Peak current rating on V1 (main output) is 120% of max, lasting 3 second with max of 10% duty cycle.
Combined output power of V1 plus fan supply and standby supply should not exceed max power rating.
+/-20% tolerance of V
fan
includes the factors of set point accuracy, line and load regulation.
Air flow over long edge (either direction) required for air flow rating. See mechanical drawing, Figure 7 on page 11.
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 V
sb
(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_I
share
) 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_I
share
) voltage

NOTES:
1.
The output noise and ripple measurement was made with 20 MHz bandwidth using a 6 inch twisted pair, terminated with a 10 uF tantalum
capacitor in parallel with a 0.1 uF ceramic capacitor.
2.
For ABC600-1048G/52G, the current share abs (I1-I2) should be less than 3 A at light load (< 25% of full load).

The Output is protected against an overload or a Short Circuit for indefinite duration. The unit shall meet this requirement when in
general operating conditions. Over current limit should meet below curve within +/-1.5 A tolerance, and the unit is allowed to

Bel Power Solutions provides with its “Bel Power Solutions I2C Utility” a Windows® XP/Vista/Win7 compatible graphical user
interface allowing the programming and monitoring of the ABC600 Series Front-End. The utility can be downloaded on
www.belpowersolutions.com and supports both the PSMI and PMBus™ protocols.
The GUI allows automatic discovery of the units connected to the communication bus and will show them in the navigation tree. In
the monitoring view the power supply can be controlled and monitored.
