Relee

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 relė skirta naudoti fotovoltinėse sistemose tinklo įtampos stebėsenai ir apsaugai. Ji gali apsaugoti nuo viršįtampio, įtampos trūkumo, fazių disbalanso, fazių sekos pažeidimų ir fazių praradimo, analizuodama kiekvienos fazės įtampą. Siūlo įvairias apsaugos funkcijas su reguliuojamomis reikšmėmis pagal konkrečius nacionalinius standartus ar atviro tipo konfigūraciją.
