The ANLY EP4-1 Digital Voltage Protective Relay is a versatile device designed to monitor and protect electrical systems from various voltage anomalies. It is suitable for a wide range of applications, including those requiring particular safety or in important facilities, where fail-safe mechanisms, redundancy checks, and periodic inspections are recommended. The device is rated at Class II.

Function Description:

The EP4-1 relay continuously monitors the voltage of an electrical system and provides protection against over-voltage, under-voltage, phase reversal, unbalance, and phase loss. It features a clear display that shows real-time phase-to-phase voltages, setting values, and fault indications. Users can configure specific voltage thresholds and tripping delays for both over-voltage and under-voltage conditions. The device also includes DIP switches for enabling or disabling phase reversal protection, unbalance protection, and selecting auto-reset or manual-reset modes, along with auto-reset delay settings. In the event of a fault, the relay activates its output contacts to signal the anomaly, allowing for system shutdown or alarm activation. The timing chart illustrates the operational sequence and response times for various fault conditions, including over-voltage, under-voltage, phase loss, reverse phase, and unbalance.
