Controller HAT553 Dual Power Automatic Switching Controller

Electronic Engine ControlDESCRIPTION:HAT552/HAT553 dual power automatic switching controller is a dual power switching module with programmable function, automatic measurement, display and digital communication. It integrates digitization, intelligence, and networking, and automates the measurement and control process, reducing human error. It is an ideal product for dual-circuit power switching. HAT552 is suitable for non-breaking position switches, and HAT553 is suitable for non-breaking position, one breaking position and two breaking position switches.The HAT552/HAT553 dual power automatic switching controller is composed of a microprocessor as the core, which can accurately detect the two-way three-phase voltage, and can detect the abnormal voltage (overvoltage, undervoltage, overfrequency, underfrequency, phase loss, reverse phase) order) to make accurate judgments and control the output. Its compact structure, advanced circuit, simple wiring and high reliability can be widely used in electrical automatic control systems in electric power, post and telecommunications, petroleum, coal, metallurgy, railway, municipal, intelligent building and other industries.Performance and FeaturesThe system type can be set to mains-power generation, power generation-mains power, and mains-mains power; is 132x64, with backlight, two languages (Simplified Chinese, English) display, touch button operation;Collect and display two-way three-phase voltage, frequency and phase sequence;It has the display of cumulative closing times of A power supply/B power supply;It has the display of current continuous power supply time and accumulated power supply time of A power supply/B power supply;It has the functions of overvoltage, undervoltage, overfrequency, underfrequency, phase loss and reverse phase sequence;With automatic/manual state switching, in manual mode, the switch can be manually controlled to close and open;All parameters are field programmable and password verification is adopted to prevent misoperation by non-professionals;On-site manual test machine can be used to start and stop the generator set;With switch reclosing function;The closing output can be set to pulse or continuous output;Two-way N line separation design;Real-time clock display, with historical record function, can record 50 pieces of data cyclically;It has the function of regular inspection and startup of the generator set, which can be set to run once, monthly or weekly, and whether to run with load or not;AC power supply can be phase voltage (L, N), power supply range: (170~277)V.Equipped with one RS485 isolated communication interface, using the ModBus-RTU communication protocol, it has the functions of remote control, remote signaling, remote measurement, and remote adjustment.Suitable for a variety of AC system types (three-phase four-wire, single-phase two-wire, two-phase three-wire mode);Modular structure design, flame retardant ABS shell, pluggable terminals, embedded installation, compact structure, easy installation.monitor:(132*64)controller language:Chinese EnglishCommunication system:1P2W/2P3W/3P4WProgrammable input port:3Programmable output port:4AC frequency:50/60HzVoltage frequency protection:haveMonitoring interface:RS485programming interface:RS485Real Time Clock:have test machine:haveSuitable for switch type:two-stageDimensions (mm):139*120*50Installation size (mm):130*111Operating temperature:(-25~+70)Pictures:
