ZK-5KX DC0.6-36V 5A 80W Adjustable Buck Boost Power Supply Module

ZK-5KX DC 0.6–36V 5A Adjustable Buck Boost Power Supply Module is a versatile and high-performance DC-DC converter designed to provide precise voltage regulation for a wide range of electronic projects. This module utilizes a sophisticated buck-boost topology, which allows it to maintain a stable output voltage regardless of whether the input voltage is higher or lower than the desired set point. Consequently, you can use a variety of power sources, such as batteries or unregulated wall adapters, to drive sensitive equipment safely. The integrated LCD display provides real-time monitoring of voltage, current, power, and capacity, offering a professional user interface for benchtop testing. Furthermore, the ZK-5KX includes multiple software protection mechanisms to prevent damage from over-voltage or over-current conditions. Therefore, this power supply module serves as an indispensable tool for hobbyists and engineers who require a portable, adjustable, and reliable power solution.

Key Features:

• Automatic Buck-Boost: The module seamlessly transitions between step-up and step-down modes to ensure the output remains constant despite input fluctuations.
• Digital Control Interface: A dedicated rotary encoder and crisp LCD screen allow for fine-tuned adjustments and clear visibility of operational parameters.
• Comprehensive Protection: It features built-in safeguards against under-voltage (LVP), over-voltage (OVP), over-current (OCP), over-power (OPP), and over-temperature (OTP).
• High Efficiency: Optimized circuitry minimizes energy loss during conversion, which reduces heat generation and extends component lifespan.
• CC and CV Modes: Supports both constant current and constant voltage operation, making it suitable for battery charging and LED driving.
