Status and Control protected. A LO permits writing to the EEPROM. This signal is pulled HI internally by the power supply. Signal Definitions Output signals All signals and outputs are referenced to Output return. These include ‘Vstb return’ and ‘Signal return’. Output current monitor (Imon): A voltage level proportional to the output current is present on this pin. The signal level is 0. 2V per amp ± 0.25V. Input Signals Voltage programming (Vprog): An analog voltage on this signal can vary the output voltage from -42Vdc to -58Vdc. The equation of this signal is: Vout = 20x (Vprog) 2.1 < Vprog < 2.9 If Vprog is ≥ 4V, or left open the programming signal is ignored and the unit output is set at the setpoint of -54Vdc. Load share (Ishare): Single wire analog signal between power supplies connected in parallel. The Ishare pins should be tied together for power supplies. No resistors or capacitors should get connected to this pin. Remote ON/OFF: Controls the presence of the main -54Vdc output voltage. This is an open collector, TTL level control signal. This signal needs to be pulled HI externally through a resistor. Maximum collector voltage is 12Vdc, maximum sink current is 1mA. Logic 1 turns ON the -54Vdc output, while a Logic 0 turns OFF the -54Vdc output. A turn OFF command either through this signal or firmware commanded would turn OFF the -54V output. Enable: This is a short signal pin that controls the presence of the -54Vdc main output. This pin should be connected to ‘output return’ on the system side of the output connector. The purpose of this pin is to ensure that the output turns ON after engagement of the power blades and turns OFF prior to disengagement of the power blades. Write protect (WP): This signal protects the contents of the external EEPROM. When left open the EEPROM is write November 20, 2012 AC OK: TTL compatible open collector. Maximum sink current 20mA, max voltage is 12Vdc. A (HI) on this signal indicates that the input voltage is present within limits. DC OK: TTL compatible, open collector. Maximum sink current 20mA, max voltage is 12Vdc. A (HI) on this signal indicates that the output voltage is present. Over temp warning: TTL compatible, open collector. Maximum sink current 20mA, max voltage is 12Vdc. A (HI) on this signal indicates that temperatures are normal. If an over temperature should occur, this signal would delay pulling LO for approximately 10 seconds. The unit would restart if internal temperatures recover within normal operational levels. Fault: TTL compatible, open collector. Maximum sink current 20mA, max voltage is 12Vdc. A (HI) on this signal indicates that no faults are present. This signal activates for OTP, OVP, or AC fault. PS Present: Connected to ‘output return’. Its intent is to indicate to the system that a power supply is present. This signal may need to be pulled HI externally through a resistor. Interrupt: A TTL compatible status signal, representing the SMBusAlert# feature of the i2C protocol in the power supply. This signal needs to be pulled HI externally through a resistor. Maximum sink current ≤ 4mA and the pull up resistor should be tied to <5Vdc. Open collector (HI) on this signal indicates that no Interrupt has been triggered. ©2012 General Electric Company.

Page 4 GE CAR1248TN series rectifier Input: 90Vac to 264Vac; Output: -54Vdc @ 1200W Serial Bus Communications – CAR1248TN The I²C interface facilitates the monitoring and control of various operating parameters within the unit and transmits these on demand over an industry standard I²C Serial bus. Device addressing: The microcontroller (MCU) and the EEPROM have the following addresses: MCU EEPROM 1 1 Address Bit Assignments (Most to Least Significant) 0 1 1 A2 A1 A0 0 1 0 A2 A1 A0 Iout [01]: Output current read back, data LSB followed by MSB. Example; readback 021Fh, convert into its decimal equivalent and multiply by the constant, Iout=543 x 0.042 = 22.8A R/W R/W Address lines (A2, A1, A0): Up to eight (8) modules to be addressed on a single I²C bus. The pins are pulled HI internal to the power supply. For a logic LO connect to ‘Output Return’ Serial Clock (SCL): Host generated, this signal needs to be pulled up externally ensuring that rise and fall time timing and the maximum sink current is in compliance to the I²C specification. Serial Data (SDA): This