XY-4KX Programmable CNC Buck-Boost Power Supply Module – 0.5-30V 4A 35W Digital LCD Volt Regulator

Overview 

The XY-4KX 35W Programmable CNC Power Supply Module is a high-precision, digitally controlled buck-boost converter that offers an exceptional balance of compact size and advanced functionality. Equipped with a dedicated segmented LCD screen, it simultaneously monitors input/output voltage, current, power, capacity (Ah), and operational runtime. Using its digital encoder knob, you can program precise constant voltage (CV) and constant current (CC) limits down to 0.01V and 0.001A. It is the ultimate tool for mobile field repairs, testing microcontrollers, or driving low-power robotics projects.

Key Features 

• True Buck-Boost Versatility: Can step-up or step-down voltage seamlessly. Input 5V to 30V and get a fully regulated output anywhere from 0.5V to 30V.

• CNC Digital Control: Unlike manual trim potentiometers that drift over time, the XY-4KX uses a digital rotary encoder for drift-free, precise adjustments.

• Comprehensive Parameter Tracking: The backlit LCD displays real-time statistics including Ah (Capacity) and Wh (Energy), making it an excellent battery capacity tester.

• Built-in Physical Protections: Includes anti-reverse input protection (prevents burnout if power is wired backwards) and anti-backflow protection at the output (safe for direct battery charging).

• Hardware Safety Suite: Fully armed with Over-Voltage Protection (OVP), Over-Current Protection (OCP), Over-Power Protection (OPP), Over-Temperature Protection (OTP), and Low-Voltage Protection (LVP).
