Generator Protections

Underfrequency (81U), Overfrequency (81O), Undervoltage (27), Overvoltage (59), Power direction (32), Time dependent overcurrent (51), Instantane-ous overcurrent (50), Phase sequence, Current and Voltage unbalance, rated conditions failure.

Input, Output and Auxiliary functions

Embedded alarm horn. 6 programmable digital inputs. 2 relays (8A) outputs. 2 relays (40A) fuel valve and start

Interface

N.1 RS232 serial port with MODBUS RTU protocol. CAN interface with J1939 protocol for engine man-agement (optional)

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.
