The DAR72410FU is a UL-approved, normally open high-voltage relay from the DA(UL) series designed for high-reliability applications requiring very high isolation voltages. This relay features 10kV isolation across contacts with tungsten contact material, enabling switching of high voltages up to 7000V DC or AC peak at a maximum current of 2A. The relay operates with a 24V DC coil, requiring a must-operate voltage of 20V and a must-release voltage of 4V, with operate and release times of 3.0ms and 2.0ms respectively when a diode is fitted. The flying lead connection style with UL3239 22AWG cable (20kV rated) provides flexible high-voltage connections for PCB mounting, making it suitable for applications such as cardiac defibrillators, test equipment, and high-voltage power supplies where excellent isolation and reliability are critical.
