I am trying to find links to purchase these items. The black box is a DC to AC inverter 11-15 VDC input 115 VAC output. The smaller red card is a DC to DC boost converter 10-32 VDC input 12-35 VDC output. And the two other pictures are the front and back side of a led digial voltmeter that need Voltage sensing 30-500 VAC. Could you guys help me out with finding these?
For the inverter, we don’t seem to have a direct match in stock, just based on the input and output voltages alone.
As for the DC/DC converter do you have a power specification, or max current output for it? And are there any distinctive markings on the voltmeter? It looks like the text is cut off in these photos.
I didn’t inculde this ealier but I am building out a tester using these componets from a parts list and these are the partnumbers that were provided to me. I hope this helps out with searching. It didn’t for me.
DC/DC converter PN:OSKJ DC-DC boost converter
DC to AC inverter: 243-1737
Voltmeter: 1AA800076-R
The inverter doesn’t have to be the exact model just smiliar inputs and outputs. For the DC/DC converter 10Amps is fine for max current output. I don’t unfortunatley have any marking for the voltmeters. But I know the digital numbers are displayed in red.
Hi kenneth.hillen,
I’m a little fuzzy on a few things.
Primarily, what’s the purpose of having a DC-DC converter with a minimum input of 10 Vdc if it’s feeding an inverter which can take as little as 11 Vdc? Do you expect that your source voltage will always be at least 10V but may be less than 11V?
I would note that I can find those part numbers online elsewhere. They seem a little sketchy to me. We do not carry those specific parts. Below I link to some other parts which you might consider as alternatives.
Again, I’m not offering any DC-DC options unless you have a really good reason to require it. On the surface, it seems like it would just be a waste of power.
Regarding your inverter, here’s a link to some options.
For the voltmeters, here are some options, as long as your intended output will be less than 300Vac.

Here are the energize scematics for the relay tester and the pin out scematic to the voltmeters from the relays. I have never made these scematics before and am just trying to make more from prototype and scematics. it llooks like the dc ac inverter is used for only K4 relay if that helps answer your question.
Do you have any information about the relay in K4? It may be easier, not to mention much cheaper and more efficient, to use a different relay rather than using an inverter.
