DBT70510U is a UL approved normally closed high voltage reed relay featuring 5kV isolation across contacts and tungsten contact material. It utilizes high vacuum reed switches capable of switching voltages up to 3500V DC/AC peak with a maximum switching power of 50W. The relay operates with a 5V DC coil, requiring a must operate voltage of 3.7V DC and has a coil resistance of 38O. With an operating temperature range of -20°C to +70°C and contact-to-coil isolation of 17kV, this relay is suitable for high reliability applications such as cardiac defibrillators, test equipment, and high voltage power supplies.
