Многоканальный монитор с интеллектуальным управлением KM1
Многоканальный монитор с интеллектуальным управлением
Платформа KM1 позволяет визуализировать потребление электроэнергии при использовании на задней панели с помощью концепции "ведущий-ведомый". К ведущему блоку можно подключить до четырех ведомых для осуществления одновременного измерения электрических и неэлектрических параметров.
- Существенно сокращено время установки.
- Пространство для установки уменьшено на 24% по сравнению с традиционными средствами для контроля.
- Уменьшено количество устройств: с помощью одной платформы можно измерить до 36 контуров.
- Количество проводных соединений также уменьшено благодаря высокоскоростному соединению внутренней шины Innerbus и напряжению источника питания ведущего блока.
- Настраиваемая платформа для любой области применения
- Удобная классификация объединенной энергосистемы благодаря настраиваемым внутренним пороговым значениям
- Высокоточные измерения даже для токов ниже 5% от номинального значения.
- Отсутствие необходимости использовать трансформатор напряжения / До 7 импульсных выходов для сбора данных, в том числе, о неэлектрических параметрах
- Оснащен входом температуры
- Бесплатная программа для конфигурации KM//KE1
- Двойной мониторинг системы с помощью одного блока
