EVD Evolution


  • Общие характеристики

    Драйверы электронных ТРВ серии EVD Evolution — это новейшие драйверы последнего поколения, выпускаемые компанией CAREL для регулирования перегрева.

    В отличие от обычных драйверов EVD они поддерживают самые современные функции и получили новый графический терминал, который делает процесс настройки и работы с драйвером еще проще.

    Драйвер настолько прост в настройке, что при наличии графического дисплея весь процесс ввода в эксплуатацию ограничивается настройкой буквально четырех параметров (или всего трех параметров, если драйвер будет управлять вентилями Carel): тип хладагента, тип вентиля, тип датчика давления и управляемый агрегат (холодильная машина, холодильная витрина и т.д.). Все параметры находятся в экранном меню драйвера.

    Основные достоинства:

    • регулирование перегрева и защита от недостаточного перегрева, низкого давления и высокого давления
    • быстрый и простой ввод в эксплуатацию (достаточно настроить всего 4 параметра)
    • схема соединений выводится на дисплее драйвера
    • съемный жидкокристаллический дисплей, поддерживающий многоязычный интерфейс, справку по настройке параметров, единицы измерения СИ и британские
    • разграничение уровней доступа паролями
    • копирование параметров конфигурации с одного драйвера семейства EVD на другой (в памяти дисплея)
    • светодиодные индикаторы для контроля основных параметров
    • поддержка малопотребляющих логометрических датчиков давления со встроенным преобразователем и выходным сигналом тока 4 — 20мА (один датчик может использоваться несколькими драйверами)
    • второй цифровой вход для управления оттайкой
    • поддержка резервных датчиков

    Драйверы EVD Evolution в сочетании с электронными терморасширительными вентилями CAREL семейства ExV представляют собой готовую интегрированную систему управления для обеспечения оптимальной работы испарителей и сокращения расходов на электроэнергию.
