No component will damage. The protection is hiccup mode. It tries to restart 5 times (2 second off, 200 ms on) and then locks out. Overcurrent protection (OCP) If a PSU is overloaded higher than the values listed below, it will “softly shut down”, meaning reduce its voltage by 3 V and wait for 6 ms (to give enough time for BBU to take over). If overload is still there, PSU can shut down. After an overload fault, PSUs will retry to sync together and turn on once every 5 s.

  • Average power more than 3.45 kW for 10 s.
  • Average power more than 3.6 kW for 100 ms.
  • Repetitive pulse power more than the pulse power envelope specified (up to 150% load). Overvoltage protection (OVP) The rectifier will shut down for DC output voltage exceeding 52.5 V and the reacting time will not exceed 200 ms. For DC output voltage will never exceed 54 V (fast OVP). Overtemperature protection (OTP) The rectifier employ over temperature protection for both ambient over temperature and internal thermal temperature to protect the rectifier. The rectifier will shut down under over temperature condition and recover after certain period after the over temperature condition is removed. The OTP circuit incorporate built in hysteresis such that the power supply does not oscillate on and off due to temperature recovering condition. The OTP event shall be reported as a fault condition. Note 1 - For surge current capabilities, see Pulse Load Operation. Note 2 - Compliance will be verified using a 0.1 uF capacitor connected locally to the oscilloscope probe tips during this measurement.

4 advancedenergy.com PSU voltage should drop by 3V after its holdup energy is lost by 50% or 30J. Here, 24J or 40% of holdup energy is allocated for pulse power. As the result, PSU should meet the following pulse power envelope shown below without triggering BBU (reducing voltage by 3 V, which happens when holdup energy is reduced by 50%). In order to meet the Pulse power requirements as the graph above, the dc-dc converter should meet the following absolute pulse power requirement as shown below. This graph comes from the worst case of Pstart as 100%.

advancedenergy.com 5 Per the scheme above, for the worst case that AC outage and pulse power happens at the same time (and pulse power remains constantly), PSU will transition to BBU seamlessly as calculated in the table below. Graph below shows the PSU requirement to transition to BBU in case of AC outage. PSU voltage should drop by 3V after its holdup energy is lost by 50% or 30J. In case that AC voltage is available, but constant overload of up to 150% happens, PSUs will drop voltage by 3 V per the scheme above and share power with BBUs. PSUs will retry to sync together and increase the voltage once every 5 s.

6 advancedenergy.com Input Over Current Protection The rectifier will incorporate primary fusing on both phase and return lines for input over-current protection to meet product safety requirements. Fuses shall be selected to prevent nuisance trips. Fuse may be internal to unit and need not be user serviceable. AC inrush current will not cause the fuse to blow under any conditions. No rectifier operating condition will cause the fuse to blow unless a component in the rectifier has failed. This includes DC output overload and short-circuit conditions. Fuse will be approved by UL for an interrupt rating of at least 25 kA. PSU fuse will be in coordination with datacenter Tapbox breaker curve as given below. NEC breakers are 20 and 30 A (two ac feeds go to the power shelf – one PSU per input ac phase feed). IEC breaker is normally 32 A (one ac feed goes to the power shelf – two PSUs per input ac phase feed). (Ignore 16A breaker.) Input Over Voltage and Under Voltage Protection The rectifier contain protection circuitry such that application of an input voltage below the minimum specified in section "Input Specification" on page 2 will not cause any damage to the rectifier and “softly shuts down” while operating. The rectifier will “softly shut down” if the input voltage is over 345 V for 20 ms or 309 V for 50 ms as shown in the graph below.

advancedenergy.com 7 Output Power / Current Protection If a PSU is overloaded higher than the values listed below, it will “softly shut down”, meaning reduce its voltage by 3 V and wait for 6 ms (to give enough time for BBU to take over and then turn off output.). If overload is still there, PSU will shut down. After an overload fault or in case of 3 V drop if there is no overload, PSUs will retry to sync together and turn on once every 5 s.

