MDP-XP is A Modular DC Power Supply Kit For Your Next Project

My love for modular power supply design can not be denied. I find it cool, how you can increase the functionality of relative less powerful device just by adding another device on top or connected to it. With the explosion of the Arduino shields, the Raspberry Pi HaTs, I must say hardware modular design will surely be here for a long time.

MDP-XP Smart Digital Power Supply Kit

An interesting modular product discovered on SeeedStudio is the MDP-XP Smart Digital Power Supply Kit. This product is a new product carried by Seeedstudio as it can be seen on the front page, and it is an interesting product indeed.

The MDP-XP known as Mini Digital Power System is a system of programmable linear DC power supply inheriting the modular design concept where you can enhance the basic functionality of the device. It is a cost-effective DC power supply, featuring indicators, stability, reliability and distinct user interface comparable with professional power supplies

Its modular design allows it to connect different modules for use together depending on your application.

The MDP-XP is expected to come with the following modules:

  • MDP-M01 Display Control Module
  • MDP-P905 Digital Power Module
  • Digital Signal Generator Module
  • Electronic Load Module
  • Power Charger Module
  • Battery Pack Module

MDP-XP Smart Digital Power Supply Kit

Currently, only the Display Control Module and Digital Power Module is available for the supply kit, and the others are in development. Modularity interconnection is possible through a 2.4G wireless connection, capable of achieving multichannel free combination at the power of 90W per channel.

MDP-XP is capable of providing the following:

  • Programmable output
  • Timing output
  • Sequential Control
  • Automatic Compensation
  • and others.

The Display Control Module is equipped with a 2.8-inch TFT screen, making it look like a mini oscilloscope. It can display the voltage-current waveform in real-time, support data statistics, and automatically pair with and control six sub-modules (digital power modules), with dual thumb wheels and 90-degree scrolling user-friendly design.

The Digital Power Module is able to give a super clean linear output, a 0.25mV ripple wave, high-speed transient response (4uS), and supporting precise fine-tuning. It can accept a DC input between 4.2V and 30V, which is reduced up to 2.7V after startup.

MDP-XP Smart Digital Power Supply Kit

The device has been designed with protections like input overvoltage, under-voltage protection, anti-reverse connection protection, anti-backflow protection, overtemperature protection, and over-current protection

Specifications:

  • Input – DC4.2V-30V (after startup 2.7V), 100mA-6A, supports QC3.0
  • Output – 30V/5A, 90W
  • Adjustment rate
    • Load adjustment rate <±0.01^%
    • Power adjustment rate <±0.01^%
  • Ripple and noise – 250uVrms/3mVpp
  • Transient response time – ≤4uS
  • Line loss compensation range – 5mR-100mR
  • Data record – Max storage: 7MB, Max recording time: 24 hours.
  • Others
    • Automatically shut down and enter the micro-power mode.
    • Support USB firmware upgrade.
    • Support user calibration

The device is available for purchase from Seeedstudio for $199.90 with limited stock. At that price, you will get an MDP-M01 display module, an MDP-P905 power module, a 2.5mm Audio to Micro USB Cable, two 4mm Banana Plug to Alligator Clip, a  2.5mm Audio to USB Type-A, and a user manual.

More information is available on the product page.

Nitpick but you go from modular power supplies to expanding Arduinos that aren’t (for the most part) power supplies and that makes the whole thing seem a bit made up.

Ouch. Go on ebay and get yourself a second hand keysight or agilent desktop power supply for $50 bucks. Get four of them for $200 and stack them up if you need lots of different rails.

30V/5A 90W

Math doesn’t add up. 30V/3A maybe. And if 5A is the overall current limit, and you want 5V output, that will give you just 25W.

It should not add up. Typical power rating for bench PSU should be read as 30V OR 5A with 90W cap. That would be 30V3A or 18V5A.

90W wireless power transfer between the modules?

This product seems to be developed by Miniware: http://www.miniware.com.cn/product/mdp-xp-digital-power-supply-set/
This is the same company that made the popular TS80 and TS100 portable soldering irons. The MDP-XP is also available on Banggood so I am not sure what kind of deal they have with Seeedstudio.
