Application:

For Datakom Generator Alternator

Notice:


Introduction:AVR-20 Voltage Regulator is an electronic device that allows the alternator to produce fixed output voltage. It has open chassis, molded resin design and is intended to be mounted on the alternator terminal box.
AVR-20 measures the voltage between one of the alternator phases and the neutral point and adjusts the DC voltage applied to the excitation winding until the desired voltage level is reached. The output stage of the output device is a half wave tyhristor associated with a freewheeling diode. basically the unit is compatible with all brushless type alternators. a stability adjustment pot is also provided for this purpose. the AVR-20 relay has a special-less electronic circuit design. the minimum residual voltage required to build is 5 V-AC.
the unit does not include moving parts; so it is capable of operating in highly vibrating environments. the AVR-20 includes a low frequency protection circuit. this feature reduces the output voltage during motor overload or shutdown. therefore, the diesel engine is protected from excessive torque currents generated by the high start of large electrical equipment. likewise, the diesel engine can be stopped under load without damage. the device connection scheme allows for quick and easy replacement.
FEATURES:half-wave thyristor output,0-20 amps. the output current,0-115 volts output voltage,relay-less circuit design,low frequency protection,built in tension adjustment,remote voltage adjustment,stability adjustment,easy connection scheme,compatible with various types of alternators.AVR-20 Voltage Regulator is an electronic device that allows the alternator to produce fixed output voltage. It has open chassis, molded resin design and is intended to be mounted on the alternator terminal box. basically the unit is compatible with all brushless type alternators. a stability adjustment pot is also provided for this purpose.the AVR-20 relay has a special-less electronic circuit design. the minimum residual voltage required to build is 5 VAC.
OPERATION:the device operates at 230-volt phase-to-neutral voltage. the output voltage, as well as the internal voltage supply, is directly picked up from the voltage detection input. the device needs 5 V-AC for startup. the half wave tyhristor maximum output voltage is 115 volts. during operation, the device continuously monitors the input voltage and increases / decreases the voltage excitation in order to keep the input voltage to a constant value.
the AVR-20 keeps the alternator voltage change to a minimum in the event of a load change, and helps you reach the required voltage value quickly. the regulation is the PI type, the proportional reaction member is fast and the slow action helps the reaction unit to recover the precise set of voltage. the potentiometer stability adjusts the reaction speed of the device. this helps the unit to comply with a wide variety of alternators.
the AVR-20 is capable of producing up to 20 amps of direct current output. The alternator voltage can be adjusted through the built in potentiometer. also external voltage adjustment feature is provided, in this case the value must be 1 kilo-ohms external potentiometer. the low frequency protection circuit switches off the excitation voltage to prevent damage during the engine stop under load. the factory set protection value is 45Hz.the terminals must not be connected to any alternator EXCITATION point but the unit. the NEUTRAL and EXCITATION (+) points are connected internally.
INPUTS AND OUTPUTS:PHASE-R: Input phase alternator.NEUTRAL: Neutral input alternator, internally connected to the Terminal Excitation (+).EXCITATION (+): Excitation winding (+) of the terminal, internally connected to the Neutral terminal.EXCITATION (-): Excitation winding (-) terminal

Didn't Know What I Was Missing All This Time
I saw a random video about "safe cut"(or "safety") can openers and comparing them to the traditional can openers that are more known and popular. I was skeptical because it made no sense why something that performed like that wouldn't be the known and popular style of can opener. But I was intrigued enough to try one out and was very happy to see a AmazonBasics option. AmazonBasics proves to be worth the savings more often than not compared to their counterparts. I was happy to take a roll on it. The video was no gimmick, these things are amazing. No more lining up wheels, grip crushing levers, and clunky grinding cranking. No more sharp edges or lids falling into what you want to eat. The clean cut is amazing. Put it in place and start spinning, it grabs and does the job. The lid doesn't fall in. And there's no sharp edges. It's baffling that these aren't the "known" can opener. These are what you should think of when somebody says can opener, not the ones you do. This AmazonBasics Safe Cut Can Opener is built well and I expect it to last for many, many years. MAYBE it can't tackle every can. But I've yet to run into one I can't open with it. Couple that with the ever growing prevalence of manual pull tab cans and my traditional can opener hasn't been touched since I got this a year ago. And hopefully never will. I'm a convert. Safe cut is the right cut!

doesn't open can, leaves aluminum shavings
could not cut through rim of can at all, it barely even grabbed on even after trying on multiple cans. Just spun almost in place and left small aluminum shavings and slivers from the can on the counter. the mechanism does not compress and bit into the can enough to get through, just enough to tear it up

Excellent Can Opener – Safe, Effortless, and Smartly Designed!
I’m so impressed with this electric can opener! From the moment I took it out of the box, it was incredibly easy to use—just one touch and it does all the work for you. What really sets it apart is how it opens cans with a smooth edge, so there's absolutely no worry about scratching yourself or dealing with sharp, jagged lids. That’s a huge relief, especially for someone like me who cooks often and has had accidents with traditional openers in the past. The design is compact and sleek, making it easy to store in a drawer, and it feels solid and well-made in the hand. It’s also surprisingly quiet while running. I’ve used it on all types of cans, and it works like a charm every time. Honestly, I didn’t expect to love a can opener this much, but it makes such a difference in the kitchen. If you're thinking about getting one, this is 100% worth it!
