultaneous charging of two or more batteries from one alternator, without connecting the batteries together. Discharging the accessory battery for example will not result in also discharging the starter battery. Low voltage drop due to the use of high efficiency Schottky diodes.

 

Similarly to diode battery isolators, FET isolators allow simultaneous charging of two or more batteries from one alternator (or a single output battery charger), without connecting the batteries together. In contrast with diode battery isolators, FET isolators have virtually no voltage loss. Voltage drop is less than 0,02 Volt at low current and averages 0,1 Volt at higher currents.

 

Diode Battery Combiners are used to guarantee continuous DC power to mission critical equipment, such as an electronic engine control system. With a Diode Battery Combiner two or more DC power sources can be used in parallel to supply the mission critical load. Failure of one source will not interrupt power to the critical load.

 

Cyrix-Li-ct

The functionality of the Cyrix-Li-ct is analogous to the Cyrix-ct.

The Cyrix-Li-ct will parallel connect a lead acid starter battery and a LiFePO4 battery:

- if the Charge Disconnect output of the VE.Bus BMS is high, and

- if it senses 13,4V (resp. 26,8V) or more on one of its power terminals. The Cyrix will disengage immediately:

- when its control output becomes free floating, signalling cell over voltage or cell over temperature, and/or

- when battery voltage drops below 13,2V.

Start assist function: a short positive pulse will close the relay during 30 seconds.

A built-in transient voltage suppressor will limit the voltage spike that may occur when the Cyrix suddenly disengages due to cell overvoltage or over temperature.

 

The Cyrix-Li-load will disengage when its control input becomes free floating. If the battery voltage recovers after disconnection (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 battery voltage has increased to more than 13 V (resp 26 V or 52 V) during at least 30 seconds (which is a sign that the battery is being recharged).

 

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 13,7 V (resp. 27,4 V or 54,8 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).
