Electric power quality – Measurement of power meeting specifications 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
Around 1968, Kloss quit KLH to develop a low-cost projection television, but had trouble financing the leading-edge research and development that was still required.To earn some money, he decided to build a high-performance low-cost dual driver speaker system with 10-inch (25 cm) woofer called simply The Advent Loudspeaker (later given the retronym the Larger Advent, after introduction of The ...
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 ...
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.
Power outages are categorized into three different phenomena, relating to the duration and effect of the outage: A transient fault is a loss of power typically caused by a fault on a power line, e.g. a short circuit or flashover. Power is automatically restored once the fault is cleared. A brownout is a drop in voltage in an electrical power ...
Information was available by over-the-air TV and radio reception for those who were equipped to receive TV and/or audio in that way. The blackout affected communications well outside the immediate area of power outage. The New Jersey–based internet operations of Advance Publications were among those knocked out by the blackout.
The white van speaker scam is a scam sales technique in which a con artist makes a buyer believe they are getting a good price on home entertainment products. Often a con artist will buy inexpensive, generic speakers [1] and convince potential buyers that they are premium products worth hundreds or thousands of dollars, offering them for sale at a price that the buyer thinks is heavily ...
Susceptibility of electronic equipment to these other electric power disturbances is defined by other aspects of the system design, either inside the equipment itself or externally by means such as a UPS, a voltage regulator or a surge protector with built-in overvoltage protection (which typically consists of a voltage-sensing circuit and a ...
