      • 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.

  3. 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.

  4. 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.
