Electronically operated relay for simultaneous charging of two batteries (e.g. starting- and board-battery). The relay is installed between the two batteries, it stays disconnected until one of the batteries reaches a predetermined voltage level. Now the relay connects the two and both are fully charged. This method ensures that even when only using the vehicles for short distances the starter battery is always ready to go. Additionally, the Cyrix-ct software monitors the tendencies of the voltage levels and then optimizes the delay accordingly.   12/24 V Automatic: The Cyrix-ct relay automatically recognizes the voltage and adjusts the output. Heat protection: The Cyrix disconnects when he recognizes temperatures exceeding the optimal operating temperature and shuts of accordingly, the relay connects automatically once the temperature has fallen again.   Once you turn off your motor and the alternator no longer charges the batteries they are automatically disconnected to spare the starter battery for when you want to get going again. As soon as the voltage falls the relay allows for a short delay in the disconnect to keep the batteries from overloading. The Cyrix-ct operates based on past charging patterns and only deviates from these when changes to this pattern appear within a certain interval. The duration of the delay depends on the pattern of deviation in voltage.   Technical Details:  Operating voltage (automatically): 12 V / 24 V Peak Power: 300 A Consatnt Power: 120 A  Tightening voltage: from 13 V to 13,8 V and 26 V to 27,6 V with intelligent disconect Abfallspannung: Von 11 V bis 12,8 V und 22 bis 25,7 V with inteligent disconnect Power consumption when disconnected: <4 mA Power consumption when connected: 12 V: 220 mA ; 24 V: 120 mA Wire bolts: M6 Measuements: 46 x 46 x 80 mm Protection: IP54 Weight: 150 g   Connecting (V) DELAY   Disconnecting (V) DELAY V < 13 V Stays open   V < 11 V 0 s 13,0 V < V < 13,2 V 10 min   11,0 V < V < 12,0 V 1 s 13,2 V < V < 13,4 V 5 min   12,0 V < V < 12,2 V 10 s 13,4 V < V < 13,6 V 1 min   12,2 V < V < 12,4 V 30 s 13,6 V < V < 13,8 V 4 s   12,4 V < V < 12,8 V 3 min       >  12,8 V Stays connected       >  16 V Overload prevention

The four-pole relay for LED indicators prevents too fast blinking and allows to set its blink rate. It is replaced with the preinstalled relay of the Land Rover Defender 90/110/130.

For safety reasons, it is advisable to switch off the electric winch on the off-roader and only switch it on when needed. This is usually done with a disconnect switch in the engine compartment, so that awkward handling is necessary when you want to start the winch. With the switching relay and the switch supplied, this can be done conveniently from the driver's seat without having to lay the winch's power cables there. Only two thin wires are needed, the required switch is included in the delivery, the switching relay is mounted in the engine compartment. It has an additional switch directly on the relay housing and does not consume any power when it is not being switched. A recessed labelling field allows easy identification of the relay. The switch is a very high quality Carlingtech Contura switch (waterproof to IP67 standard), this fits seamlessly into our mounting frames or various consoles such as in the Land Rover Defender TD4 or other vehicles. The relay is designed for a continuous load of 500 A, please check if this is suitable for your winch. According to the manufacturer, a Warn 9.5XP requires 425 A, a Tabor 12K 457 A and the Warn 8274-50 450 A.
