2024年9月18日 · I have a small engine driven generator that I am trying to build an AVR for. It is an 1800 RPM alternator with two slip-rings, 5 KW, 120/240 volt single phase unit driven by a 4 cylinder engine. This unit was built in the fifties and everything checks out but it is missing the voltage regulator...

2015年10月8日 · Hi guys Does any one know how a generator AVR (Automatic Voltage Regulator) bench tester works ?. I am planing to build one to test AVR's instead of having to connect them to a generator each time i want to test one. Thanks in advance.

2024年6月1日 · I think you are right that the generator has two field windings. A-B supply for avr is probably also used for voltage measurement. Mystery terminals I guess are used for starting magnetization. I made a drawing, does that make sense?

2009年1月14日 · This generator is equipped with an automatic voltage regulator (avr) that is physically damaged. This particular avr uses the input of 120vac from the stator and apparently rectifies it for use as an output to the brushes to control rotor …

2015年12月27日 · I'm quite a beginner in embedded systems. I was trying to create a simple system that consists of two ATMega32 micro controllers. One of them stores a value in an EEPROM and the others reads it from the EEPROM and lights a led depending on this value. I've done the writing part successfully...

2011年6月19日 · I believe you are approaching this problem incorrectly, if I understand the problem. To measure current, use the smallest value resistor in series with your circuit, a value that will give you reasonable voltage that you can measure. You know the value of the resistor, measure the voltage across the resistor with the micro …

2018年12月22日 · My AVR just knocked off. There is no output voltage being supplied but there is input voltage. I desoldered the relays, tested them with a 9v battery though rated 12v they energized. There is no physical damage of components. Please how can I repair it?

2009年1月14日 · Thanks nagaloo and ifixit for all the great effort. I'm attempting to link to a schematic of the Honda generator as I thought it might add some insight on possible inputs to the AVR. I noticed specifically how they tap the stator at a different point apparently limiting the input voltage to the AVR.

2018年1月27日 · Given a choice I would get the AVR (Automatic Voltage Regulator) system. For years I supported our home with a small 4 KW (5 KW surge) generator during power outages before moving to a much larger auto start and transfer system.

2024年12月26日 · I have this board: FT232RL -usb-to-TTL or serial-uart-module - pinout. From what I read, TTL and UART is the same thing? or at least very close in functionality? I originally bought it as a usb to TTL. The FT232RL IC datasheet. --- [ -I want to use my C# to command a number of In/Out pins]--- Im thinking maybe this module can bridge between my C# and some multi-IO port IC? First of all ,-if is ...
