DC-DC Converters

Im looking for a 12V to 24V DC-DC converter for my RD30

Anyone used one before? Are they ok?

something like this http://www.snaptec.com.au/dcdc/pdf/GB2-120-Series-dcdc-converters.pdf

I think FuFuFuFuFuFuFuFu has a 12V to 24V stepper that can supply about 55W and runs off a molex connector.

PS: Since I can't remember is there's more than one FuFuFuFuFuFuFuFu, it's the manufacturer that used to make aluminium radiators.

startup current on an rd30 is 10A ( so 240W at 24V )


the orion 12/24-10 looks like the ticket

Shit, sorry I did not know about that. Not meaning to be a bother, but do you know of any sorts of graphs out there that show a current time trend, because that seems absurdly high.

It'll work, but it's ~135USD+. Why not just get a Meanwell to run off your mains, for about half that price (http://www.jameco.com/webapp/wcs/stores/servlet/ProductDisplay?langId=-1&storeId=10001&catalogId=10001&pa=137657&productId=137657&keyCode=WSF&CID=GMC)? Efficiencies are about the same either way.

The GB2-120 series DC/DC converter is a highly integrated DC/DC
converter designed for DC/DC conversion. This series is rated at 120W.

only supports 5 amps @ 24v GB2-120-1224 with 12v input and 24v ouput

are you set on using DC/DC converter or will do AC/DC converter?

for most dc/dc converters are low powered with 12v input

Orion 12/24-10: + 0% / - 5%) 1.2v ripple mite need filtering for clean power

im gona give this little sucker a try

the manual says the RD30 runs at 3.2A and has a 10A starting current

hopefully this will hold out

replace 680uF cap with diode one 1 term(polarity observerd) and larger surge cap (http://www.wiltronics.com.au/catalogue/169108/electronic-components-and-parts/capacitors/electrolytic-capacitors-hi-capacitance-10-000uf) PDF (http://www.wiltronics.com.au/datasheets/kendeil.pdf.pdf)

it will give that extra kick when motor starts

mite be a issue with "Soft-start function reduces in-rush current during start-up" depends on how much of a cut
