Self-learning mains disconnection relay. 1 NO contact not potential free 16A/250V AC
Self-learning mains disconnection relay. Standby loss 0.8 watt only. State-of-the-art hybrid technology combines advantages of nonwearing electronic control with high capacity of special relays. The mains disconnection relay disconnects the power supply once all series connected loads are turned off, thus preventing any electromagnetic interference fields from occurring. Small loads up to 200mA, are acceptable and, once major loads are disconnected, they do not prevent field disconnection. The limit is taught-in automatically by the mains disconnection relay using a patented method so you need not set the limit manually. Loads drawing more than 200mA are consistently defined as loads which should cause the line power to be connected. As long as no major load is turned on, one pole of the monitored circuit remains isolated from the mains. Neutral and earth are connected continuously to avoid acting as an aerial. A DC voltage with an extremely low residual ripple is applied for monitoring. Therefore, it is prohibited to bridge the relay contact, which would ultimately cause device failure. When a load is turned on, the mains disconnection switch connects the monitored phase after approx. 1 sec and the LED lights red.
