3PERFORMANCE AND CHARACTERISTICS
——System type can set as: S1 Mains S2 Mains, S1 Mains S2 Gen, S1 Gen S2 Mains, S1 Gen
S2 Gen;
——4.3 inchs solid color 240x128 pixel LCD display with white backlit, multilingual interface
(including English, Simplified Chinese and other languages), push-button operation;
——Collect and display voltage, frequency and phase sequence of 2-way 3-phase;
——Collect and display active power, reactive power, apparent power, power factor and current
of load;
——Display position of main switch (working, testing, insulated), and position of bypass switch
(working, testing, insulated);
——Independent S1/S2 over current warning or trip alarm functions;
——NEL (Non-essential Load) trip function;
——Display S1/S2 total kW energy, total kvar energy;
——Display S1/S2 accumulated close times of main switch and bypass switch;
——Display continuous power supply time at present and last time, and S1/S2 total power supply
time;
——Can realize synchronous switchover function, and display voltage difference, frequency
difference and phase difference of 2 circuits;
——For energy-accumulated ATS, it shall close when switch PF(close is prepared well) signal is
active;
——Over/under voltage, over/under frequency, over current, loss of phase, inverse phase
sequence protection functions;
——Automatic/Manual mode switchover; In manual mode, close or open can be controlled
manually;
——All parameters can be set on site. Password validation is applied to prevent wrong operations
for non-professionals;
——The genset can be tested manually on site to achieve start/stop operation;
——Re-close function of main switch and bypass switch in auto mode when power outage occurs;
——Applicable for single bypass, double bypass and alternate dual spare bypass switch;
——Applicable for bypass switch of manual control and remote control
——2-way N wire isolated design;
——Real-time clock (RTC); event log function, which can record e 200 items circularly;
——Black box record function, which can record 5 events circularly, 60 data of 50s before each
event record, and 10s after each event record;
——Scheduled routing start & scheduled not start function for the genset, which can be set as
start once a day/week/month; and running with load or not;
——Can control two generators to work in the mode of circular running, master running and
balanced running;
——Wide DC power supply range, which allows the controller to bear instantaneous 80V DC
current input;
——Large terminal space allows the controller to bear maximum 625V AC voltage input;
——Dual isolated RS485 communication interface, having the functions of "remote control,
remote measuring, remote communication, remote regulating" by the ModBus-RTU
communication protocol, which can remotely start/stop the genset and control the breaker to
