The +12V and +3.3V are DC DC referenced to Signal return. Address lines (A2, A1, A0): These signal pins allow up to eight (8) modules to be addressed on a single I²C bus. The pins are POE isolation: The main 54V output is fully isolated from DC pulled HI internal to the power supply. For a logic LO these the rest of the power supply, complying with the POE isolation delaypins should be connected to ‘Output Return’ requirements of IEEE802.3af. Serial Clock (SCL): The clock pulses on this line are generated by the host that initiates communications across the I²C Serial bus. This signal is internally pulled-up to 3.3V via a 1.2kΩ Control Signals resistor.

PMBus™ compliance: The power supply is fully compliant to the Power Management Bus (PMBus™) rev1.2 requirements. Status signals Master/Slave: The ‘host controller’ is always the MASTER.

The signal shall not assert for a Clock stretching: The ‘slave’ µController inside the power DC minimum of 10ms after loss of AC power supply may initiate clock stretching if it is busy and it desires to delay the initiation of any further communications. During DC_OK_L: A TTL compatible status signal representing the clock stretch the ‘slave’ may keep the clock LO until it is whether the output voltage is present. This signal needs to be ready to receive further instructions from the host controller. pulled HI externally through a resistor. The maximum clock stretch interval is 25ms.

This signal needs to be and refrain from issuing the next clock signal, until the clock pulled HI externally through a resistor. line is released, or it needs to delay the next clock pulse beyond the clock stretch interval of the power supply. If an over temperature should occur, this signal would pull LO for approximately 10 seconds prior to shutting down the Note that clock stretching can only be performed after power supply.

Implementing the latch-off If a fault still persists after the issuance of the clear_faults mechanism permits a synchronized restart that guarantees command the specific registers indicating the fault are reset the simultaneous restart of the entire system. again. A synchronous restart can be implemented by; WRITE_PROTECT register (0x10): Used to control writing to the PMBus device. The intent of this command is to provide 1. Issuing a GLOBAL OFF and then ON command to all power protection against accidental changes. All supported supplies, command parameters may have their parameters read, 2. Toggling Off and then ON the Remote ON/OFF signal regardless of the write_protect settings. The contents of this 3. Removing and reapplying input commercial power to the register can be stored to non-volatile memory using the entire system. Store_default_code command.

Enable all writes 00 Auto_restart: Auto-restart is the default configuration for Disable all writes except write_protect 80 recovering from over-current and over-temperature Disable all writes except write_protect and 40 shutdowns. OPERATION An overvoltage shutdown is followed by three attempted restarts, each restart delayed 1 second, within a 1 minute Vout_OV_warn_limit (0x42): OV_warning is extremely useful window. If within the 1 minute window three attempted because it gives the system controller a heads up that the restarts failed, the unit will latch OFF. If less than 3 shutdowns output voltage is drifting out of regulation and the power occur within the 1 minute window then the count for latch supply is close to shutting down. Pre-amative action may be OFF resets and the 1 minute window starts all over again. taken before the power supply would shut down and potentially disable the system. Status_word (0x79): returns two bytes of information. The upper byte bit functionality is tabulated in the Status_word Vout_OV_fault_response (0x41): The power supply can be section. The lower byte bit functionality is identical to programmed to latch at a level set by Vout_OV_fault_limit by Status_byte. changing the response to 0x40. Invalid commands or data: The power supply notifies the Vout_UV_fault_response (0x45): The power supply can be MASTER if a non-supported command has been sent or invalid programmed to latch at a level set by Vout_UV_fault_limit by data has been received. Notification is implemented by setting changing the response to 0x40. the appropriate STATUS and ALARM registers. OT_fault_ response (0x50): The power supply can be programmed to either resume operation (0xC0) or latch (0x40) at a level set vy OT_fault_limit. Restart after a latch off: Either of four restart possibilities are LEDs available. The hardware pin Remote ON/OFF may be turned Two LEDs are located on the front faceplate. The AC_OK LED provides OFF and then ON. The unit may be commanded to restart via visual indication of the INPUT signal function. When the LED is ON i2c through the Operation command by first turning OFF then GREEN the power supply input is within normal design limits. turning ON . The third way to restart is to remove and reinsert The second LED is the DC_OK LED. When solid GREEN there are no the unit. The fourth way is to turn OFF and then turn ON ac faults and DC output is present. When blinking GREEN there is an power to the unit. The fifth way is by changing firmware from apparent engagement problem with the output connector. latch off to restart.
