Описание в каталоге: CM-LWN Motor load monitor, 2x1c/o L1-L2-L3=500VAC, L1/k-L1/l=5A,380-440VAC
Длинное описание: The CM-LWN relay is from the CM motor load monitors range. This relay operates with a rated control supply voltage of 380-440 V AC, has a 2 x 1 c/o (SPDT) output with contacts rated at 250 V / 4 A and works according to the closed-circuit principle. Its measuring principle is based on the evaluation of the phase shift between the voltage and the current in one phase of single- or three-phase asynchronous motors (squirrel cage). The measuring circuit is designed for measuring voltages of 110-500 V AC and measuring currents of 0.5-5 A AC. The window (over- and underload) monitoring allows setting of two individual threshold values, one for maximum load and one for minimim load. The hysteresis is fixed at 4 ° related to the phase angle. The tripping delay is adjustable within a range of 0.2 to 2 s and the start-up delay within a range of 0.3 to 30 s. A sealable transparent cover for protection against unauthorized changes is available as accessory.

Эффективный контроль нагрузки асинхронного двигателя
Реле контроля нагрузки двигателя используются для контроля нагрузки однофазных и трехфазных асинхронных двигателей. Анализ угла сдвига cos ϕ является наиболее точным и экономичным способом контроля по сравнению с другими традиционными методами измерения (например, по сравнению с датчиками давления и системами измерения тока). Реле измеряет напряжение всех трех фаз, ток одной фазы и рассчитывает угол фазы (cos ϕ) между ними для оценки состояния двигателя.
Преимущества
- Сокращение времени простоев
- Простота ввода в эксплуатацию
- Простота обслуживания
Возможности
- Один модуль для мониторинга недостаточной и избыточной нагрузки на основе анализа угла сдвига cos ϕ
- Регулируемая задержка пуска 0,3–30 с
- Измерение токов до 20 A напрямую
- Регулируемая задержка срабатывания 0,2–2 с
- Контроль однофазных или трехфазных сетей
- 2 x 1 переключающий контакт, модель замкнутой цепи
