Installation & use

How to install Indoor Switching Power Supply 250W (12V/24V)

Indoor use only. Keep 5 cm clearance around the case and never cover the perforations.

Step by step

  1. Set the 115/230 VAC selector switch to match your mains before connecting anything — wrong setting destroys the unit.
  2. Fix the PSU to a solid surface with the terminal block accessible; leave free air on all sides.
  3. Wire AC input L / N to the terminal block through a switch or MCB; earth the FG terminal where provided.
  4. Wire the strip feed to V− / V+ output. For runs over 5 m, feed from both ends or run a parallel bus cable.
  5. Adjust the voltage potentiometer only if the strip spec requires it — measure with a meter, do not guess.
  6. Load test at full brightness for 30 minutes; the case will run warm, which is normal.

Before you power up

  • IP20 housing — keep away from water, dust and direct weather.
  • Load no more than 80 % continuously (200 W on a 250 W unit) for longest life.
  • Fanless design relies on airflow: an enclosed cupboard needs vents or a small fan.

Typical applications

  • Indoor cove and ceiling strip runs
  • Cabinet and shelf lighting power
  • Retail display and light box supply
  • Workshop and signage bench supply
