  • TypeAT
  • Delivers 450 W continuous power for demanding industrial and LED loads
  • 3 V at 75 A supports high-current low-voltage applications
  • Switch-selectable AC input range adapts to local mains voltages
  • Built-in remote sense compensates voltage drop over long cable runs
  • UL approved with short-circuit, overload, over-voltage and over-temperature protections

Industrial 3.3 V 450 W supply

This myVolts SE-450-3.3 unit delivers 450 W at a fixed 3.3 V output rated for 75 A. It is built for LED lighting, light-box installations, industrial control cabinets and monitoring systems that require a single high-current rail.

Check input switch and cooling clearance

The AC input range is selected by a physical switch on the enclosure; verify the setting matches your local mains voltage before connecting power. Forced-air cooling uses a built-in DC ball-bearing fan, so allow unrestricted airflow around the ventilation openings.

Enclosed chassis with remote sense and protections

The metal enclosure carries UL approval and includes short-circuit, overload, over-voltage and over-temperature protection. A built-in remote-sense function compensates for voltage drop on long cable runs, and an LED indicator shows power-on status at a glance.

Questions about this item

Does the SE-450-3.3 include any cables or connectors, or must I buy them separately?

The unit is supplied as an enclosed power supply with screw terminals for input and output; no cables or connectors are included.

How do I choose between the SE-450 output voltages such as 3.3V, 5V or 12V?

Each model is a fixed-voltage unit; select the SE-450-3.3 for 3.3V at 75A, or choose the 5V, 12V, 15V, 24V, 36V or 48V version that matches your load.

What does the 450W rating mean when the supply is installed in a cabinet with a built-in fan?

It delivers a continuous 450W at 3.3V 75A with forced-air cooling from the internal DC ball-bearing fan, protected against short circuit, overload, over-voltage and over-temperature.
