That's a lot of regulators and heat sinks. Full current specs of regulators include that they are heatsinked. Many manufactors have schematics of regulators useing series pass transistors to increase the regulators current capacity. less space less heatsinks and it will work correctly. joe

I don't think u can, The inrush is so high that the DC to Ac inverter stalls and won't start. Some short time fix could be the tempture of where u are operating the inverter cold temps will cause your problem and too small of wire size on the DC input side of the inverter. Had this same problem with...

How about the type of exhaust cap found on large trucks. Metal counter weighted flap valves good model to start with maybe.

Like AutoCad or Orcad different elements in a drawing are on different layers and are different colors. for P.C. layout they could be traces on the top side and a different color for the back side, or power supply lines positive and negitive ect,ect. Where they intersect could be a via where the con...

Some use magnetic seperators for this problem,or vibration or size weight differences.. the plastic parts fall on to a screen which they can not pass through but the metal will some times aided by vibrating the screen or the container that the material stream falls into ... or strong pm magnets that...

design of even a small wattage inverter is not easy. Things u have to consider is transfer power,transformer loss, counter emf of transformer fields effect on switching transistors, bootstrap starting (inverter stall on start up only one side turns on and the other off in a static condition) If u ar...

not a simple as it sounds 12 volts d.c. to 120/240 a.c. is very poor conversion ratio for any high current designs. d.c. curent in is the same as current out a.c. less losses. 135 volt d.c. would be smaller for high current large inverters bigger than 5 or 600 watts use PWM control and IGBT transist...

diodes will drop the charge voltage by 1 volt 10.3 volts D.C. is a dead battery discharging any lower damages the battery float charge on a sealed lead acid battery is 13.6 volts nominal is 12.6 solar cells must prduce enough current to apply a higher voltage than the the open jar voltage 12.6 batte...

what it sounds like you have a dancer contoller board which takes a 1-5 0-10 volts input from a variable reluctance transducer ( detects arm position on take-up reel in winding operation ..tape ,duct ,wire ,ect controls take-up speed as the build on the spool drum increases in size slows down the re...

the smaller cable only has have the current flow in it thus smaller cable to the other battery the larger wire carries all the current for the starter 700 amps

crowbar you got it right.....but u can measure across the fuse while current is flowing through it this voltage drop times known current through fuse will tell you the loss in watts of the connections in this parallel arrangement and how balanced the current flow is and this number will probably var...

you are not shorting out the battery in that case.. the short resistance would need to be lower than the internal resistance of the battery...which can be .0003 ohms or there abouts it is very low.<p> joe

if u use a inverter or a ups .. which is a batery charger + inverter + a switch to connect the load to the inverter or to the main power lines. the in rush will require at least 10 times load for the inverter to supply..inverters at low voltages on the dc side need lots of amps ( load = 20 amps tota...

if u can find a neutral, 277 volts is doable. but to find the ratio u want may be hard to find..maybe using a regular trans former as auto former if u don't need isolation or can obtain isolation in a different section of the circuit u are going to use we use a multi tap xformer to get feedback for ...

some transducer manufactures can give u different outputs ex 0-30 mv 0-5 volts 0-10 volts and current loop 0-20 ma. their are several manuf of amp modules that allow u to get what ever output swing in a window of hi lo voltages. one trick i know of is that most transducer outputs are not always zero...
