(40.3mm) to fit in 1u applications. net2?s high-performance active power factor circuitry meets en61000-3-2 requirements for compliance with european power line harmonic requirements for 2001. a multifunctional output terminal allows connection to #8 ring lugs, 0.25? quick disconnects, cable connectors, and pcb-mounted connectors. description advance product release
