SKU CH-R3Z8-SH8KH

A 500W switching power supply delivering 48V at 11A for LED strips, engraving machines and surveillance, with a galvanized aluminium shell for heat dissipation

  • Product typeAT
  • 500 W output powers demanding LED strips and engraving machines
  • 48 V 11 A delivers stable voltage for surveillance and advertising lighting
  • Hollow chassis design improves heat dissipation in high-temperature environments
  • Galvanized aluminium shell resists corrosion for extended service life
  • Copper-core transformer windings handle sustained loads without overheating

500 W 48 V Industrial Power Supply

This 500 W switching unit delivers a steady 48 V at 11 A for equipment that needs reliable DC power. It targets operators of engraving machines, LED strip installations, advertising signage and surveillance systems.

Galvanized Aluminum Shell

The hollow chassis design promotes passive heat dissipation so the supply tolerates high ambient temperatures without active cooling. A copper-core transformer winding resists thermal stress and contributes to stable output under continuous load.

500 W Continuous Capacity

The unit comfortably powers typical LED arrays, engraver electronics and monitoring gear within its 500 W rating. It is not suited for applications that demand higher voltage rails, redundant supplies or battery-backed operation.

Questions about this item

Will the galvanized aluminum shell need any treatment to maintain its corrosion resistance?

The galvanized coating protects the aluminium shell from oxidation; no additional treatment is required under normal indoor use.

At 11 A output, what limits continuous operation before the unit shuts down?

The 500 W rating is the thermal ceiling; sustained loads near 11 A at 48 V will trip over-temperature protection if airflow is restricted.

How much heat and fan noise should I expect when this supply runs all day at full load?

The hollow-shell design relies on passive convection; surface temperatures rise noticeably and a small internal fan produces audible airflow noise during extended high-power use.
