As optional, it’s availablea 48V version of DST2700, particularly used when the genset controller has to monitor a genset aimed for charging a set of external batteries. DST2700 controls the voltage of a set of external batteries and, in case of the voltage drops under a settable value, starts the stand-by genset which works
to recharge the batteries. DST2700, checking either voltage and current of batteries, stops the genset when proper values are reached. Actually this version of DST2700 is available for Single phase gensets only.
