Product Overview:
HAT880 Series Dual Power Bypass ATS Controller is an intelligent dual power bypass switch module which integrates programmable function with automatic measurement, LCD display and digital communication. It is with qualities of digitalization, intelligence, and network. Meansurement and control automation is realized for reducing human operation mistakes, so it is the ideal device for dual power bypass switch.

HAT880 Series Dual Power Bypass ATS Controller is composed of micro-processor, which is the core in the controller, and can precisely detect 2-way 3-phase power, making correct judgment for abnormal power statuses (over voltage, under voltage, loss of phase, over frequency, under frequency) and outputting free voltage control signals. After overall consideration about its bypass switch application, it can be used directly on single and dual bypass switches, and manual or remote control switches. It is with compact structure, advanced circuit, simple wiring, and high reliability, and can be widely used in electrics, telecommunications, petroleum, coal, metallurgy, railway, municipal administration, intelligent building fields, electric installations, servicer power supply and debug system.


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 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 close or open;

Suitable for multiples of AC systems (3-phase 4-wire, 3-phase 3-wire, single-phase 2-wire, and 2-phase 3-wire);

Modular design, antiflaming ABS plastic shell, pluggable terminals, built-in mounting,compact structure and easy installation.
