DAR70575PU is a UL-approved, normally open high-voltage relay from the DA(UL) series designed for high-reliability applications requiring excellent isolation and switching performance. The relay features 7.5 kV isolation across contacts with rhodium contact material, delivering low contact resistance of 50 mO (typical 15 mO) and a maximum switching voltage of 1000 V DC or AC peak with a maximum switching current of 3 A. Operating with a 5 V DC coil, the relay has a must-operate voltage of 3.7 V and a must-release voltage of 0.5 V, with operate and release times of 3.0 ms and 2.0 ms respectively when a diode is fitted. The relay is suitable for demanding applications such as cardiac defibrillators, test equipment, and high-voltage power supplies, where high isolation voltages and low contact resistance are essential for reliable performance.
