ZK-4KX 4A 35W Programmable CNC Buck-Boost DC Power Supply – Adjustable Constant Voltage & Current Module in Pakistan

Overview

When working on electronics benches, building custom bench power supplies, or setting up solar battery chargers, traditional analog potentiometers make precise voltage and current regulation tedious and inaccurate. Fluctuating input voltages also make stable step-up and step-down conversions difficult without complex circuitry. The ZK-4KX 4A 35W Programmable CNC Buck-Boost DC Power Supply provides an advanced digital regulation solution, allowing makers and technicians to control and monitor voltage and current outputs precisely via a clear LCD interface.

Key Features

• Automatic Buck-Boost Operation: Seamlessly steps input voltage up or down to maintain a stable, user-defined output regardless of source fluctuations.

• High-Definition LCD Display: Real-time visual monitoring of input/output voltage, current, power, capacity (Ah), running time (h), and operational status.

• Constant Voltage & Current (CC/CV) Modes: Ideal for precise lab applications, LED driving, and safe multi-chemistry battery/solar charging.

• Robust Software Protection Suite: Features built-in adjustable thresholds for input undervoltage, output overvoltage, overcurrent, overpower, overtemperature, and timeout protection.

Technical Specifications

Common Applications

• DIY Bench Power Supply: Build a compact, variable laboratory power source tailored for electronics testing and prototyping.

• Solar & Battery Charging: Serves as an efficient charge controller module for 6V, 12V, or 24V batteries without needing backflow protection diodes.

Note to customers: Ensure proper ventilation or add an external cooling fan if pushing continuous output power past 35W toward the 50W maximum limit!
