  • Converts 110-220V AC to stable 5V DC for LED strips
  • Delivers 4A current up to 20W for consistent brightness
  • Metal case with aluminum base dissipates heat effectively
  • Built-in short circuit, overload and over voltage protection safeguards components
  • Compact 85x60x33mm size fits tight installation spaces

AC to DC power supply for LED strips

The Vszerda unit converts 110-220V AC mains voltage into a regulated 5V DC output rated at 4A. It is intended for installers powering LED strip lights, modules or lamps in residential or commercial settings. The metal cased enclosure measures 85*60*33mm and operates between -10 and +50°C.

Protection features and wiring

Built-in short circuit, overload and over-voltage protection help safeguard connected LED loads. The supply has L and N terminals for AC input plus clearly marked -V and +V terminals for DC output, plus an ADJ potentiometer for fine voltage tuning. No wiring cables, switch, screws or instructions are included in the package.

20W capacity and limits

At 20W maximum output the driver comfortably runs shorter runs of 5V LED tape within its 4A current limit. Longer strips or higher-density modules that exceed 4A will require an additional power supply. Professional installation by a qualified person is strongly recommended due to the mains voltage input.

Questions about this item

Will the internal electrolytic capacitors need replacing after a few years of continuous use?

The unit uses a metal case with an aluminium base that acts as a heatsink, keeping capacitor temperatures lower during operation.

At what point does the over-temperature protection trip during sustained 4 A loads?

The specified working range stops at 50 °C; above that the internal protection will shut the supply down.

How much heat does the aluminium base dissipate when the supply runs at 20 W all day?

At 20 W output the base warms to a level that stays within the -10 °C to 50 °C operating window without a fan.
