The Cyrix Battery Combiner is a microprocessor-controlled heavy-duty relay that automatically parallels batteries when charging and isolates them again when voltages drop, providing near-zero voltage loss compared with diode isolators.

• Microprocessor-controlled relay for reliable automatic connect/disconnect
• Trend-based switching with adaptive time delays to prevent unwanted toggling
• Near-zero voltage loss - ideal replacement for diode isolators
• 12/24 V auto-ranging - detects system voltage automatically
• Long M8 bolts to allow connection of more than one power cable - 16 mm (0.63 in)
• Protection against overheating: disengages on excessive contact temperature and re-engages after cooling
• LED status indication (Cyrix 12/24 230 only): LED on = engaged; 10 s flash = disengaged; 2 s flash = connecting; 2 s blink = disconnecting; 0.25 s blink = alarm
• Prioritises the starter battery for alternator-driven charging

Alarm conditions indicated by the 0.25 s blink include over-temperature; voltage > 16 V; both batteries
