Product Overview:
HAT820 series dual power ATS controller is an intelligent dual-power switchover module with configurable function, automatic measurement, LCD display, and digital communication. It combines digitization, intelligence and networking together. Measurement and control process can be conducted automatically, which reduces artificial operating mistakes, so that it is the ideal option for dual-power switchover products.

HAT820 series dual power ATS controller is composed by the powerful microprocessor in the core, which can precisely measure the voltages (2-way 3-phase) and make accurate decision for abnormal voltages (overvoltage, undervoltage, overfrequency, underfrequency, phase loss, reverse phase sequence), and putout power-off control digital signal. It has compact structure, advanced circuits, simple wiring and high reliability, and can be widely used in electrical automatic control system of electric power, telecommunications, petroleum, coal, metallurgy, railways, municipal administration, intelligent building and etc.


System type can be set as Mains-Power Generation, Power Generation-Mains, Mains-Mains, Power Generation-Power Generation;

4.3-inch large LCD Display of single color, 240x128 pixel with white backlight, multiple language display (Simplified Chinese, Engligh, and Other), default language for Other is Traditional Chinese, and tuch-button operation;

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;

Display 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;

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.
