Performs above 40 ☌įorced cooling by fan operation of the pulley provides a lot of power in higher temperatures, especially close to the engine. The 12/130 and 24/75 models are also available with a multigroove pulley. The Mastervolt Alpha alternator is specifically designed for powerful charging, even with a low engine rpm. Hence 24 volt alternators are a great solution to any electronic supply that has a low. More commonly known as a voltage sensitive (or. 2) Fit a 24V regulator and run at the same speed, will work, but not efficiently. Run it at twice the speed (assuming it doesn't exceed the rev limit and disintegrate). Standard alternators only supply the specified capacity at a high rpm. 24 voltage alternators are a great solution to any electronic project. The 12v / 24v 120A Cyrix CT battery combiner from Victron Energy is a feature-packed intelligent split charge solution for charging your leisure battery from your alternator and ensuring you never accidentally flatten your starter battery. Re: can you make a 12v alternator into a 24v alternator. Some engine brands come with Mastervolt alternator brackets as an option. For all engine typesĪlpha alternators are equipped with several fixations for customised alternator brackets, available from your installer or engine supplier. TIP: A second alternator on the main engine, combined with a larger battery bank and inverter, could be an alternative for a generator. There are many different regulators available through a rebuilder depending on the type of alternator you use. As a global leader in high-tech, high-quality rotating electric products, Prestolite Electric carefully engineers and extensively tests its alternators to maximize performance in even the harshest use. To go with that, you need a 24 V voltage regulator. The Prestolite and Leece-Neville product line includes high-output, high-performance alternators for virtually every vehicle and equipment class. Using a Battery Mate or battery isolator in conjunction with an Alpha alternator makes it possible to easily charge two or three separate battery sets simultaneously. The rotor in a 24 Volt alternator will be wound differently than a 12 V rotor and therefore needs to be done properly. Standard delivered with Alpha Pro MB charge regulator for an optimal performance and longer-lasting batteries.Fast & complete charging of starter and service batteries. Performance Output, 12 Volts 430 Amps 24 Volts 250 & 275 Amps Maximum Speed, 8,000 RPM Continuous 9,000 RPM Intermittent Rotation, Clockwise Temperature.The invention allows the use of one alternator/engine combination to charge either a 12 volt or 24 volt. A 12-24 volt alternator regulator charges a 12 volt battery or a 24 volt battery depending on the position of a mode switch. Not the 1.5 5 volts I thought the PCM provided. Abstract: A dual state power system utilizing power drivers to switch an alternator from 12 volt to 24 volt charging. The battery is new and the small red wire to the alternator reads switched 12v battery voltage. Is the exciter circuitry independent of and unrelated to the voltage regulator?Īnyway, I look forward to returning to Aletes in a few weeks to pursue this and would like to be as knowledgeable as possible if you have any thoughts. the 100amp Alternator quit charging, tried a new 220amp it won’t charge either. forumda ve internette yaptm aratrmalar sonucu ba evi için güne paneli sistemi kurmaya karar verdim.Is the control logic for this fault light any more complicated than that? This probably indicates that the 24v alternator was not yet producing 24v. I have noticed that the alternator fault light on the 24v panel historically stayed on after starting the engine while at low rpm, but generally went out after a small increase in throttle.Is it the case that the 24 alternator would be “self-exciting” after generating 24v? If so, is that “self-exciting” dependent on rpm? And if so would this relay drop out the external 12v power for the exciter? Manufacturer of DC Power Alternator - DC Charging Alternator 12V/24V, D.C.Since the 24v alternator is not producing 24v at startup, is the 24v alternator exciter circuit initially powered by the 12v battery (simultaneous with the 12v alternator), or by the 12v alternator after it is producing its 13.5v? There could be a design theory that the 24v alternator is excited by and only AFTER the 12v alternator is producing 13+ volts thereby reducing startup load slightly.Any insights you have on the following would be helpful. The internet is not providing much relative to exciter theory or engines with both 12v and 24v systems. I cannot find any circuit diagrams for this and I am not at the boat to trace the circuitry. I am still trying to understand the circuit logic for the exciter. I have not yet tracked the behavior of the fault light on the 24v panel in these various conditions. Then backing down rpm continue with 24v output until about 1200 rpm, and below that not. Operationally at this point, at startup we are not getting 24v alternator output until about 2000-2200 rpm.
