What N2Power, Inc does
N2Power, Inc is a US-based manufacturer of switch-mode open-frame and enclosed AC-DC power supplies serving OEM markets. Founded in 1999 in Southern California and headquartered in Camarillo, California, N2Power operates as a wholly owned subsidiary of Qualstar Corporation (OTC: QBAK) following Qualstar's 2002 acquisition. The company designs and produces 20+ standard product families across three power tiers — 40–100W ultrasmall open-frame units, 125–180W mid-range models with N+1 redundancy, and 240–750W high-density units including medical-certified variants — leveraging patented ultrasmall packaging technology to achieve power densities above 15 W/cu in and efficiency ratings up to 94%. Product features include fanless convection cooling to full power, 2xMOPP/4,000 VAC medical isolation for BF patient-contact applications, N+1 redundancy via active current sharing and built-in OR-ing MOSFETs, digital power management via I2C/PMBus on the flagship XL750, and compliance with UL/IEC/EN 62368-1 (ITE), UL/IEC/EN 60601-1 3.1 edition and EN 60601-1-2 4th edition (medical), and RoHS.
The company monetizes through direct OEM hardware sales across industrial, ITE/broadcast, medical, gaming, and lighting end-markets, supplemented by a custom design-to-spec service called OPSM (Optimized Power Systems Manufacturing) that delivers fully integrated power assemblies with wiring harnesses, connectors, and enclosures from prototype through volume production. N2Power operates a consultative enterprise field-sales motion with free sample programs for qualified OEM evaluations, complemented by a partner/reseller portal, a CMS Distribution channel agreement signed August 2025, and international sales and support offices in Singapore and Shenzhen, China. Customers are primarily B2B OEMs requiring safety-certified, compact, high-efficiency power solutions, with product lifecycles anchored by 3-year standard warranties and multi-year OEM program contracts.
