Performance and Features

*The system type can be set to mains-mains-power generation, mains-mains-mains power, mains-power-generation-power generation, etc.

*Monochrome 4.3-inch large-screen LCD liquid crystal display, 240x128 pixels, white backlight, multi-language (simplified Chinese, English, traditional Chinese) display, touch button operation;

* Collect and display three-way three-phase voltage, frequency and phase;

* Collect and display load active power, reactive power, apparent power, power factor and current;

* With S1/S2/S3 independent overcurrent warning or trip alarm function;

* With non-important load NEL tripping function;

* With S1/S2/S3 cumulative active energy, cumulative reactive energy, cumulative closing times display;

* With the current continuous power supply time and S1/S2/S3 cumulative power supply time display;

*For the energy storage switch, you can wait for the switch PF (ready to close) signal to be valid before closing;

* With overvoltage, undervoltage, overfrequency, underfrequency, overcurrent, lack of phase, reverse phase sequence functions;

* With automatic/manual state switching, in manual mode, the switch can be manually controlled to close and open;

*All parameters are programmable on site, and password verification is adopted to prevent non-professionals from misoperation;

*On-site manual test machine can be used to start and stop the generator set; 

* With switch reclosing function;

*Close output can be set to pulse or continuous output;

*Three-way N-line separation design;

* Real-time clock display, with historical record function, can record 200 pieces of data cyclically;

* It has the function of timing on/off of the generator set, which can be set to run once, monthly or weekly, and can be set to run with load or not;

*It can control two generator sets to realize cyclic operation, main operation and balanced time operation;

* The DC power supply range is extremely wide, and can withstand up to 80V DC input instantly; 

*The AC input terminals have large spacing and can withstand voltage input up to 625V;

* Equipped with two-way RS485 isolated communication interface, using ModBus-RTU communication protocol, with remote control, remote signaling, remote measurement, remote adjustment functions, remote control of generator set start, stop, remote switch closing and opening functions;

*Suitable for a variety of AC system types (three-phase four-wire, three-phase three-wire, single-phase two-wire, two-phase three-wire mode);

* Modular structure design, flame retardant ABS shell, pluggable terminals, embedded installation, compact structure, easy installation.
