HBC Doppelbatteriemonitor, 12/24 V als Aufbauversion oder Einbauversion The dual battery monitor is ideal for the continuous monitoring of 2 separate batteries (starter and consumer battery). Available for 12 V dual-battery systems or 24 V dual-battery systems as a surface-mounted version for off-road vehicles or motorhomes. Nakatanenga has the exclusive distribution rights for the dual battery monitor in Europe. The digital technology used in these monitors makes it possible to accurately reproduce the non-linear characteristics of lead-acid batteries. Using the green button in the centre, you can switch the information output on the display from one battery to the next. The dual battery monitor emits an audible alarm/tone as soon as the battery is either overcharged (14.8 V and above) or over-discharged (12.2 V and below).  The dual battery monitor has been specially developed to be combined with the Cyrix-ct intelligent automatic cut-off relay. Link function: If you press and hold the green button on the dual battery monitor for 10 seconds, both batteries are forcibly connected in parallel for a few minutes, which is particularly useful when operating a winch or when the starter battery is too weak (only possible in combination with the Cyrix-ct cut-off relay). Features:  Warning in case of overcharging or excessive discharge  reverse polarity protection   Audible alarm (can be muted)  Energy-saving functions (automatic dimming of the screen depending on the ambient light, automatic sleep function = auto-sleep 10-30 minutes after the battery stops running) screws and a template with the distances of the necessary drill holes are included with the built-in version 3 m long cable  Operating elements summarised:Single button press (green button) = Change information output (from battery 1 to battery 2)  = Mute active alarm.Press and hold button for 3 seconds = Switch alarm off/on permanentlyPress and hold button for 10 seconds = Link function: Switch batteries in parallel for 30 seconds via the separately available cut-off relay (jump start) -> Only possible in combination with the Cyrix-ct cut-off relay Alarm function: - Level 1 = as soon as 14.8 V (29.6 V) is exceeded or 12.2 V (24.4 V) is fallen below: beeps every 10 seconds, screen lights up - Level 2 = as soon as 15.0 V (30.0 V) is exceeded or 12.0 V (24.0 V) falls below: beeps every 1/2 second, screen lights up -> as soon as the alarm goes off, you can mute it by lightly pressing the green button Specifications:  Dimensions: 69.5 x 50.5 x 20 mm (surface-mounted version) ; 85.5 x 66.5 x 20 mm (built-in version) Weight: 130 g incl. cable  Low-voltage warning: DC voltage below 12.2 V (24.4 V) Over-charge warning: DC voltage above 14.8 V (29.6 V)
