    The KT750 is a low-profile, multiple-output, 750W power supply with a 3.3V high current main output and active input power factor correction (PFC). The active PFC not only provides compliance with EN61000-3-2, but also accommodates a wide-input voltage range of 90 to 264 vac for global applications. The PFC input stage is followed by a half-bridge converter that provides a proven architecture for high reliability requirements. Compliance is to FCC/VDE Class B specs, with the switcher also offering safety agency approvals from UL, CSA, TUV and the CE Mark. A wide array of output configurations are available, and active current sharing on all three outputs are designed to simplify N+1 redundant requirements in fault-tolerant applications.
