Feb 19, 2006 · Now a days, those computer supplies are very cheap. I was thinking if is possible to modify to 35 Volts for instance. Do you think that the oscilating frequency will be captured by
Mar 13, 2015 · I am about to build an OUTDOOR antenna amplifier. The amplifier will be screwed to the OUTDOOR antenna, but its power supply will be located INSIDE the house next to TV
Mar 23, 2005 · Portable power supply for amps or PA. There are times, especially when playing outdoor, when there is no AC power available. For those times it would be nice to have a
There are times, especially when playing outdoor, when there is no AC power available. For those times it would be nice to have a battery powered amp, or a DC to AC converter you can connect to a 12 volt battery. Battery powered amps seem to always have very low wattage output, with small speakers and don't sound very good.
TNT-Audio has a very good article on amp power supply that describes various designs. IT explains the purpose of RC network and small value caps as well as purpose of dual rectifiers. The diagram you show correspond to fig 4/diagram 4 in the article.
So ultimately, the primary characteristic needed is stability, all things considered, the power supply should have no effect on the amplified audio by way of fluctuations in DC potential available to the amplifier circuitry. Practical power supplies for HiFi amplifiers could be linear, switch mode or (less practically) batteries.
And all good amplifier designs run all low-current circuits from low power regulated supply lines, where a regulator removes all noise down to a noise level comparable to a battery. Generally, switch-mode supplies are much smaller, they often have reduced output for low frequency loads, and they require more knowledge to design.
Tube amps run very high voltage internally with current levels in the ‘no return zone’ meaning, getting zapped while playing in the outdoors could be that final gig.” (These days I only use solid-state amps through these things which is much safer overall, tube amps also drain the batteries very fast in comparison.
Audio, Audio, Audio! In any well designed HiFi amplifier, there will be a power supply whose job is to convert the AC mains supply voltage to a DC voltage. The power supply must also be able to provide a reserve of power to cope with any sharp transients in current demand without suffering a decrease in voltage output.
The global industrial and commercial energy storage market is experiencing explosive growth, with demand increasing by over 250% in the past two years. Containerized energy storage solutions now account for approximately 45% of all new commercial and industrial storage deployments worldwide. North America leads with 42% market share, driven by corporate sustainability initiatives and tax incentives that reduce total project costs by 18-28%. Europe follows closely with 35% market share, where standardized industrial storage designs have cut installation timelines by 65% compared to traditional built-in-place systems. Asia-Pacific represents the fastest-growing region at 50% CAGR, with manufacturing scale reducing system prices by 20% annually. Emerging markets in Africa and Latin America are adopting industrial storage solutions for peak shaving and backup power, with typical payback periods of 2-4 years. Major commercial projects now deploy clusters of 15+ systems creating storage networks with 80+MWh capacity at costs below $270/kWh for large-scale industrial applications.
Technological advancements are dramatically improving industrial energy storage performance while reducing costs. Next-generation battery management systems maintain optimal operating conditions with 45% less energy consumption, extending battery lifespan to 20+ years. Standardized plug-and-play designs have reduced installation costs from $85/kWh to $40/kWh since 2023.
