Industrial AC/DC Adapter 36 W

This 12 V 3 A switching power supply converts 100 V to 240 V AC mains into 36 W of regulated DC power. It suits installers and technicians running LED strips, CCTV cameras, wireless routers or similar low-voltage equipment indoors. The aluminium case measures 3.34 in by 2.28 in by 1.45 in and provides three independent output channels each rated at 3 A. Buyers who need higher wattage or outdoor-rated enclosures should look elsewhere.

Silent convection cooling and protection

No fan is fitted; the vented aluminium housing dissipates heat passively for silent operation. Built-in safeguards include automatic over-voltage cut-off, thermal cut-off, overload cut-off and short-circuit protection to keep connected devices safe during faults. The supplier advises loading the unit to no more than 80 % of its rated capacity for reliable long-term use.

12 V 3 A maximum output current

The single decisive specification is the 3 A DC output limit at 12 V, giving 36 W total across the three channels. Any device or combination of devices drawing more than 3 A will exceed the adapter’s capability and trigger protection shutdown.

Questions about this item

How do I mount the adapter and wire the three output channels without overloading a single terminal?

Secure the aluminium case (3.34 in × 2.28 in × 1.45 in) on a flat indoor surface with screws through the mounting tabs, then distribute the load across all three channels so no channel exceeds 3 A.

What component will need attention after long-term indoor use?

The fanless aluminium chassis relies on convection; dust buildup in the ventilation holes reduces cooling, so periodic cleaning with compressed air is the only routine upkeep.

What limit appears first when the unit runs continuously at full load?

The automatic thermal cut-off engages once the case temperature rises past the internal threshold, shutting down output until the unit cools.
