Key Product Highlights
High Current Handling: Capable of delivering up to 9A, making it one of the most powerful compact buck converters in its class.
Dual Precision Potentiometers: Features high-precision trimmers for independent adjustment of both Output Voltage and Output Current (CC/CV).
Advanced Thermal Design: Equipped with large dual-aluminum heatsinks to dissipate heat effectively during high-load operations.
Low Ripple Output: Optimized for stable power delivery, ensuring your sensitive electronics are protected from voltage spikes.
CC/CV Functional: The Constant Current (CC) feature makes this an excellent choice for high-power LED drivers and specialized battery chargers (Li-Ion, Lead-Acid).
Electrapac Pro Tip: When drawing more than 5A or exceeding 150W for extended periods, we recommend adding a small cooling fan to the heatsinks to ensure maximum lifespan and performance.
DIY Lab Bench Power Supply: Convert an old laptop adapter into a versatile, adjustable power source.
High-Power LED Driver: Safely drive 10W to 100W COB LEDs with precise current control.
Battery Charging: Ideal for charging 12V or 24V battery systems from a higher voltage source.
Industrial Automation: Step down 24V industrial rails to 12V or 5V for sensors and microcontrollers.
At Electrapac, we source only high-grade power modules that meet rigorous performance standards. We help you power your innovations with reliability and efficiency.
