Circuit protection devices are used to protect electronic components from unwanted transients such as current and voltage surges, electrostatic discharge (ESD), lightning, spikes and other signals that can imperil the operation or damage the component.
Ground fault relays protect electrical equipment from ground faults. A ground fault is an unintentional current path between a current-carrying conductor and a grounded surface.
High voltage relays are used to transfer power for high voltage and high frequency applications. They are heavily insulated and consist of strong materials to increase contact life.
Power supplies are devices that produce AC or DC power. This grouping includes current sources, DC power supplies, AC-DC adapters, DC-DC converters, AC power sources, and DC-AC inverters.
Power transformers convert power-level voltages from one level or phase configuration to another. They can include features for electrical isolation, power distribution, and control and instrumentation applications.
Voltage regulators are power converters that provide voltage control capabilities. They accept a voltage that varies over a given range and generate an output voltage that does not vary.
