6 PACS12CE Control Signal PSON The PSON is an internally pulledlow(gnd), externally pulledup (3.3 ) signal to enable/disable the 12 output. This activelow pin is also used to clear any latched fault condition. The configuration diagram of PSON is shown in Figure 3: Typical configuration diagram of PS_KILL is as following: PACS12CE CC System PSON Output oltage 12 DC R On Off PS_KILL PACS12CE System GND CC R Figure 4: Configuration diagram of PS_KILL 1 KΩ GND PSON PRESENT The PRESENT is used to indicate to a power distribution unit controller that a supply is plugged in. The configuration diagram of PRESENT is shown in Figure 5: Figure 3: Configuration diagram of PSON PACS12CE System CC PS_KILL The PS_KILL pin help to implement the PSU hotplug. The PS_KILL input is activelow and is located on a recessed pin on the connector and is used to disconnect the main output as soon as the power supply is being plugged out. This pin should be connected to signal GND in the system. GND PRESENT R PS_KILL Connect to the system Yes No Figure 5: Configuration diagram of PRESENT The logic of PRESENT is as following: PRESENT Connect to the system Yes No 6

7 PACS12CE Control Signal PS_INTERRUPT The low active open collector signal indicates that the power supply is experiencing a problem, warning or fault that the system agent should investigate. PS_INTERRUPT will be low if one of the following situations occurs: Input undervoltage (Delay time from ACOK low to PS_INTERRUPT high will be less than 1 μs.) Input overvoltage (Delay time from ACOK low to PS_INTERRUPT high will be less than 1 μs.) Output overvoltage Output overcurrent Overtemperature or undertemperature Fan fault The logic of PS_INTERRUPT is as following: PS_INTERRUPT PSU (PACS12CE) abnormal normal DCOK DCOK is an open collector signal to indicate that the output is within the regulation limits of the power supply. When the output voltage falls below regulation limits, DCOK is asserted to a low state. About the detail of regulation limits is as following: DCOK ACOK Output oltage regulation limits 11.8 DC out output overvoltage protection out < 11.8 DC or out > output overvoltage protection threshold ACOK is an open collector signal to indicate that the AC input has been removed for a time sufficiently long, or when the AC input voltage falls below regulation limits, ACOK is asserted to a low state. About the detail of regulation limits is as following: ACOK Input oltage AC power is normal AC power is abnormal 7

10 PACS12CE Remote sense 12 DC output has sense lines implemented to compensate for voltage drop on load wires. The maximum allowed voltage drop is Sense+ Sense GND Load Figure 13: Configuration diagram for remote sense Load sharing Up to eight PACS12CEs can be paralleled for redundant configurations. All the I_Monitor pins need to be interconneted in order to activate the sharing function. Protection Characteristic Output Overvoltage Protection When the output voltage exceeds the output overvoltage protection threshold, the PSU will enter a latch off mode. The latch can be cleared by toggling the PSON signal or by an AC input recycle. The delay time from PSON high to PSON low should be more than 1 s. The delay time from AC off to AC on should be more than 15 s. Output Overcurrent Protection 1.After the remote sense is applied, the volt at the output terminal is less than 12.8 DC. 2. If the sense pin is not used, it should be left open. Internal Cooling Fans Power supply will power for the internal fans. It contains fan speed control circuits to vary the fan speed. If one of the paralleled PACS12CEs has no output while the communication remains normal, the fan can operate at minimum speed. Figure 14 shows the detail about the wind tunnel. Fan When the output current exceeds the output overcurrent protection threshold, the PSU will enter a latch off mode. Output overcurrent shall be maintained for a period of 1s before the PSU enter a latch off mode. The latch can be cleared by toggling the PSON signal or by an AC input recycle. The delay time from PSON high to PSON low should be more than 1 s. The delay time from AC off to AC on should be more than 15 s. Overtemperature Protection The power supply is protected against over temperature conditions caused by loss of fan cooling or excessively high ambient temperature. In an overtemperature condition, the PSU shuts down, the DCOK goes low and the bicolor LED changes from green to red. When the fault condition is removed, the PSU will automatically restart.

14 PACS12CE PMBus Communication The PSU contains internal EEPROM device accessible through PMBus communication. As long as the unit is connected to system backplane which is providing 12 DC power, unit FRU data shall be accessible without AC inputs. Pins A, A1, and A2 are also allocated at the power supply connector for selecting the PMBus address of communication devices inside the power supply. The PSU address capability is as following table: PSU 1# 2# 3# 4# 5# 6# 7# 8# A2/A1/A FRU address xa xa2 xa4 xa6 xa8 xaa xac xae The PACS12CE develops the following monitoring functions and faults detection functions. Monitoring functions: Input voltage Input current Input power Output voltage Output current output power output voltage setpoint Faults detection functions: Reports alarms for input under/overvoltage protection Reports alarms for output under/overvoltage Reports alarms for fan faults Reports alarms for under/overtemperature Reports alarms for output overcurrent, and short circuits Appendix B describe the FRU data to be stored in power supply EEPROM by vendor. For more information, please refer to PMBus_Specification_Part_I_Rev_12, PMBus_Specification_Part_II_Rev_12, Appendix A. Safety Precautions You are advised to provide two power inputs for the system. Power configuration in N+N mode is preferred. The following figure shows the power configuration in 3+3 mode. Configure a circuit breaker (with a rated current not less than 16 A) for each PSU. The rated current of the upstream circuit breaker for each power input is recommended to be not less than 4 A. The PSU should be properly grounded. Otherwise, it will be damaged due to a lightning strike. Figure 17: Application configuration in system 14
