Cyrix-ct 120A Battery Combiner – Voltage Sensitive Relay – CYR010120011

The Cyrix-ct 120A battery combiner is a voltage sensitive relay which combines your leisure battery and starter battery when a pre-set voltage is reached (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). This 120A model can charge a leisure battery at a rate of up to 120A/hr.

PLEASE NOTE: The Cyrix-ct battery combiner is a voltage sensitive relay that cannot be used with vehicles that have Euro 5 or Euro 6 engines, as they use a smart alternator. Most vehicles registered after September 2013 will be Euro 5 or Euro 6, and you can also check this on your V5C. If you have such a vehicle, you should instead use a battery to battery charger.

Use cases

It is only possible to use a voltage sensitive relay (VSR) in a vehicle which doesn’t have a Euro 5 or Euro 6 engine. Further to this, you can only use a VSR if you have lead acid (i.e. not lithium) leisure batteries.

Intelligent battery monitoring

Some voltage sensitive relays will disconnect a battery in case of a short but high amperage load. A battery combiner also may fail to connect a large but discharged battery bank because the DC voltage immediately drops below the disengage value once the batteries are connected. The software of the Cyrix-ct 120A does more than simply connect and disconnect based on battery voltage and with a fixed time delay. The Cyrix-ct 120A looks at the general trend (voltage increasing or decreasing) and reverses a previous

action only if the trend has reversed during a certain period of time. The time delay depends on the voltage deviation from the trend.

Protection against overheating

The Cyrix will disengage in case of excessive contact temperature, and reengage again after it has cooled down.
