Industrial 450W Single-Output Supply

The myVolts SE-450-48 is a 450W enclosed switching power supply designed for fixed-voltage industrial and lighting installations. It delivers a regulated 48V output at up to 9.4A, making it suitable for LED strips, light boxes, control cabinets and automated sorting equipment.

Build Integration and Cooling

The unit accepts a selectable AC input range via an onboard switch and includes active surge current limiting to protect upstream circuitry. Forced-air cooling is provided by a built-in DC ball-bearing fan, while a remote-sense function compensates for voltage drop across long cable runs to the load.

Sustained-Load Behaviour

Comprehensive protection circuits cover short circuit, overload, over-voltage and over-temperature events, allowing continuous operation in demanding environments. A front-panel LED indicates power-on status, and the supply carries UL approval for safety compliance.

Questions about this item

What is the first limit reached when the SE-450-48 runs continuously at its 48 V 9.4 A rating?

The built-in over-temperature protection will trigger first if the forced-air cooling cannot remove the heat generated at full 450 W output.

How loud and hot does the unit get during all-day operation?

A built-in DC ball-bearing fan provides forced-air cooling; the supply carries UL approval and includes over-temperature shutdown for sustained loads.

What AC input must already be available on site for this supply to work?

The AC input range is selectable by a switch on the unit, so the installer must provide a matching mains voltage.
