To test another scenario, you can set the output to 20mA, attach a small LED to the output – and turn the unit on. In this case the output voltage stays rock solid at 5v and the supply itself remains cold enough. When the current limit is removed, the same load draws 2.4A and that’s a total of 12w of power, which follows Ohms Law. When the maximum current is set to 1A, voltage is set to 5V and connect a 2-ohm load, the voltage immediately drops to ensure no more than 1A flows through the load. Once the software is loaded, and the serial connector is connected to the board and PC, you are able to control the board from the onscreen menus. You can use the available software to make a serial connection (wired or wireless) to the module, by downloading the PC software accordingly. UART to USB converter and a Bluetooth module (with pass: 1234, which just looks like a wireless UART COM port). In the box, there’s is also a FTDI – i.e. DPS5020 Unboxing USB and Bluetooth Connection Along with the package, you will receive a small user manual, cables, and the two main modules. Using the provided instructions, assembling and switching on the device is straight forward. In comparison with traditional analog power supplies, it is more convenient to quickly set the voltage or current required. You can also quickly set two stored group values. The DPS5020 can store up to 10 preset group values which are preserved during power off. The front panel module has buttons and a control knob to set the desired voltage/current and an OLED display to show actual readings and set points. The main board has connections for input/output voltage as well as connection headers for Bluetooth and USB to Serial converter. Th e module is a 0-50V/0-20A Lab PSU module that comes in 2 parts, the main controller and a front panel. The DPS5020 is a constant voltage/current programmable control power supply module, that integrates analog and digital control in one device.
