Реле контроля Omron K8DT-PZ
Трехфазное реле контроля напряжения, перекоса и чередования фаз и потери фазы для защиты электродвигателей и другого оборудования от повреждений из-за нестабильности напряжения в системе электропитания. Обнаружение повышенного и пониженного напряжения, асимметрии напряжений, нарушения порядка чередования фаз и потери фазы в трехфазной линии питания.
- Обнаружение потери фазы во время работы двигателя
- Переключение номинального напряжения с помощью DIP-переключателя для поддержки широкого спектра 3-фазных 3-проводных систем
- Повышенная устойчивость к помехам инверторов
- Ширина 17,5 мм — экономия пространства в шкафу управления
- Технология Push-in plus упрощает подключение проводов
- Соответствие UL упрощает ввоз в Северную Америку
- Отверстия на два провода в каждой клемме для удобного подключения других устройств
- Добавлены модели с высоконадежными транзисторными выходами
- Соответствие Директиве RoHS
