2.3.3 Auxiliary Output
The SP has a configurable auxiliary output (relay contact, nominal switching capacity is 2A up to
30VDC), of which can be used for default wake up, or remote switch devices such as alarm . Only
one function can be designed at a time. Please refer to chapter 5.5.
The auxiliary contact output was designed to energize a low current circuit.
Connecting to a high amperage device will possibly damage the equipment and it is
out of warranty.
2.3.4 TBB premium II charging algorithm
Adaptive charging
Fitted with multistage charging algorithm (bulk-absorption-float-recycle), the TBB premium II
charging algorithm is designed to charge battery quickly and fully. Microprocessor controlled
charging algorithm with variable absorption charging timer guarantee the optimal charging for
batteries of different discharged state.
Float charging and Recycle charging program guarantee your battery could get proper maintenance
in case of long time connected.

Note1: At this moment, the external load current of the battery is greater than the maximum
charging current of the charger, and the battery voltage starts to drop.
Note2: When the battery voltage is lower than 12.5V for 5 minutes, the charging state of the charger
changes from floating charging to constant current charging. At this moment, the external load
current of the battery is less than the maximum charging current of the charger, and the battery
voltage starts to rise.
Battery temperature compensation
Battery temperature is a key factor in correct charging, the charging formula must be adjusted
(automatically and in real time) according to the actual battery temperature to ensure that battery
are fully charged but not overcharged or undercharged. All charging voltages recommended by
