Has anyone put a (calibrated) frequency monitor on this generator? My current generator (not this model) runs @ 63 HZ @ low load, which causes issues with my UPS's. I've seen similar comments on many others. I believe they overspeed them intentionally...

It should have a governor adjustment screw. My 5500 watt version of this generator does, and after adjusting it, I got it to run at 3600 RPM exactly, which translates into 59.9 to 60.1 Hz ALL THE TIME, with ANY normal load. Here's where the screw is: imageupper.com/i/?S0200010100011I13896654381023200 To see the frequency, get a meter that measures frequency, such as a kill-a-watt power consumption meter.

I have one on a P2770FH that is not working very well. My OEM is rated at 14VDC and 3.5 amps. This power supply is rated for 3amps and my monitor turns off after less than an hour of use. I have to wait for a little while and then I can turn it on again. It maybe my monitor and not the power supply. I am going to order another power supply with higher amp rating and see if it will stay on.

Please, people. He's asking how long it would last at full load. It's a pretty common question for UPSs and when it's asked, it means FULL LOAD. Answer his darn question. WILL THIS UPS LAST FOR AT LEAST 30 MINUTES AT FULL LOAD? HOW MUCH LONGER?

I seriously doubt you are using anywhere near your power supplies rated maximum. I have a 1000 watt PS connect to this UPS. Normally, it draws less then 300 watts. Even gaming, I've rarely seen it over 500.

Mine kept burning up the rectifier . I went through 3 rectifiers before I decided to take it apart to look into the problem....cheap wiring .I recommend Missouri wind and solar.their staff will help you find the wind generator to meet your needs .I used mine to charge my battery bank. what I run I do it with my 2500 watt pure sine inverter.I'm totally off grid .

iconnected mine up and tried to figure the minimum speed I really did not have mine operable long enough to figure out a minimum speed the generator only worked for a couple of weeks then stopped generating!! this was some time ago but as i recall it took some pedaling effort to get the light bright enough to be usable.. certainly not a very low or relaxed pedaling effort.

The previous answer is actually incorrect based on my original research. Electronics (especially sensitive ones like computers, televisions, etc) are sensitive to "clean power" vs. "dirty power". Generators usually produce a rough signal, not a nice sine wave like you would get from your normal home feed. The spikes, both low and high, can damage or adversely affect your electronics. You definitely do not want to risk a direct connection. Personally, I've used the generator for the basics (heat, fridge, etc) and not for electronics. If you DO want to use it for other sensitive items, the suggestions I saw were that you pickup at least a UPS, and/or a Automatic Voltage Regulator. I don't have much experience with the AVR, but a UPS is a useful item to have either way if you can afford one. My advice is to do a little extra research on Google, you'll likely find others have asked/answered the question in detail. Good luck!

Interesting Question... In the USA power is supposed to be 60 Hz and 110 to 125 VRMS. The voltage can vary in this range due to loading, but it's generally pretty stable around 120 VRMS (your own results may vary). Now the frequency is a different matter. In the USA the frequency is pretty stable. I doubt it's as low as 59.9 Hz or as high as 60.1 (this stability is not the case in some other countries). Now a generator is governed to run at 3600 RPM (60 Hz) but the stability is not that great. I wouldn't be surprised to see +/- 2 Hz (4 Hz range). Many appliances won't care and run fine. But there will likely be some that are finnikie. Old analog clocks actually kept time with respect to this frequency (You'd be hard pressed to find one today). Some TVs may be designed to use the 60Hz line frequency for the frame rate signal. I don't think todays flat screens use this, but maybe... I just haven't looked into it. Bottom line is that when running off a generator, your line frequency will not be as stable. It could be a problem on some appliances. Still, Most things will run just fine. I've run my house off my generator and everything worked just fine. I did have an old TV (2004 vintage) that complained about the frequency being out of range. I just ignored it. It seemed to work most of the time, (but not always) but It didn't seem to damage anything. When I went back to grid power, everything work again without any problems.

50 Hz Is a little low. If you are running a generator, I would dial it up to 55 Hz if possible. Running that low of current might burn the motor up because it won't be enough power to turn it.

Honestly I'm mot sure. I did take apart the switch unit to see if there were posts to change the frequency. When I opened it I noticed the main board was a very cheaply made one materials wise. I would wager the seller intends low amp and voltage for the unit. Im not an electrician but I do know computers. Im basing my guess on personal observations.

When I received it and with a 1500 Watt load, mine was running about 62.0 Hz to 62.2 Hz at 122.5 VAC. There is a governor adjustment (a phillips head screw) located on the motor just above the recoil start housing. It's easily accessible from the same end where the choke control is located. I was able to adjust it so it is almost exactly 60 Hz, +/- about 0.1 Hz. The frequency being off is probably the largest problem when dealing with twitchy furnaces (mostly the variable-speed ones) and computer UPS systems, so this is a worthwhile adjustment to make.

Hmm That does sound like a serious issue! I cannot say that I have had that problem yet and I have 8 units installed in my house. It sounds to me like the unit is placed on a circuit that is beyond the recommended load which can easily happen. In other words, this issue sounds like people are using the units on circuits that were already poorly wired. Just my thoughts.

Yes this generator supplies safe and constant voltage at 120 volts/ 60 hz for any electronics. Remember to never start or shutdown your generator with any electronics turned on or any other load on your generator!

It's a best practice not to use the LC1200 as well as any of the other line conditioners in our offering with a generator. We do however have true online UPS systems in our offering that are considered generator friendly. For assistance in sizing out a UPS system to use in conjunction with your generator, please reach out to our presales applications team at 773-869-1773 or via email at presaleshelp@tripplite.com.

It only shows runtime, load capacity and voltage. For watts you should look into a kill-a-watt device like this one: http://www.amazon.com/P3-P4400-Electricity-Usage-Monitor/dp/B00009MDBU I have one of those and it works great. Plug it in before the unit, then plug the unit into it and you will have the watt display of the whole ups.

Generally yes but it depends on the quality of the output of the generator. The UPS will sense the frequency and voltage of the generator's output. If the output of the generator falls outside the allowable parameters, the UPS will kick in a take over the load. If that happens too often, the UPS's batteries will be depleted and the UPS will shut down until they are recharged.
