High Voltage Reed Relay Application/Selection Guide
High voltage test equipment:
In high voltage test equipment, high load voltage reed relays are often used for switching high voltage signals for testing electronic components and systems. For example, in a hipot tester, a high voltage reed relay is used to switch the high voltage output to the test object. Similarly, in a partial discharge (PD) test system, high voltage reed relays are used to switch the high voltage pulses to the test object.
Medical equipment
High load voltage reed relays are commonly used in medical equipment to switch high voltage signals, particularly in electroconvulsive therapy (ECT) devices. In ECT devices, a high voltage reed relay is used to switch the high voltage pulse to the patient's brain. High voltage reed relays are also used in other medical devices such as defibrillators and laser systems.
Power switching
High load voltage reed relays are used for power switching in various applications. For example, in a high voltage power supply, a high voltage reed relay can be used to switch the high voltage output to the load. In a power distribution system, high voltage reed relays can be used to switch high voltage signals to different loads.
Automotive electronics
High load voltage reed relays are used in automotive electronics for switching high voltage signals. For example, in electric vehicle charging systems, high voltage reed relays are used to switch the high voltage power to the battery. High voltage reed relays are also used in other automotive applications such as ignition systems and lighting systems.
Aerospace and defense
High load voltage reed relays are used in aerospace and defense applications for switching high voltage signals. For example, in radar systems, high voltage reed relays are used to switch the high voltage signals to the antenna. Similarly, in electronic warfare systems and missile guidance systems, high voltage reed relays are used for switching high voltage signals.
