3300 W Power Module SPAFCBK-11G

6600 W Power Shelf SPSFCBK-18

Power Module Blank Panel SPSFCBK-12BP01 Battery Module Panel SPSFCBK-12BP02 The SPAFCBK -11G AC/DC power module is a MCU/DSP controlled, highly efficient front -end power supply. It incorporates resonant-soft-switching technology to reduce component stresses, providing increased system reliability and very high power conversion efficiency. The PFC stage is digitally controlled u sing a state -of-the-art digital signal processing algorithm to guarantee best efficiency and unity power factor over a wide operating range. The main DC/DC stage (12.6 V / 3300 W) uses soft switching resonant techniques in conjunction with synchronous rectification. An active OR-ing device on the output ensures no reverse load current and renders the supply ideally suited for operation in redundant power systems. The auxiliary DC/DC stage (54 VDC / 300 W) uses a soft switching resonant topology and is also protected with an active OR -ing device for maximum reliability. The DC/DC converter from the battery input (3600 W) provides power to the internal high voltage bus and allows the outputs to continue up to 90 s during AC outage. The battery charger stage (52.5 V / 270 W) re-charges the battery backup unit (BBU). Status information is provided with a front-panel LED. The RS485 bus allows full monitoring of the supply, including input and output voltage, current, power, and internal temperatures. The same RS48 5 bus supports the bootloader to allow field update of the firmware in the MCU and the DSPs. The supply is cooled by a regulated fan and the air direction matches regular data center rack configurations. The fan speed is adjusted automatically depending on the supply temperature.

tech.support@psbel.com If a valid AC voltage is re -applied after less than 90 s, the shelf is transitioning back to AC operation without any deviation at the output. The time between AC voltage present and the transition from DC to AC operation is random from one shelf to the other to reduce the stress on the AC supply. BATTERY CHARGER BEHAVIOR The BBU decides on its own if it needs to be re -charged. Charging is requested by setting the BAT_CRG_EN flag. The PSU reacts on this flag by starting the 52.5 V battery charger with a controlled current ramp up. If the battery charger is running for more than 5 consecutive hours it is shut down and a failure is flagged. BBU STATE OF HEALTH CHECK The BBU will determine internally with a random logic if it needs to be tested, and requests with the BAT_SOH_CHK signal a test discharge. The power modules in the shelf decide based on their own and the other modules state, if they can do such a discharge. A state of health test discharge is only done if: - All 3 PSUs and BBUs are installed and communication is available - No other BBUs self-check is ongoing - No PSUs or BBUs failed - No BBU being charged at the moment - All PSUs in AC operation - PSU load is >500 W for at least 1 consecutive minute The BBU will determine if the test was valid and decide if it has reac hed the end of life and set the BAT_EOL signal if required.

If the auxiliary or the battery charger converter fail with a latching error, they will not shut down any of the other converters. The latching faults can be cleared/unlocked by disconnecting the supply from the AC mains for >2 s with a shutdown of the main output (not going into backup mode), or by toggling the PS_KILL input. INPUT FUSE Fast-acting 25 A input fuse (6.3 x 32 mm) in series with the L -line inside the power supply protects against severe defects. The fuse is not accessible from the outside and is therefore not a serviceable part. AC INPUT UNDER-VOLTAGE If the sinusoidal input voltage stays below the input undervoltage lockout threshold Vi on or falls below Vi off during operation, the supply will be inhibited. Once the input voltage returns within the normal operating range, the supply will return to normal operation again. If a good battery back-up unit is present, the unit can keep on operating for up to 90 s in case of AC outage. More details see in Section 3.4. DC INPUT UNDER-VOLTAGE There are several protection levels for the DC input under voltage. The BBU module will begin to protect itself at 33.8 V. Below this level, the PSU will protect at the Software under voltage threshold of 31.85 V, and this undervoltage is ignored during the first 15 seconds of backup to account for temporary dips during current ramp up. Finally, below this level is the hardware under voltage at 28 V.

comparator for the main, the auxiliary and the battery charger output. Once an OV condition has been triggered, the supply will shut down the converter. All three outputs have a software under voltage protection implemented. If the main output voltage falls below the under voltage level V1 UV for a time > tV1 UV trip it will latch-off. to restart the converter, if voltage is not restored before tVAUX UV latch the output will latch-off. restart the converter, and remain on indefinitely. control circuit will shut down the battery charger output and latch off. the output current is higher than IV1 OC SW for more than tV1 OC SW latch the output will latch off. to the output voltage. The supply will re-start after tV1 OC HW restart with a soft start. Figure 15. Current Limitation on V1
