Peak current rating on V1 (main output) is 120% of max, lasting 3 second with max of 10% duty cycle. 2. Combined output power of V1 plus fan supply and standby supply should not exceed max power rating. 3. +/-20% tolerance of Vfan includes the factors of set point accuracy, line and load regulation. 4. Air flow over long edge (either direction) required for air flow rating. See mechanical drawing, Figure 7 on page 11. 5. More than 800K hours MTBF is to be calculated according to Bellcore TR-332 standard current edition at 25 ºC. The ABC600 SERIES AC-DC/DC-DC power supply can operate using AC or DC input. It is a highly efficient front-end power supply. The PFC stage adopts an analog controller in continuous conduction mode to achieve high power factor and high efficiency. The DC/DC stage is fully DSP controlled and employs soft switching resonant techniques in conjunction with synchronous rectification for high efficiency and better thermal control. With a wide input operational voltage range and minimal linear derating of output power with temperature, the ABC600 SERIES maximizes power availability in demanding server, network, and other high availability applications. The supply is convection cooled or fan cooled and ideally suited for integration with a matching airflow path. An active OR-ing MOSFET on the output ensures no reverse current and renders the supply ideally suited for operation in redundant power systems. The always-on standby output Vsb (5 Volts) provides power to external power distribution and management controllers. It is protected with an active OR-ing diode for maximum reliability. In addition, the PMBus allows full monitoring of the supply, including input and output voltage, current, power, and internal temperatures. Current share signal (V1_Ishare) is used for current sharing, and the difference between two units is within 2.5 A if system load is more than 25% of full load. The current share signal (V1_Ishare) voltage shall be a linear function Vcs = 8 x Iout/Imax for a single power supply. Example: for ABC600-1012G, VCS is 8 V at 50 A loading; Imax is 50 A of ABC600-1012G. Figure 1. ABC600 SERIES Block Diagram |
