The high-density, front-toback airflow rectifier is designed for minimal space utilization and is highly expandable for future growth. It is provided with RS485 and dual-redundant I2C communications busses that allow it to be used in a broad range of applications. The flexible feature set makes this front-end power supply an excellent choice for applications requiring modular ac-to-dc bulk intermediate voltages, such as in distributed power.

Below -5°C, the rise time is approximately 5 minutes to protect the bulk capacitors. 2. Complies with GR947 which calls for a minimum rise time proportional to output load. 3. On start-up, a 20 second fold-down current limit is activated to permit system start-up when units are plugged in one at a time. Beyond 20 seconds, hiccup mode of operation with approximately a 10% duty cycle is enabled. A latched mode current limit can be activated via an I2c command. During hiccup performance the power supply would shut down when the output voltage falls below 39Vdc.

Lineage Power 4 Data Sheet Compact Power Line CP2725AC54 Front-End Power Supply Status and Control The rectifier provides three means for monitor/control: analog, PMBus compliant I2C, or RS485 for interfacing to Lineage Power controllers or battery plants. Details of analog controls are provided in this data sheet under Signal Definitions. Lineage Power will provide separate application notes on PMBus protocol for users to interface to the CPL rectifiers. Contact your local Lineage Power representative for details. Module Present Signal: This signal has dual functionality. It can be used to alert the system when a module is inserted. Has a 500W resistor in series between this signal and Logic GRD. An external pull-up should not raise the voltage on the pin above 0.25Vdc. If raised the pin is raised to 5Vdc the write_protect feature of the EEPROM is enabled. Protocol Select: Establishes the communications mode of the power supply, between analog/I2C and RS485 modes. For RS485, connect 750 – 3.92kΩ pull-down resistor to 54_OUT(-DC). Enable: On/Off control when either PMBus communications or analog functions are utilized as configured by the Protocol pin. This pin must be pulled low to turn ON the main output of the power supply. The power supply will turn OFF if either the Enable or the ON/OFF pin is released. The Enable function does not work with the RS-485 protocol. This signal is referenced to Logic_GRD. ON/OFF: This is a short pin utilized for hot-plug applications to ensure that the power supply turns OFF before the power pins are disengaged. It also ensures that the power supply turns ON only after the power pins have been engaged. Must be connected to 54_OUT (-DC). Hot Plug When rapidly extracting and reinserting modules care should be taken to allow for discharging the internal bias supply so that a predictable restart could be achieved. The way to ensure that the circuit sufficiently discharges is to observe the spinning of the fans after an extraction. The unit should not be reinserted until the fans stop spinning. Control Definitions All signals are referenced to Logic GRD unless otherwise noted. See the Signal Definitions Table at the end of this document for further description of all the signals. Input Signals Margining: Setpoint of the rectifier can be changed via this input pin. Programming can be either a voltage source or a resistance divider. The margining pin is connected to 3.3Vdc via a 10kΩ resistor inside the rectifier. See graphs below. Output Signals Alert #: PMBus interrupt signal. Fault: This signal goes LO for any failure that requires rectifier replacement. Some of these faults may be due to: • Fan failure • Over-temperature condition • Over-temperature shutdown • Over-voltage shutdown • Internal Rectifier Fault Power Capacity: A HI on this pin indicates rectifier configured for 2725W operation; a LO indicates rectifier configured for 1200W operation. An open circuit on this pin reverts the voltage level back to the original setting.
