  • 1.Overview

    Y-701/Y-702 series Dual-Automatic Transfer Switch Controller is an ideal ATS controller which equipped with Microprocessor Measuring unit, Programmable Output unit, Communication unit(only 702),Indicator Display(701 NORMAL,702 LED) function, adjustable Conversion Delay function, adjustable working models and Intelligent Power Module to reduce the risk of man-made operation.
    Due to the core is made up of microprocessor, Y-701/Y-702 series controller can detects any tiny changes(over-voltage,under-voltage and lacking phase) of the circuit and output the passive switch quantity signal.

     

    2.Features
    2.1 Microcontroller-based measurement and control system with true RMS calculation for thebasic parameters of the power grid;
    2.2 Adjustable transfer delay and operation modes for various applications;
    2.3 LEDs indicate the operational status;
    2.4Equipped with programmable input and output interfaces;
    2.5 Passive fire signal;
    2.6 RS-485 communication interface;
    2.7 Protection level:IP50.

     

    3.Operating Environment
    3.1 Installation site:The altitude should match the TSE-specified usage altitude.
    3.2 Pollution level:Level 3.With no explosive hazards,corrosive gases,liquids,or conductivedust that may damage metal components or insulation in the surrounding air.
    3.3 Ambient air temperature:-5°C~+40℃,with an average temperature within 24 hours notexceeding+35℃.
    3.4 Humidity:When the maximum temperature is +40°℃,the relative humidity should notexceed 50%.Higher humidity is permissible at lower temperatures(e.g.,up to 90%at+20℃).Special measures should be taken for occasional condensation due totemperature changes.
    3.5 If these conditions above are not met,please consult our company for further solutions.
