The DAT200-12 is a high-voltage reed relay from the D-HR series, designed for applications requiring high insulation resistance and reliable switching. It operates with a 12V DC coil and provides 10kV of isolation across its normally open (SPNO) tungsten contacts. The relay can switch up to 7000V at a maximum power of 50W, with a maximum carry current of 3A. Key features include a minimum insulation resistance of 1x10^14 Ω, a 3.0 ms operate time, and a maximum contact resistance of 250 mΩ. Its robust characteristics make it ideal for sensitive, high-reliability applications such as test equipment, cardiac defibrillators, and high-voltage power supplies.
