CTEK Multi XT 14000 24V Battery Charger

The Ctek MULTI XT 14000 battery charger is a powerful charger for 24V battery banks: in boats, vehicles and workshops.

With built-in functions that constantly analyse the state of the battery - including temperature sensing - the CTEK MULTI XT 14000 battery charger ensures that batteries up to 300Ah (500Ah for maintenance) provide maximum performance at all times.

This charger can also be used as a power supply.

FEATURES & BENEFITS

• Eight step, fully automatic switch mode model.
• Revives, charges, checks and maintains virtually all types of 24V lead-acid batteries (Wet, MF, GEL and AGM) from 28Ah to 300Ah, up to 500Ah maintenance.
• Desulphation mode with pulses.
• Soft start for severely discharged batteries.
• Recondition mode with controlled top charging recovers the capacity of a severely discharged battery.
• Maintenance pulse charging increases battery life and gives superb performance.
• Supply mode for use as a power pack, battery backup (UPS) or float maintenance.
• Charges even drained batteries.
• Temperature compensated for optimal charging voltage at all times.
• Low back current drain, low ripple and input voltage independent (170-260V).
• High efficiency: 85%
• The charger can be connected for months, ideal for seasonal vehicles.
• Compact design with mounting holes for permanent assembly.
• 2 year warranty.

SAFETY FEATURES

• Electronic safe, the charger will not damage vehicle electronics. The battery does not normally need to be disconnected from the vehicle when charging.
• Minimal gas build-up and a patent-pending spark protection system. (however, in supply mode the spark free feature is disconnected).
• Short circuit and reverse polarity protected.
• Double insulation.
• Cooling with power controlled fan.
• Approved for outdoor use, (IP44).
• Progressive temperature protection.

*) Back current drain is what drains the battery if the charger is connected without the power cord connected.

**) Ripple denotes the amount of interference there is to the current and voltage. A high current ripple heats the battery and shortens its life. A linear charger has a current ripple of 70 - 400% which is much larger than the maximum 5% for a modern sealed battery. Voltage ripple could harm other equipment, which is connected to the battery.

MULTI XT 14000 delivers voltage and current with very low ripple. The battery gains a long service life and there is no risk of damage to other electronic devices connected to the battery.

***) IP 44 cannot be guaranteed unless the charger is positioned with its top or long side facing up.
