MVP 2023 Flex727 Posted November 25, 2015 MVP 2023 Report Share Posted November 25, 2015 I'm sure everyone has a portable 24v power supply they use to power up Unitronics PLCs when out in the field. But how many times do you find yourself without a handy 110v power outlet? Wouldn't it be nice if you could power your PLC off the USB socket on your laptop, or even a USB battery? Here is what I put together: This steps up the 5v from USB to 24v for the PLC: DROK® LTC1871 3.5V-30V DC Boost Converter Power Transformer Voltage Regulator 5V/12V Step Up Volt Module Power Supply Board http://www.amazon.com/gp/product/B00DWX8PM2 This cable has a USB plug on one end and a barrel plug on the other: StarTech.com 2m USB to Type M Barrel Cable - USB to 5.5mm 5V DC Cable - USB to Barrel Jack 5V DC Plug http://www.amazon.com/gp/product/B009C3CJG4 These are to provide barrel plugs and jacks for connecting everything together with a bit of simple wiring: E-outstanding 5 Pair DC Power Jack (5 x Male and 5 x Female) 5.5mm x 2.1mm CCTV Power Jack Adapter http://www.amazon.com/gp/product/B011YKCK5M This box fits the boost converter nicely so everything is neat and tidy: Hammond 1591MBK Black Flame Retardant ABS Plastic Project Box http://www.amazon.com/gp/product/B003A67F90 A cheap 10,000 mAh rechargeable USB battery will run a V570 for about 4 hours. This is usually plenty of time for field work, but larger USB batteries are readily available and are not much more expensive. I'm using this one:Anker PowerCore+ 10050 http://www.amazon.com/gp/product/B013HSQXZC 1 Quote Link to comment Share on other sites More sharing options...
