Summary of RUIDENG DPS5020 – 50V 20A POWER SUPPLY MODULE REVIEW
The DPS5020 is a 0-50V/0-20A programmable power supply module integrating analog and digital controls. It features a main controller board with Bluetooth and USB headers, paired with a front panel containing buttons, a knob, and an OLED display. The device supports ten stored presets and includes current limiting capabilities for safe load management.
Parts used in the DPS5020 Project:
- Main controller board
- Front panel module
- OLED display
- Control buttons
- Control knob
- FTDI UART to USB converter
- Bluetooth module
- User manual
- Cables
The DPS5020 is a constant voltage/current programmable control power supply module, that integrates analog and digital control in one device. 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 main board has connections for input/output voltage as well as connection headers for Bluetooth and USB to Serial converter.
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 DPS5020 can store up to 10 preset group values which are preserved during power off. You can also quickly set two stored group values. In comparison with traditional analog power supplies, it is more convenient to quickly set the voltage or current required. Using the provided instructions, assembling and switching on the device is straight forward. Along with the package, you will receive a small user manual, cables, and the two main modules.
USB And Bluetooth Connection
In the box, there’s is also a FTDI – i.e. UART to USB converter and a Bluetooth module (with pass: 1234, which just looks like a wireless UART COM port). You can use the available software to make a serial connection (wired or wireless) to the module, by downloading the PC software accordingly. 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. 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. This is the current limiting feature.
