CNC USB Adjustable Regulated Power Supply Module — 15W Constant Voltage & Current (CV/CC)
A compact 15W adjustable regulated power supply module with both constant voltage (CV) and constant current (CC) modes, controllable via USB interface or onboard potentiometers. Provides a continuously adjustable output voltage (typically 0–30V) and current limit (0–2A), making it suitable for battery charging, LED driver testing, electroplating, and DIY bench power supply applications where precise voltage and current control is required.

CV vs CC Mode Explained
| Mode | Behaviour | Use Case |
|---|---|---|
| CV (Constant Voltage) | Output voltage fixed; current varies with load | Powering fixed-voltage circuits, LED strips |
| CC (Constant Current) | Output current fixed; voltage varies with load | Battery charging, LED current control, electroplating |
| CV+CC | Voltage and current both limited; switches mode at threshold | Safe battery charging (CC until full, then CV) |
Typical Applications
- Battery Charging: CC/CV charging for Li-ion, LiPo, NiMH, and lead-acid batteries with adjustable charge voltage and current limit
- LED Testing & Binning: Constant current LED testing at precise forward current levels for LED characterisation and binning
- Electroplating: Constant current power supply for small-scale electroplating, anodising, and electrolytic processes
- CNC & Electronics Lab: Adjustable bench power supply for CNC controller testing, PCB debugging, and component characterisation
- Motor Speed Control: Variable voltage supply for DC motor speed testing and characterisation
- DIY Power Supply: Core module for building a custom bench power supply with digital voltage and current control
FAQ
Q: Can I control this module from a computer via USB?
A: Yes. The USB interface allows digital voltage and current setpoint control from a PC using the provided software or custom serial commands. The onboard potentiometers provide manual control when USB is not connected.
Q: Is this suitable for charging a 12V lead-acid battery?
A: Yes. Set CV to 14.4V (for AGM) or 14.8V (for flooded) and CC to the appropriate charge current (typically C/10 of battery capacity). The module will automatically switch from CC to CV as the battery approaches full charge.
