7 / 8 page Data Sheet Compact Power Line CP2725AC54 Front-End Power Supply Lineage Power 7 Signal Definitions All hardware alarm signals (Fault, PFW, OTW, Power Capacity) are open drain FETs. These signals should be pulled HI to either 3.3V or 5V. Maximum sink current 5mA. An active LO signal (< 0.4Vdc) state. All signals are referenced to Logic GRD unless otherwise stated. Contact your Lineage Power representative for more details. Function Label Type Description Output Enable Enable Input If shorted to LOGIC_GRD, the rectifier output is enabled when using I 2C mode of operation. May also be toggled to reset a latched OFF rectifier. Function not available in RS485 mode. Power Fail Warning PFW Output An open drain FET; normally HI, indicating output power is present. Changes to LO at least 5msec before the output voltage is lost. I 2C Interrupt Alert#_0 Alert#_1 Output Interrupt signal via I 2C lines indicating that service is requested from the host controller. This signal pin is pulled up to 3.3V via a 10kΩ resistor and switches to active LO when an interrupt occurs. Rectifier Fault Fault Output Indicates that an internal fault exists. An open drain FET; normally HI, changes to LO. Module Present MOD_PRES Output Short pin, see Status and Control description for further information on this signal. ON/OFF ON/OFF Input Short pin, connects last and breaks first; used to activate and deactivate output during hot-insertion and extraction, respectively. Ref: 54_OUT (-DC) Protocol select Protocol Input See Status and Control description for further information on this signal. Ref: 54_OUT (-DC). Margining Margin Input Allows changing of output voltage through an analog voltage input or via resistor divider. Over-Temperature Warning OTW Output An open drain FET; normally HI, changes to LO approximately 5°C prior to thermal shutdown. Power Capacity POWER_CAP Output Open drain FET; Used to indicate rectifier operation mode; HI indicates 2725W operation and LO indicates 1200W operation. Rectifier address Unit_addr Input Voltage level addressing of rectifiers within a single shelf. Ref: 54_OUT (-DC). Shelf Address Shelf_addr Input Voltage level addressing of rectifiers within multiple shelves. Ref: 54_OUT (-DC). Back bias 8V_INT _ Diode OR’ed 8Vdc drain; used to back bias microprocessors and DSP of failed rectifier from operating rectifiers. Ref: 54_OUT (-DC). Mux Reset Reset Input Resets the I 2C lines to I2C line 0. Standby power 5VA - 5V at 0.75A provided for external use by either adjacent power supplies or the using system. Current Share Ishare - A single wire interface between each of the power unit forces them to share the load current. Ref: 54_OUT (-DC). I 2C Line 0 SCL_0, SDA_0 Input I 2C line 0. I 2C Line 1 SCL_1, SDA_1 Input I 2C line 1. RS485 Line RS_485+ RS_485- Input RS485 line. |
