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.
