The Y-800 busbar controller is used to control three frame circuit breakers, realize the conversion of two power supplies and the busbar connection on the load side.It is based on microprocessor, which can detect the voltage of two three-phase incoming lines accurately, make accurate judgment on the voltage abnormality (overvoltage, undervoltage, over frequency, under frequency, missing phase, reverse phase sequence), complete the power conversion and the connection and disconnection of the bus on the load side according to the given logic, and output the passive control switch to complete the control of the load, display the system status and other functions.The controller is equipped with electrical interlock accessories, which cooperate with mechanical interlock to realize redundant interlock system and improve the reliability of operation.The product has compact structure, simple wiring and high reliability. It can be widely used in electrical automatic control systems of power, telecommunications, petrochemical, mining, rail transit, municipal, data center, intelligent building and other industries.

 

 

  — The system type can be configured as mains-to-mains, mains-to-generators, or generators-to-mains;

 —A monochrome 4.3-inch LCD display with 240x160 resolution, white backlight, and multilingual support (Simplified Chinese and English), featuring touch-sensitive buttons for operation.

 — Collect and display two-channel three-phase voltage, current, phase sequence, frequency, and voltage imbalance;

 --can display two active power, reactive power, apparent power, power factor;

 —Displays the cumulative power supply duration of S1/S2, along with the current and total power consumption times for Load 1 and Load 2.

 —Displays cumulative closing counts for QS1, QS2, and QTIE;

 —overvoltage, under-voltage, phase missing, reverse phase sequence, over-frequency, under-frequency detection function;

 — Independent alarm for S1/S2 overcurrent warning;

 --With manual test function, it can start and stop the generator set;

 --It can be set to start the generator set for timed inspection, and can be set to run monthly, weekly or daily, and can be set to run with load;

 --Real-time clock display;

 — With historical recording capability, it can record up to 100 data entries in a loop;

 — Compatible with multiple communication system configurations (three-phase four-wire, three-phase three-wire, single-phase two-wire, and two-phase three-wire modes);

 —can control the closing and opening of two frame circuit breakers and the busbar frame circuit breaker at the same time, simplify the control system;

 — Features automatic/manual mode switching. In manual mode, the switch can be manually operated to close or open.

 --It has the function of electrical interlock release, which is used to release the electrical interlock when switching in parallel;

 — The panel features six switch buttons for easy manual operation;

 --With switch reclosing function;

 --The closing output can be set as pulse or continuous output, which can be applied to the circuit breaker or contactor;

 — All parameters are field-programmable and password-protected to prevent accidental operation by non-professionals;

 --Two N lines separated design;

 — The DC power supply range is extremely wide, and can instantly withstand up to 60V DC input;

 — The AC input terminal has a large spacing, and can withstand up to 625V AC voltage input;

 — Equipped with a single RS485 isolated communication interface, it operates under the Modbus-RTU protocol and supports remote control functions including signal transmission, measurement, and adjustment. The system enables remote operation of generator sets for startup/shutdown and ATS circuit switching.
