Variable DC Power Supply Ratings: Compare All Models & Specifications

1. AC Input Voltage & Wiring Standards

Models rated up to 3000W support fixed 110V–130V AC input without power de-rating, operating at 100% full capacity, as well as standard 220V–240V AC. Units rated at 1500W and above ship with heavy-duty industrial open-wire leads for direct termination to industrial circuit breakers. High-power units above 3000W require industrial 200V–240V AC or 3-phase AC.

2. Full-Load Thermal Burn-In Protocol

Every unit undergoes 100% continuous 4 to 8 hour full-load burn-in testing in thermal chambers before packaging. Output power stages utilize industrial MOSFET and IGBT devices backed by dual-ball-bearing temperature-regulated cooling fans.

3. Automatic CV/CC Solid-State Crossover

All listed power supplies feature seamless automatic crossover between Constant Voltage (CV) and Constant Current (CC) modes, preventing transient overcurrent or inductive voltage spikes from damaging the device under test (DUT).

4. Direct Online Purchasing & Corporate Proforma Invoice (PI)

All listed models support instant direct online checkout with transparent pricing and real-time stock allocation. For corporate and university purchase orders, procurement teams can also generate an official corporate Proforma Invoice (PI) quotation PDF with wire banking terms directly. All orders include free global DDP door-to-door air express transit (~10 business days).
