Characteristics
D Series
15kV, 50W
Capable of withstanding voltages up to 15kV, the D-series High Voltage Reed
Relay is suitable for high reliability applications such as cardiac defibrillators,
test equipment and high voltage power supplies. Two contact materials are
available for low contact resistance or power switching applications.
Standard coil voltages of 5, 12 and 24 volts are available with form A and B
contact configurations.
The D-series, range is now available with a new panel mounting option via nylon
studs, as well as a choice of electrical connection methods (solder turret tag and
flying lead) complementing the standard PCB `through-hole' device. Choose the
most appropriate device for your application using the part numbering system
below.
