DROK 48V 10A Variable AC to DC Power Supply 480W

The DROK 48V 10A 480W variable power supply is an adjustable AC-to-DC converter that delivers DC 0–48V at up to 10A for LEDs, CCTV, lab equipment and other low-voltage devices.

This compact, bench-ready unit converts household AC (selectable 110V/220V) into a fine-adjustable DC output with 0.1V resolution. Built-in cooling, an LED display and multiple safety protections make it practical for hobbyists, electronics workbenches, small installations and lighting projects where a customizable, stable DC source is required. No internal current regulation is provided — the supply can deliver up to 10A depending on the load.

How do I adjust voltage and read the output?

Voltage is set with the embedded potentiometer on the front panel and shown on the bright LED screen with 0.1V precision. Turn the knob slowly while monitoring the display to find your target voltage; the screen reflects changes immediately for precise setup.

• Adjustable range: DC 0–48V, useful presets include 5V, 9V, 12V, 24V, 36V, 48V
• Display resolution: 0.1V increments for accurate tuning
• Potentiometer recessed for accidental-movement protection
• Selectable input: switch between 110V and 220V before use

What safety features protect my devices?

The DROK converter includes standard protections to reduce risk during normal operation: overload protection, over-voltage protection and short-circuit protection. These safeguards help the supply shut down or limit output when unsafe conditions occur, protecting connected equipment from damage.

• Overload protection prevents sustained currents above rated limits from harming the unit
• Over-voltage protection guards sensitive loads from excessive voltage spikes
• Short-circuit protection quickly responds to wiring faults
• Thermal control via heat sink and fan keeps operating temperatures in check

How does the unit manage heat and continuous operation?

Thermal management combines an aluminum heat sink and an automatic cooling fan that engages under higher loads. The fan runs quietly and activates only when needed, allowing the converter to operate reliably during extended usage while keeping audible noise low.

• Aluminum heat sink dissipates steady-state heat from power components
• Automatic fan starts on higher temperature or load demand
• Low audible noise designed for workshops and indoor use
• Stable performance at up to the rated 10A provided load conditions are met

What applications suit this adjustable power supply?

This converter is versatile for many DC-powered tasks: supplying LED strips and landscape lighting, testing CCTV cameras, bench power for electronics projects or powering small lab devices. It's a practical choice when a single unit that can cover multiple common voltages is needed.

• LED and landscape lighting where various voltages are required
• CCTV and surveillance camera systems during setup and testing
• Electronics bench work and small lab equipment requiring adjustable DC
• Automotive or RV projects needing stable DC sources within the 0–48V range

Who is this for? If you are an electronics hobbyist, installer or technician who needs a flexible, high-power DC source without complex installation, the DROK 48V 10A 480W variable power supply is built to fit your bench, workshop or small installation needs. It’s especially useful when you require precise voltage control across a wide range, quiet thermal management, and standard protection features. Note that the unit supplies up to 10A based on load characteristics and is not a programmable constant-current source — choose it for voltage-adjustable applications and make sure connected devices draw below the 10A maximum.
