SeaSonic 400W Active PFC F0 1U Power Supply (SS-400H1U)

SeaSonic 400W Active PFC F0 1U Power Supply (SS-400H1U)This is a Seasonic industrial power supply is 80 PLUS efficiency rated and it features a high reliability ball bearing fan. Fully modular cables and easy-swap connectors add a new dimension to its versatility, while the Seasonic Smart and Silent Fan Control (S2FC) system make it a silent performer. These units comply with the latest PFC harmonics (IEC1000-3-2 and EN61000-3-2 standards) and are protected against short circuit, over voltage and over power. On the 3.3 V rail there is no minimum load requirement for this unit to work properly.Intel EPS1U v2.1 and ATX 12 V v2.2 compliantForward converter circuitHigh efficiency and reliability for industrial levelEasy-swap connector design40 mm double ball bearing fanFully modular cablesSmart and Silent Fan Control (S2FC)Zero minimum load on 3.3 V railShort circuit protection on all outputsOver voltage protectionOver power protection100 % HiPot test100 % Burn-in, high temperature cycled on/offPFC harmonics compliance: IEC1000-3-2 and EN61000-3-2 standardsDC Outputs+3.3 V+5 V+12 V Combined-12 V+5 VsbTotal continuous powerInput Type20 A21 A29 A0.8 A3 A400 WFull range130 W (max.)348 WSpecificationsInput frequency50 / 60 HzEfficiency (220 V AC - 240 V AC, full load)83 % (typical)Efficiency (100 V AC - 120 V AC, full load)80 % (typical)Dielectric withstand, input to frame/ground1800 VAC, 1 secDielectric withstand, input to output1800 VAC, 1 secLine regulation 1 % (typical)Load regulation 5 % (typical)Cross regulation 5 % (typical)MTBF, full load @ 25 C ambient (excl.
