HAT821 Dual Power Bus Tie controller is intelligent bus-tie dual-power switchover module with configurable function, automatic measurement, LCD display, and digital communication. It combines digitization, intelligence and networking. Automatic measurement and control can reduce incorrect operation, which is an ideal option for dual-power bus-tie switchover products.

The powerful Microprocessor contained within the unit allows for precision voltage (2-way 3-phase) measuring and make accurate judgment and the corresponding volt free digital output port will active when there is over/under voltage, over/under frequency, loss of phase, phase sequence wrong and other abnormal condition occurs. 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, etc.

PERFORMANCE AND CHARACTERISTICS

1.    4.3 inchs solid color 240x128 LCD display with white backlight, multilingual interface (including English, simplified Chinese or other languages), push-button operation;

3.    Display S1/S2 total close times;
4.    Display load 1 and load 2 present continuous power supply time and total power supply time;
5.    Display S1/S2 total power supply time;
6.    Over/under voltage, over/under frequency, loss of phase, phase sequence wrong protection;
7.    Real-time clock (RTC); event log function (event log can record 200 items circularly);
8.    Suitable for various AC systems (3- phase 4-wire, 3-phase 3-wire, single-phase 2-wire, and 2-phase 3-wire);
9.    Simultaneously control the closing and opening of the two-way CB switch and the bus-tie CB switch to simplify the control system;
10.    For Stored-Energy type ATS, its close relay will active after the PF Input is active;
11.    Automatic/Manual mode. In manual mode, can force the switch to close or open;
12.    6 buttons on the panel to manually control breaker switch easily;
13.    With breaker re-close function;
14.    Closing output signal can be set as on intervals or as continuous output, which suitable for CB breaker or CC contactor;
15.    All parameters can be set on site. Passwords authentication ensures authorized staff operation only;
16.    Applicable for 2 isolated neutral line;
17.    Enabling switch power supply LO/NO output to provide power for switching coil;
18.    Widely DC power supply range allows the controller can bear instantaneous 80V DC input;
