Frequently Asked Questions for 120V 20A DC Power Supplies
Q: Can I operate a 0–120V 20A DC power supply in both Constant Voltage (CV) and Constant Current (CC) modes?
Yes. All our 0–120V 20A power supplies support automatic, seamless CV/CC crossover. You can set the target voltage up to 120V and current limit up to 20A independently to safeguard sensitive Devices Under Test (DUT).
Q: What input voltage and power outlet is required for a 0–120V 20A 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 0–120V 20A power supplies run continuously 24/7 under 100% full load?
Yes. All power supply units undergo 100% full-load high-temperature burn-in testing prior to shipment. They utilize high-margin MOSFET/IGBT power stages and dual-ball-bearing temperature-controlled fans, specifically qualified for continuous industrial burn-in and laboratory testing.
Q: How can I purchase a 0–120V 20A power supply, and do you support corporate PO/PI?
All listed models are available with transparent catalog pricing and in-stock inventory for direct online purchase via credit/debit card and PayPal. For universities, research labs, and corporate procurement requiring internal PO approval or wire T/T, you can also generate an official corporate Proforma Invoice (PI) quotation PDF with official wire banking details directly from any model page. All orders include free worldwide DDP door-to-door air express transit (~10 business days) and a 1-year warranty.
