Product Overview:
HAT821SI Dual Power Bus Tie Controller is a medium voltage ATS module that integrates configurable function, automatic measurement, PT break detection, load stepwise transfer, LCD display and digital communication. It combines digitization, intelligence and networking, the automatic measurement and control process can reduce incorrect operation, which is an ideal option for dual power bus-tie transfer.

HAT821SI Dual Power Bus Tie Controller is composed of microprocessor as the core, which can precisely detect 2-way 3-phase incoming voltage, make accurate judgment for voltage abnormal situations (over/under voltage, over/under frequency, loss of phase, reverse phase sequence) and output passive control coil. With compact structure, advanced circuits, simple wiring and high reliability, it can be widely used in electrical automatic control system of electric power, telecom, petrochemical industry, mining, railways, municipal administration, data center, intelligent building and other industries.

PERFORMANCE AND CHARACTERISTICS
——System type can be set as: Mains - Mains, Mains - Gen, Gen - Mains;
——4.3-inch single color 240x128 LCD display with white backlight, multilingual display (including Simplified Chinese, English and others), push-button operation;
——Collect and display 2-way 3-phase voltage, current, phase sequence, frequency and voltage imbalance;
——Display 2-way active power, reactive power, apparent power, power factor and earth current;
——PT break detection function, whether PT wire is broken can be judged by measured voltage and current data, or PT break status can be obtained by digital input ports;
——Load switch stepwise transfer can realize the control of local and external. Up to 12 load switches of each way can be realized by local stepwise transfer control. The priority of each load switches can be set flexibly and the closing feedback status, operating position status, test position status and switch tripping status can be detected;
——Real-time detection of the load rate for 2 power supplies, intelligent loading and unloading can be performed according to the settings;
——6 16-way digital input modules and 4 16-way digital output modules can be extended by RS485 interface;
——Display S1/S2 total power supply time; display current duration and total duration of power supply for Load 1 & Load 2;
——Display total close times of QS1, QS2 and QTIE; phase sequence;
——Earth fault protection function;
——NEL trip function;
——Detection functions of over/under voltage, over/under frequency, loss of phase, reverse
——S1/S2 overcurrent warning or fault independent alarm function;
——Manual commissioning to achieve genset start/stop operation;
——Scheduled routing run & scheduled not run (can be set as genset start daily/weekly/monthly whether with load or not);
——Real-time clock (RTC);
——Event log function (event log can record 200 items circularly);
——With black box function, can record 5 events circularly, 60 detailed data of 50s before each event record, and 10s after each event record;
——Suitable for various AC systems (3-phase 4-wire, 3-phase 3-wire, single-phase 2-wire, and 2-phase 3-wire methods);
——Simultaneously control the closing and opening of the 2-way CB switch and the bus-tie CB switch to simplify the control system;
——For stored-energy type ATS, its can close after the PF input is active;
——Auto/Manual transfer, manually control the switch close or open in manual mode;
——Loop closing mode (sync. closing and parallel continuous running), and the reverse power detection function can realize the trip protection when reverse power occurs;
——Local mode. When it is active, controller only displays data parameters, switch transfer needs to be realized by external operation;
——Electric interlock release function, which is used for releasing electric interlock in switch parallel transfer;
——6 kinds of buttons on the panel to manually control switch easily;
——Breaker re-closing function;
——Closing output signa
