POWER SUPPLY DESIGN LEADER N2Power enters the DC-DC power supply market with comprehensive 125 watt and 160 watt families based on its proven XL125 and XL160 AC-DC Series products. Years of experience with these chassis translates directly to confidence right from the start of production. UNMATCHED POWER DENSITY Eight XL125 DC-DC models and seven XL160 DC-DC models deliver a range of outputs from 3.3V to 48V. Physical dimensions of just 1.25” x 3” x 5” mean easy integration into existing designs replacing older, less efficient products. They are also ideally suited for new OEM designs where the small formfactor frees up valuable “real estate” that can be reallocated to other purposes. HIGH EFFICIENCY IN A SMALL PACKAGE These new DC-DC Series supplies deliver up to 90% efficiency. Our unique design reduces energy consumption and generates less heat. It requires little forced air cooling, increases reliability and economy of operation. Comparisons of efficiencies show that our supplies can reduce losses up to 50%. REPEATABLE QUALITY Each N2Power supply undergoes complete functional testing and a multi-hour burn-in to insure that every unit meets stringent quality requirements. Each power supply design is rigorously tested by UL, DEMKO, and European agencies, with scheduled factory audits to ensure ongoing compliance.

POWER SUPPLY DESIGN LEADER N2Power enters the DC-DC power supply market with comprehensive 125 watt and 160 watt families based on its proven XL125 and XL160 AC-DC Series products. Years of experience with these chassis translates directly to confidence right from the start of production. UNMATCHED POWER DENSITY Eight XL125 DC-DC models and seven XL160 DC-DC models deliver a range of outputs from 3.3V to 48V. Physical dimensions of just 1.25” x 3” x 5” mean easy integration into existing designs replacing older, less efficient products. They are also ideally suited for new OEM designs where the small formfactor frees up valuable “real estate” that can be reallocated to other purposes. HIGH EFFICIENCY IN A SMALL PACKAGE These new DC-DC Series supplies deliver up to 90% efficiency. Our unique design reduces energy consumption and generates less heat. It requires little forced air cooling, increases reliability and economy of operation. Comparisons of efficiencies show that our supplies can reduce losses up to 50%. REPEATABLE QUALITY Each N2Power supply undergoes complete functional testing and a multi-hour burn-in to insure that every unit meets stringent quality requirements. Each power supply design is rigorously tested by UL, DEMKO, and European agencies, with scheduled factory audits to ensure ongoing compliance.
