2. Surge protector - Wikipedia

   en.wikipedia.org/wiki/Surge_protector

   Surge Protection Device (SPD) for installation in a low-voltage distribution board. A surge protector (or spike suppressor, surge suppressor, surge diverter, [1] surge protection device (SPD), transient voltage suppressor (TVS) or transient voltage surge suppressor (TVSS)) is an appliance or device intended to protect electrical devices in alternating current (AC) circuits from voltage spikes ...

   [2] [5] The "8/20 μs" generator is designed for surge arrester testing, and produces a high-current surge into a low-impedance load. [2] On the other hand, modern electronic devices can be high and low-impedance loads simultaneously due to non-linear devices, protection circuits, and arcing in a dielectric breakdown.

4. Transient-voltage-suppression diode - Wikipedia

   en.wikipedia.org/wiki/Transient-voltage...

   The device operates by shunting excess current when the induced voltage exceeds the avalanche breakdown potential. It is a clamping device, suppressing all overvoltages above its breakdown voltage. It automatically resets when the overvoltage goes away, but absorbs much more of the transient energy internally than a similarly rated crowbar device.

5. Voltage spike - Wikipedia

   en.wikipedia.org/wiki/Voltage_spike

   Surge protector – Protects electrical devices from voltage spikes; Flyback diode – Voltage-spike stopping diode across an inductor - a device to channel inductive spikes back through the coil producing them; Voltage sag – Short-duration reduction in the voltage of an electric power distribution system

6. Uninterruptible power supply - Wikipedia

   en.wikipedia.org/wiki/Uninterruptible_power_supply

   The offline/standby UPS offers only the most basic features, providing surge protection and battery backup. The protected equipment is normally connected directly to incoming utility power. When the incoming voltage falls below or rises above a predetermined level the UPS turns on its internal DC-AC inverter circuitry, which is powered from an ...

7. Power strip - Wikipedia

   en.wikipedia.org/wiki/Power_strip

   A North American power strip with two USB power ports that includes a built in surge protector. A power strip (also known as a multi-socket, power board and many other variations [a]) is a block of electrical sockets that attaches to the end of a flexible cable (typically with a mains plug on the other end), allowing multiple electrical devices to be powered from a single electrical socket.
