I assembled mine as per the directions from other purchasers. A DMM tells me I'm only getting 93V @ the blue wires and 3.4V @ the whites. What's wrong

You may have wired the primary coil for 240V. Check the AC power leads again. If you have 2 pairs of different colored primary AC wires try pairing one of each color for 120V AC connection.

If you have only two red wires then wrong transformer. If you connect both black wires to one side of 110 volt AC and both red wires to the other side 110 volt AC, if still 93V then something is broken. Either way, return item.

It sounds like you have the MAINS of the transformer series instead of parallel.. OR you have the 240V version by mistake?

I don`t know what is wrong... my starts in 390. Are you using the right voltage?

Hi and lo get the same voltage. Need to get the rectifiers for no light flicker. Mine work great!! Happy trails!

that is correct. if you connect them incorrectly nothing will happen. the voltage output will be one or two volts. if you connect them correctly you should get 18 volts. good luck.

Wish I could help. I had my electrician install. We had 220V running to the location of the low voltage Nest. They ended up working great. Prob should contact an electrician. It was above my head, and I'm a fairly knowledgable GC. Good luck. Jeff

I recommend you stick with same output V as the original equipment. I don't know what you are powering up, but some circuit board items might not be able to handle the added volts.

First of all I have never received my order from Amazon.I am still waiting. Secondly There will be a small voltage drop but unless you are using some very sensitive equipment it should not be a problem. I just hope Amazon comes through with my order soon. Art

This is probably too obvious and may not be helpful, but you need to adjust the current as well as the voltage. When I first started using this power supply, I had a similar concern, but found that adjusting current before voltage helped. Sorry if this is not helpful.

Sorry I have a different model fv-11vhl2 Only have black and white wires for each circuit, cant help

I had the same problem, I changed the battery (It's a CR2032 'button' battery.... available online for about 40 cents each) Once I put a fresh battery in it was fine. That was just a week ago, so I'll see how it goes. If it acts up again I will move the pins to channel 2 or 3 (less crowded area). Keep me posted, Don

My unit came through dual voltage and I can't see any difference when I'm welding except for max output being lower. I love my unit. Paul M

Make sure the blue plugs are together for cooling. Otherwise you might have to send in for a new plug

Do you want the relative voltage between D- and D+, or the voltage on each pin to ground? Either way, I only measured resistance between the data pins and not their voltage to determine that they were not shorted together like I needed. Otherwise I don't know the data pin voltages. My guess is a voltage bias between 0 and 5v or just 0.

That one stumped me too. Nothing in the instructions, although they do mention 12 VDC for that wire somewhere in a diagram. The instructions were horrible, and the thing never powered on. I returned it and got a refund. My suggestion is you do the same.

Make sure the wiring polarity is correct... I had mine reversed by accident at first, and it didn't work (plus the power wire almost immediately heated up).

I wanna say check wire diagram , look for wire labeled "park" (or similar). I will look into this issue for ya, if not resolved already.

Hi, sorry for the inconveniences. First please kindly confirm the working voltage is steady, secondly, the driver may not work properly. If you have any problem with your order, please kindly contact our customer service for replacement.
