Industrial DC Power Unit

This 1500W switching supply converts 100-120VAC or 200-240VAC input into selectable 12V, 24V, 36V or 48V DC output. It delivers up to 125A at 12V for test benches, LED installations or industrial equipment requiring regulated DC power. Professional installation by a qualified electrician is strongly recommended because no wiring cables, switch or mounting screws are included. The unit suits users who need a single high-current rail with adjustable voltage trim.

Thermal Behaviour and Efficiency

Rated efficiency reaches 0.85 at 230VAC input and 25°C ambient. Protections cover short circuit, overload above 110-150 percent of rated power and over-voltage, with auto recovery once the fault clears. A full-load burn-in test of 1100 cycles is performed at the factory. Operating range spans -20°C to +60°C at 20-90 percent relative humidity. The aluminium shell weighs 1850g and measures 240x125x75mm for passive heat dissipation.

Accessory Impact

No cables, on/off switch, screws or printed instructions ship with the unit. Buyers must supply appropriately rated conductors, a suitable enclosure and an input selector set to the local mains voltage before energising. The +V ADJ trimmer allows fine output adjustment but provides no remote-sense or digital control. Users requiring plug-and-play connectivity or bundled mounting hardware should consider a different form factor.

Questions about this item

How do I wire the AC input and DC output terminals on this 1500W supply, and what is the step most people get wrong?

Connect L to live, N to neutral, +V to positive DC and -V to negative DC; the step most people get wrong is forgetting to set the 100-120VAC or 200-240VAC selector before applying power.

What maintenance will this 1500W unit need over its service life?

No user-serviceable parts inside; keep the ventilation slots clear and operate between -20°C and +60°C so the 85% efficiency design can run at full load without thermal shutdown.

At what point does the 1500W supply hit its limit during sustained operation?

Overload protection activates above 110% of rated power, shutting down the output until the fault is removed and the unit auto-recovers.
