The TBB Power Trident BS1240 is a smart, compact battery charger that looks after your on-board batteries. It is designed to be highly efficient (up to 88%) and has two isolated outputs for independent charging of two battery banks, up to 40A total. A separate 3A slave charger output gives independent support to charge a starter battery.
Multi-functional smart buttons make it easy to program the charger for battery type, mode (charging or power supply) and a user definable output current, and it remembers the settings even after power down. Built-in voltage compensation and temperature compensation, via the included temperature sensor, give accurate and efficient charging whatever the battery chemistry, with 5 step charging profiles for AGM, GEL and wet lead acid batteries and a specific profile for Li-ION batteries. The AC input cable (1.4m) is supplied, so you only need to add the output cables; the M4 terminals accept cable sizes up to 16mm².
For caravans, motorhomes, marine use and ambulance/utility vehicles, for maintaining batteries during storage and for general battery charging, with 12V AGM, GEL, wet lead acid or Li-ION batteries. It runs from an input voltage of 165V AC to 265V AC.