  • Average power more than 3.45 kW for 10 s.
  • Average power more than 3.6 kW for 100 ms.
  • Repetitive pulse power more than the pulse power envelope specified (up to 150% load). Constant Current mode will be triggered at 155% load. Output reduce voltage by 3 V if any of the conditions below are met:
  • Constant current mode dwell for 10 ms.
  • Output droops < 48.5 V due to constant current mode. Output Short Protection The rectifier includes short-circuit protection to protect the rectifier and attached load in the case of an output short-circuit or other output overload condition. If the rectifier voltage is lower than 10 V (short circuit condition), the rectifier shuts off immediately. No component damage. The protection will be implemented with a hiccup mode. it tries to restart 5 times every 5 s and then locks out. PSUs will sync using sync_start after shut down to power up together. Over Temperature Protection The rectifier employ over temperature protection for both ambient over temperature and internal thermal temperature to protect the rectifier. The rectifier will “softly shut down” under over temperature condition and recover after certain period after the over temperature condition is removed. The OTP circuit incorporate built in hysteresis such that the power supply does not oscillate on and off due to temperature recovering condition. The OTP event will be reported as a fault condition. TIMING Random Timer and Synchronization Under any conditions of dissipative load, capacitive load, temperature, with or without backup voltage connected to the PSU, Max time for PSU to be “power-up ready” after AC voltage starts is 2.5 s. After “power-up ready”: When there is no DC voltage on the bus (first AC turn on) the power shelf will be randomized with 0 to 2 s window to give each power shelf a random turn-on time (six PSUs turn-on is synchronized). When there is DC voltage on the bus higher than 44 V for 0.1 second (BBU is discharging), the power shelf will be randomized with 0 to 5.5 seconds window to give each power shelf a random turn-on time (six PSU turn-on is synchronized). The power shelf will trun on with only 1 PSU inserted into any slot. Note: The random numbers above will be dynamically generated immediately after each AC recycle, and not generated one time and then stored in the EEPROM for future usages. Item Description Min Max Unit T_power-up_ready Time for PSU to be power-up ready 1.0 2.5 s T_random_noBBU 0 to 2 seconds initial turn on random delay without BBU discharging 0 2.0 s Ton_noBBU Time 51 VDC turns on after shelf receives AC input without BBU discharging. 1.0 4.5 s T_random_BBU 0 to 5.7 seconds turn on random delay after BBU discharging 0 5.5 s Ton_BBU Time 51 VDC turns on after shelf receives AC input with BBU discharging. 1.0 8.0 s Tsync After all PSUs in the shelf are ready to start till when 51 VDC will start 2.0 5.0 ms Tmax_ON_noBBU Max PSU turn-on time without BBU in case of sync failure 6.0 7.5 s Tmax_ON_BBU Max PSU turn-on time with BBU in case of sync failure 9.5 11.0 s

8 advancedenergy.com TRANSITION AND SYNCHRONIZATION REQUIREMENTS Start-up (0 V to 51 V) Transition Procedure Each PSU has a small circuit as shown below and the circuit output (called SYNC_START) of all PSUs are connected together on the power shelf backplane. 1) Each PSU sets its uC Digital output signal (Do_SyncReady_L) to low when the PSU is ready to turn on the output. 2) Only PSU in SLOT #1 generates random timer and set Do_SyncReady_L to low when ready and random timer is finished. 3) The PSUs will turn on the output when the uC Digital input sync signal (DI_Sync_H) is high. 4) If DI_Sync_H kept stuck low for 3 s more than the max random timer limit (which is 2 s without BBU and 5.5 s with BBU), the PSU will turn on immediately. 5) If PSU1 is not installed or its Do_SyncReady_L stuck low, the other PSUs shall turn on when the DI_Sync_H is high. In this case random timer doesn't exist. Please refer to section "Pulse Load Operation" on page 4 for the timing and constant current value requirements during the cold startup.

48 V to 51 V Transition Procedure

The same SYNC_START circuit as shown above is used here. 1) When PSU enters 48V output mode, it sets “Do_SyncReady_L” signal to HIGH. 2) If there is no over power or over current condition for 5s, each PSU sets “Do_SyncReady_L” signal to LOW. 3) If signal “DI_Sync_H” is HIGH (HIGH when all PSUs in parallel ready to adjust), then change constant current level to 120% and adjust output from 48 V to 51 V. 4) If the signal “DI_Sync_H” is stuck LOW for 5 s, the PSU shall adjust its output from 48 V to 51 V. 5) If the PSU output did not reach 51 V in 5s, then it return to 48 V mode, set constant current level to 155%, and go to step 1). Refer to diagram below that covers both 48 V to 51 V and 51 V to 48 V transitions.

advancedenergy.com 9 TRANSITION AND SYNCHRONIZATION REQUIREMENTS The Power shelf includes a slot for a power shelf management controller (PMC) to monitor and control various rectifier parameters. The PMC is connected to rack management controller or facility level monitoring through a monitoring & control interface. If the PMC fails or is not provided, the power system is able to operate normally. The PMC is powered from the 48 V bus directly. CONTROL AND MONITORING SIGNALS

51 V to 48 V Transition Procedure

This transition and conditions associated with it was explained in section "over power/current protection" on page 7 and section "PSU-BBU transition" on page 5. No synchronization is needed in this case. Refer to diagram above that covers both 48 V to 51 V and 51 V to 48 V transitions.
