300W Variable Bench DC Power Supplies

Q: What input voltage and power outlet is required for a 300W power supply?

Models up to 3000W support fixed 110V–130V AC without de-rating, as well as standard 220V–240V AC. Models 1500W and above are shipped with heavy-duty industrial cables (without household 15A plugs) to connect directly to industrial circuits.

Q: Can these 300W power supplies run continuously 24/7 under 100% full load?

Yes. These laboratory-grade power supplies utilize high-margin power transistors (MOSFET/IGBT) and dual-ball-bearing temperature-controlled fans, specifically qualified for non-stop industrial burn-in and production line testing.

Q: Are custom output voltages or currents available at this 300W power level?

Yes. If your application requires a specific V/A combination at the 300W rating that is not listed in our standard matrix, our engineering team provides custom configurations with fast 3–5 day sampling. Contact us for a custom quotation.

Regulated 300W DC power systems available in 15V–300V voltage and 1A–20A current configurations. Compare technical specifications, check live stock and direct USD pricing for instant online checkout or formal Proforma Invoice (PI).
