Relays

The Ex9JP F-1 is a specialized Frequency Monitoring Relay designed for monitoring AC frequencies in critical applications such as photovoltaic stations and generators. It supports 50/60/400 Hz frequencies and allows adjustable frequency thresholds (80–120% of nominal frequency), providing adaptability for diff erent power systems. Key features include adjustable diff erence (0.5–5% of Fn) and delay levels (0.5–10 seconds), enabling precise control over frequency variations. The device operates within a 161-500 V AC voltage range and includes 2 change-over contacts, off ering fl exibility in connections. Its user-friendly design, with front-panel switches for settings adjustments, makes it suitable for complex power monitoring tasks.

Ex9JP-G seirerelė on mõeldud kasutamiseks päikeseenergiapaigaldistes, et jälgida ja kaitsta elektrivõrku ühendatud vooluahelaid. See pakub kaitset ülepingete, alapingete, faaside tasakaalustamatuse, faasijärjestuse ja faasi kadumise eest, jälgides iga faasi pinget. Relė toetab erinevaid kaitsekombinatsioone, mille väärtusi saab reguleerida vastavalt riiklikele standarditele või vabalt seadistatavatele seadetele.
