Alientek-DP100

A .NET library for communicating with the Alientek ATK-MDP100 programmable power supply over USB using the HID protocol. This library provides basic control and monitoring capabilities such as reading voltage/current, setting output state, and configuring limits.

Note: This project is based on scottbez1/webdp100, which served as the foundation for understanding the communication protocol and device behavior.

Features

• Connect/disconnect from ATK-MDP100 device via HID
• Read real-time output voltage and current
• Turn output on or off
• Set voltage and current limit values

---

Supported Device

• Product Name: ATK-MDP100
• Vendor ID: 0x2E3C
• Communication: USB HID

---

Example Usage

using Alientek_DP100;

var device = new AlientekDP100();

if (device.Connect())
{
    Console.WriteLine("Connected!");

    device.SetVoltage(5.0f);          // Set output voltage to 5V
    device.SetCurrentLimit(1.5f);     // Set current limit to 1.5A
    device.SetState(true);            // Enable output

    if (device.GetVoltageCurrent(out float voltage, out float current))
    {
        Console.WriteLine($"Voltage: {voltage} V, Current: {current} A");
    }

    device.Disconnect();
}
else
{
    Console.WriteLine("Device not found.");
}
