DP100 Lab

Native macOS app for the Alientek DP100 digital power supply. Replaces the Windows-only official software with a modern, fast, and beautiful interface built for macOS.

Features

• Real-time monitoring — Voltage, current, power, temperature at 20Hz
• Live chart — V/I/P traces with pause, hover tooltips, series toggle, speed control
• Output control — ON/OFF, set voltage/current with validation
• 10 presets (P0-P9) — View, edit, save to device, activate
• System settings — OPP, OTP, backlight, volume, reverse protection, auto-output
• CSV data logging — Record telemetry to disk with millisecond timestamps
• Voltage/Current scanning — Automated sweep with configurable range and step
• Protocol debug logging — Full TX/RX packet log for troubleshooting
• macOS native — Vibrancy, overlay titlebar, dark/light mode, SF Pro font

Requirements

• macOS 12+ (Apple Silicon)
• Alientek DP100 connected via USB-A (slave mode)

Install

Download the latest .dmg from Releases.

Note: The app is not signed with an Apple Developer certificate. After installing, run:

xattr -cr "/Applications/DP100 Lab.app"

This removes the macOS quarantine flag. Alternatively, right-click the app → Open → Open.

Or build from source:

Protocol

Custom USB HID protocol library (dp100_proto) built from scratch through hardware testing and manufacturer DLL analysis. Key discoveries:

Flag	Operation
0x20	Apply to output (immediate)
0x40	Save to preset storage (flash)
0x80	Activate preset (switch)
0x40 opcode len=0	Read system settings
0x40 opcode len=8	Write system settings
