• Collect and display 2-way 3-phase voltages, frequency, and phase sequence;
• Collect and display loading active power, reactive power, apparent power, power factor and current;
• Independent over current warning and trip alarm functions for S1 and S2;
• NEL trip function;
• isplay of accumulated active power, accumulated reactive power, accumulated close times, accumulated automatic transfer times, and mains outage transfer times for S1 and S2;
• Display of continuous power supply time, accumulated power supply time for S1 and S2, accumulated automatic transfer running time;
• For energy-accumulated switch, it has function of breaker close when switch PF (close is well prepared) signal is active;
• Functions of over voltage, under voltage, over frequency, under frequency, over current, loss of phase, and inverse phase sequence;
• Auto/Manual status switchover is set, and breaker close/open can be controlled manually in manual mode;
• All parameters can be configured on site, and it applies password verification, which can prevent non-professional mistake operation;
• Commissioning can be done on site manually to do start/stop operation of genset;
• Function of breaker re-close function;
• Close output can be pulse or continuous output;
• 2-way N wire isolated design;
• Real time clock display, event log function with recording cyclical 200 data;
• Scheduled detecting start/scheduled not start function for genset; it can be set to run for once, each month, or each week, and running with loading or not can also be set;
• It can control two gensets, realizing cyclical running, master running, and balanced time running;
• Wide range of DC power supply, which can bear max. 80V DC input transiently;
• AC power supply can be phase voltage (L, N), or wire voltage (L, L) with supply range: (90~576)V;
• Large space between AC input wire terminals, which can bear 625V voltage input;
• Loading end is live or not can be detected;
• 2 ways of RS485 isolated communication ports are set, which has remote control, remote communication, remote measurement, and remote regulation functions by ModBus-RTU communication protocol; it can also remote control genset start, stop, breaker close and open functions; munication, remote measurement, and remote regulation functions by ModBus-RTU communication protocol; it can also remote control genset start, stop, breaker close and open functions;
• Suitable for multiple AC system types (3-phase 4-line, 3-phase 3-line, 1-phase 2-line, 2-phase 3-line methods);
• Modular structure design, flame retarding ABS shell, pluggable connecting terminal, and embedded installation method, with compact structure and convenient installation.
