        Thank you. There are two adjustments within the PS. Checking it the output is 13.5 v the charging is 13.5 v this maintains a trickle charge on the battery around 50 to 100 mA. I am using it on a police fire Ana EMS as well as monitoring local city Public works. During power outages I have no idea the status or time to repair. This works well for me.

    Could you guys please supply me with a data sheet for B071DQPRR5 that I purchased through amazon. I need to know if it has output protection. I am wondering if I need to install a diode to my DC motor. Thanks

      Hello Tanvir,
      We are terribly sorry we missed your message.Firstly, please allow us to apologize for that.
      This item(B071DQPRR5) has over load protection( 105%~200% of rated load), over voltage protection(115%~135% of rated output voltage) and short circuit protection. But it doesn’t have reversed protection.
      Hope this can help you.
      Best regards.

    Hello, I have one of your 480watt 0-48 volt power supplies with display, it says it can go to 10 amps at 48 volts. Which makes since 48 times 10 is 480. But is it still current limited at 12volts? Or if running at 12volts can I get 40 amps? I need to know before installing it as I do not want to hurt the supply.

      Hello Ian Vanderjagt,
      Thanks for writing in.
      It’s hard to confirm the item you mention. Would you please send the ASIN number or product link for confirmation?
      Best regards.

    I just purchased this 0-48 vdc power supply part #200218_EU. it was delivered today. I took the screws out to remove the top cover to get all of the plastic covering off of the aluminium case ans found one of the large capacitors rolling around inside of the unit. It wasn’t soldered to the board. it looks like the silicone that was used to hold it to the board had kept it off of the board enough to not get soldered in place. I soldered th capacitor back in place and everything seem to be working. Just wanted to let you know. I will also be posting this on the amazon review. I am letting you know first before I do. You really need to have better quality control. I shouldn’t have to solder pieces back onto the board of a brand new product. I really needed it, or I would have returned it. It appears to be working but I am concerned are there more solder joints that will fail.
