РЕЛЕ КОНТРОЛЯ ПРЕВЫШЕНИЯ ИЛИ ПОНИЖЕНИЯ COS-PHI И АКТИВНОГО ТОКА (ЦИФРОВОЕ ПАРАМЕТРИРОВАНИЕ), НОМИНАЛЬНОЕ ПИТАЮЩЕЕ НАПРЯЖЕНИЕ ЦЕПИ УПРАВЛЕНИЯ ОТ 90 ДО 690 В AC 50 ДО 60 ГЦ (ВНУТРЕННЕЕ ПИТАНИЯ ЦЕПИ ИЗМЕРЕНИЯ), ЗАДЕРЖКА ОТКЛЮЧЕНИЯ 0.1 ДО 20 С., ГИСТЕРЕЗИС AT (IRES) 0.1 ДО 2A, 2 ПЕРЕКИДНЫХ КОНТАКТА, АВТО- ИЛИ РУЧНОЙ СБРОС, ПРУЖИННЫЕ КЛЕММЫ Cos phi monitoring relay with digital setting SIRIUS 3UG4 for monitoring the power factor and active current for overshooting, e.g. in the event of soiled filter systems, or for undershooting, e.g. in the event of a torn V-belt or pump idling.
Worldwide use thanks to wide voltage range and international certificates. The relay monitors even small single-phase motors with a no-load current below 0.5 A. Implicit monitoring for cable break and phase failure is also possible. The power factor or active current measuring principle can be selected. Less space required in the control cabinet thanks to slim design. Reliable diagnostics thanks to display of ACTUAL value and status messages. All versions with removable terminals.
In addition to screw terminals, all the devices are also available with spring-type terminals for fast, maintenance-free and vibration-proof connection. They are optionally available with IO-Link.
The comprehensive range of accessories, such as unit labeling plates, push-in lugs and cover caps, is standardized for all relays.
SIRIUS relays - one range for every application.
