power limiter

power limiter

An engine protection device designed to prevent overstressing the engine because of excessive compressor outlet pressure during high-speed low-altitude running. When the compressor outlet pressure reaches its maximum value, that pressure is reduced by bleeding off air pressure from the acceleration control unit.

New features include a major system rewrite to the audio engine, introducing a new lower-latency clipper for both FM and AM; a new, fully rewritten streaming engine that now supports Shoutcast 2, FLAC and lossless streaming; an integrated internal stream server; phase correction with mono bass that reduces multipath distortion; expanded SNMP features; shared processing path for AM+HD units; improved BS.412 MPX power limiter; and seamless preset switching, even between presets with major structural differences.
He explained, "One alternative is to incorporate a power limiter into the switch design or get an external power limiter.
An integrated digital power limiter can be set, using two external bits, to deliver a specific output (10 W, 12 W, 15 W, or 20 W).
The LM49251's ALC feature provides designers with a programmable output power limiter for speaker protection and clip level select.
Features of the TCS and TCE are said to include a self-turning PID algorithm, an intuitive color display with text messaging, universal process and TC/RTD inputs, a multifunction ramp-dwell/process timer, a soft start output power limiter, up to four control and alarm outputs, a load current display and fault monitor, and much more.

A family of four new optical protection products includes the Optical Fuse, Optical Power Limiter, Optical Network Protector and High Power Optical Terminator These devices protect components and equipment from over-power conditions that are common in networks where optical amplifiers and high power sources are present.
However, such high-performance superconducting components are vulnerable to damage if exposed to high-power transient signals, such as lightening strikes or unintentional radar illumination and thus need to be protected by an input microwave power limiter. Conventional power limiters would increase the insertion loss or significantly reduce the dynamic range of the system, thereby compromising the advantages of using superconducting components.
Product manager Paul Beasly commented The high power limiter is designed to provide a complete solution for the most demanding applications in the smallest possible size.
Available in die format, the HMC913 features power limiter circuitry at its RF input and carries a class 1A ESD rating (250 V HBM).
The dilemma facing the manufacturer is whether to design in more expensive output circuits that can cope with double the power or to limit the output power by using a relatively low-cost power limiter. In fact, it is possible that the use of a limiter in MOSFET power amplifiers is the origin of the term linear at 3-dB compression.
This unit exhibits a typical noise figure of 2.5 dB and incorporates a high power limiter in the front end of the amplifier.
