AUGUESLD DC-DC Buck-Boost 120W Power Converter

The AUGUESLD SK-120X is a compact 120W DC–DC buck–boost power converter with a full-color display that delivers adjustable CC/CV output from 0–36V and up to 6A for lab, bench, or field use.

The SK-120X merges a wide input range and precise output control into a small module designed for electronics hobbyists, technicians, and makers. It accepts DC 6–36V and produces 0–36V with constant-current and constant-voltage regulation, supporting up to 120W power and 6A peak current. A full-view VA color LCD offers live readouts of voltage, current, and power so you can monitor parameters at a glance.

How does the SK-120X manage voltage and current for bench testing?

This unit provides both constant-voltage (CV) and constant-current (CC) modes, allowing you to set precise output limits for safe component testing and debugging. The buck–boost topology lets the module step the input up or down to maintain the chosen output across a wide input range.

• Input: DC 6.0–36V flexible source compatibility
• Output: DC 0–36V adjustable for diverse projects
• Max current: 6A with thermal management to protect components
• Max power: 120W suitable for small lab supplies and chargers

What protections are included to keep connected devices safe?

Several built-in safety protections prevent damage to the converter and your load when operating in real conditions. These protections help safeguard against wiring mistakes, overloads, and thermal stress without requiring external circuitry.

• Anti reverse connection prevents damage from reversed input wiring
• Anti reverse current stops current feeding back into the source
• Under-voltage, over-voltage, and over-current protections enforce safe operating windows
• Over-temperature and over-power protections reduce thermal and electrical risk

How is the SK-120X controlled and monitored during use?

The SK-120X uses a full-view VA color LCD to present clear, real-time measurements for voltage, current, and power. Its interface and display make it easy to fine-tune setpoints and confirm behavior during charging, testing, or DIY builds.

• Color LCD shows voltage, current, and power simultaneously
• Intuitive controls let you adjust CV/CC setpoints quickly
• Real-time feedback reduces trial-and-error and speeds setup
• Compact module form factor fits on workbenches or inside custom enclosures

Can the SK-120X be used with solar panels or for small charging setups?

Yes — the converter’s wide input range and buck–boost behavior make it suitable for integrating with variable sources like small solar panels or battery systems. It can act as a regulated charge controller or a stable supply for accessories and testing rigs.

• Compatible with variable DC sources such as solar arrays within 6–36V
• Provides stable CV/CC output for controlled charging of batteries or capacitors
• Small footprint allows panel-mounted or enclosure-mounted installations
• Useful for off-grid experiments, field repairs, and prototype power delivery

Who this product is for: The AUGUESLD SK-120X fits electricians, electronics hobbyists, makers, and technicians who need a compact, adjustable, and protected DC power supply. It’s also a practical choice for anyone building or testing battery chargers, DIY power systems, or portable lab setups where precise voltage/current control and clear readouts matter.
