Another issue with unregulated supplies is that the output voltage not only is a function of the input voltage, but will also fluctuate with how much current is being drawn from and airplanes were in Reply With Quote 09-30-2006,08:19 PM #14 hankpajari View Profile View Forum Posts Private Message Join Date May 2003 Location Granite Bay, CA Posts 462 Gallery My Gallery look at this site
This permits continuous transition from constant current to constant voltage modes in response to the load change. You need to get into the 750's to see that many amps.In basic language can anyone tell meA. Voltage times current = watts. How do I measure ripple and noise?
Do all waves of any kind satisfy the principle of superposition? Constant Voltage Supply A slightly more complex power supply than the battery eliminator supplies a constant, adjustable voltage. Do all waves of any kind satisfy the principle of superposition? Power Supply Amperage Calculator You have, of course, to make sure that the voltage, amps and connector size are compatible.
This is the crossover point where the power supply goes into the constant voltage mode. Power Supply Amperage Too Low This can be done with an oscilloscope or a wideband AC RMS voltmeter. Because it has attracted low-quality or spam answers that had to be removed, posting an answer now requires 10 reputation on this site (the association bonus does not count). http://www.tomshardware.com/answers/id-2661316/power-supply-amps-question.html Question; Why is a 750 watt PSU with 50 amps better than a 550 watt with 69 amps.
Can't find your answer ? Computer Power Supply Amps Olin explained with fruit, I'll try to explain with another flow: water. I know it lists three +12 volts rails. The channel 1 and channel 2 outputs are 31 volts at 3.1 amps and the third channel will output 6 volts at 3.1 amps.

Can I Use A Power Supply With Higher Amps Hot Network Questions Why does Smith keep asking the duration of employment to his staff members Disarium Dilemma If Russia hacked the election, how or why can we proceed with inaugurating Can I Use A 12v Power Supply On A 9v Is there any advantage in stacking multiple images vs a single long exposure?
When the overheating problem happened, I had the triton as well as an ace super smart charger hooked up to the power supply. this page I have learned a lot but am still confused about PSU watts and Amps. The power supply's isolation between input and output or chassis comes from the isolation provided by the supply's transformer. Related Resources solved PSU, Watts, Amps, and Graphics card question! Power Supply Amperage Too High
The power waveform can be gotten by multiplying the current and voltage waveform using the oscilloscope. The transistor is usually a bipolar or MOSFET type (sometimes as part of a control IC for smaller supplies) and is operated in its linear region (hence the name, "linear" regulation). What are your specs? http://wphomeguide.com/power-supply/power-supply-fan-question.php A key fact is that the switching element (a transistor) is either off or fully on (saturated).
This isn't surprising, as controlled electrical energy is used in a tremendous number of ways. Power Supply Current Rating Can you figure out how we're related? Voltage/Watts/Amps?
Is it legal to use handheld radios to listen to aviation frequencies in the USA? When current reaches the limit, a typical CV/CC power supply will switch from CV to CC mode. See the Output section under Power Supply Specifications. Can I Use A 12v Adapter For 6v Why is there such a large variation in prices between power supplies?
The PS may get used for other applications other than RC hobby stuff... Initially, the open circuit voltage of the power supply may be preset for 13.8 volts. A rating of "0%" would mean perfect regulation.Load regulationHow much the load voltage or current changes between operating the power supply at no-load and full-load conditions. useful reference Higher capacity batteries take longer to charge, and a beefier power supply can supply more current to the battery to charge it faster.
Basic transformer unregulated supplies fed from 60 Hz AC will generally ripple at 120 Hz, for example. If it's completely different (different voltage for instance) you could do damage to both. –Chris S Oct 25 '10 at 14:56 If the supply can't provide enough power, it Reply With Quote 04-07-2010,02:44 PM #19 Rodney View Profile View Forum Posts Private Message Join Date Dec 2001 Location FL Posts 7,666 Gallery My Gallery Models My Models Ratings My Feedback In addition to supplying constant voltage, these supplies can also supply constant current.
All in favor of making this the canonical "consumer electronics power supply question" vote +1! –W5VO♦ Jun 28 '12 at 23:05 4 Not sure. This is rarely specified and would probably have to be measured.

On several electronics sites I see enthousiasts like us overwhelming visitors with so much information and details, so much that they leave and probably never dare to return. Watts? Multi range supplies are different in that they recalculate voltage/current limits for each setting, forming a constant power hyperbolic shaped boundary as illustrated in the diagram below. This means the set of instructions sent to the instrument over the digital interface and the information received by the computer from the instrument.
This is a practical and useful tool for the troubleshooting bench. 1 These variable transformers are often called "Variacs", which originally was a trademark of General Radio Corporation, but the word In that sense, unlike with voltage, the current rating of a power supply must be at least what the device wants but there is no harm in it being higher. Can I connect in parallel? display brightness + using an external display.
It happens occasionally; though for the most part you're right. –Chris S Oct 25 '10 at 14:58 add a comment| up vote 0 down vote The power supply can provide electricity Click Here to Log In Forum Radios, Batteries, Clubhouse and more Batteries & Chargers Triton power supply question, how many amps? Used to describe an unchanging voltage, current, or electrical power.DriftThe change in time of an output voltage or current.Electronic loadA type of instrument that serves as a load, usually dynamic, and Some models may not be adjustable all the way down to zero volts and their maximum output current may be proportional to the output voltage, rather than supplying the rated current
A device that is trying to draw the excessive current probably won't function correctly, but everything should stay safe, not catch fire, and recover nicely once the excessive load is removed. Does runway 32/33R at Madrid actually have a kink in it?
