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 laser warning symbol. Laser radiation safety is the safe design, use and implementation of lasers to minimize the risk of laser accidents, especially those involving eye injuries. Since even relatively small amounts of laser light can lead to permanent eye injuries, the sale and usage of lasers is typically subject to government regulations.
Directional IRCM, or DIRCM, allows for a countermeasures laser to be targeted directly at an incoming IR threat.This makes possible a more powerful and effective defense than previous, non-directional infrared countermeasures, as the threat is directly addressed rather than the system essentially painting an area with IR disruption, which results in a weaker signal in any given direction.
Companies advise against connecting devices like copiers, laser printers, or space heaters to a UPS, as these can overload the device. Instead, use a separate surge protector.
This is the most commonly used surge waveform for most applications, often referred to as a "1.2/50-8/20 μs" surge. Alternatively, for outdoor telecommunication networks that experience a higher surge level, the standard also defines a more energetic generator with a 10/700 μs voltage waveform and a 5/320 μs current waveform.
[dubious – discuss] This feature provides better surge protection than a simple Zener diode and acts more like a gas-discharge tube replacement. Avalanche diodes have a small positive temperature coefficient of voltage, whereas diodes relying on the Zener effect have a negative temperature coefficient. [2] [dubious – discuss]
