High voltage relay
A high voltage relay is used to operate at high voltages. Relays are used in a number of different applications, such as instrumentation systems and process control. Relays may be electromechanical, electrical, or electronic in nature. Electromechanical switching relays operates by passing a current through a wire wound coil to create a magnetic field which is used to close the relay. Thus, relays act as electromechanical switches. The relay is opened and/or closed by energizing an electromagnet to either attract or repel a metal contact on a movable strip of metal. Electromechanical relays are the standard means for switching high frequency signals. Compared with over solid-state relays, electromechanical relays have the lower ON resistance (when the relay contacts are closed) and higher isolation (when the contacts are open) at high frequencies. However, electromechanical relays are large, noisy, require relatively large power to operate, and are slow to operate. Advances in solid state switching technology have made possible the replacement of many electromechanical switching and relay assemblies. Solid state devices provide the power control systems in which they are incorporated with long life, quiet operation and other associated advantages.

Miniature High Voltage Reed Relays In the modern world, there is a constant drive to reduce size yet increase the performance of almost every type of electronic component. With that in mind, MEDER electronic has introduced two new high voltage Reed Relays for PCB mounting. These miniature high voltage relays take up only 40x15x13.5mm board area. These high voltage relays offer a switching voltage of 1 kVDC with a 4 kVDC or 6-kVDC option across the contacts.
MEDER electronic features a full line of reed relays offering high voltage and high power configurations for PCB mount or free-standing applications. MEDER High Voltage Reed Relays are designed to switch high voltages, stand off even higher voltages, and carry very high current levels.