is a bi-directional line that needs to be pulled up externally ensuring that rise and fall time timing and the maximum sink current is in compliance to the I²C specification. Command code: All registers are 16 bits, written as LSB followed by MSB. All A/D’s are 10 bit (1024 steps). All constants can be fine-tuned to compensate for manufacturing tolerances; Name CMD Access Default /Name Vout Iout Temperature ON/OFF Ilimit Vset Vprog OT trip OT recover DC_OK_HI DC_OK_LO 00 01 02 03 04 05 06 07 08 09 0A R R R R/W R/W R/W R R/W R/W R/W R/W -54 - STATUS 0B R 0C 0D7C R R/W Firmware EEPROM November 20, 2012 Bits Constant 0.102 0.042 0.005 1 – OFF, 0 – ON 25 -54 The default value is -54Vdc Example; readback 0211h, convert into its decimal equivalent and then multiply by the constant, Vout = 529 x 0.102 = 54Vdc All signals are referenced to ‘Signal Return’. Device Vout [00]: Output voltage read back, returns the voltage on the anode side of the or’ing function, data LSB followed by MSB. 0.042 0.094 Vout= 20 x Vprog 120 0.005 110 0.005 55.6 0.102 52.4 0.102 Input 0 1-LL AC_OK 1 DC_OK 2 OT 3 1-normal Fault 4 Intrpt 5 OV 6 DC_INT 7 Temperature [02]: Temperature read back, data LSB followed by MSB. Example; readback 037Bh, convert into its decimal equivalent and multiply by the constant, temp = 891 x 0.005 = 4.36. In the table below this corresponds to 25C Data Temp C Data Temp C Data Temp C 4.83 4.78 4.72 4.65 4.56 4.46 4.35 4.21 4.06 3.89 -5 0 5 10 15 20 25 30 35 40 3.71 3.51 3.3 3.09 2.88 2.67 2.46 2.25 2.06 1.88 45 50 55 60 65 70 75 80 85 90 1.7 1.54 1.4 1.26 1.14 1.03 0.93 0.84 95 100 105 110 115 120 125 130 ON/OFF [03]: A logic ‘1’ turns OFF the -54V output of the power supply. Ilim [04]: This feature lowers the current limit from the default values of 0253h (595), corresponding to 25A at high line and 01EFh (495) corresponding to 20.8A at low line. The delivered output current cannot exceed the maximum power capacity of the unit. At high line the power supply is limited to 1200W, thus, at -48Vdc the output current is limited to 25A. Example: At high line, reduce the current limit to 20A. Compute the data to be sent to the controller; 20 / 0.042 = 476. The hex equivalent of this decimal data is 01DCh. The data should be sent across the bus as LSB [DC] followed by MSB [01]. Vset [05]: Changes the output voltage via i2c, if the Vprog hardware signal is > 4Vdc. If the Vprog pin voltage level is < 4Vdc, this command is ignored. The output voltage setting must be between -42 – -58Vdc. The default value is 023Eh, corresponding to -54Vdc. Example; set the output to 48Vdc. Compute the data to be sent to the controller; 48 / 0.094 = 510. The hex equivalent of this decimal data is 01FEh. The data should be sent across the bus as LSB [FE] followed by MSB [01]. ©2012 General Electric Company. All rights reserved. Page 5 GE CAR1248TN series rectifier Input: 90Vac to 264Vac; Output: -54Vdc @ 1200W Vprog [06]; Reads back the hardware configured analog voltage program value via i2c. MCUeeprom [0D – 7C]: 125 bytes of information may be stored in the EEPROM section of the micro controller starting from register location 0Dh. Each byte of data needs to be stored into its specific register location, one byte at a time. The value of Vprog can range from 2.1V to 2.8V. Example: set the output to 44Vdc. From the equation determine that Vprog = 2.2. The 10bit D/A is set for the range of 0 – 5Vdc, therefore with a resolution of 1024 bits each bit is 0.00488V. So the corresponding value to enter is 2.2/0.00488 = 451 decimal. This corresponds to 01C3h. The data should be sent across the bus as LSB [C3] followed by MSB [01]. External EEPROM A separate EEPROM, with its own i2c address and with write_protect capability, provides 128 bytes of memory. This is a standard i2c compliant generic EEPROM with a single byte for its memory location. Standard i2c command structure applies. OT trip[07] and OT recover[08]; Configures the OT shutdown and recovery levels. The default values are; The following FRU_ID information is stored in this EEPROM OT trip: 120C corresponds to 1.03/0.005 = D3h OT recover: 110C that corresponds to 1.26/0.00488 = 0102h Example: Change the recovery temperature to 100C. In the look up table above the corresponding level is 1.54. Divide by the conversion ration, 1.54/0.00488 = 315 dec. Converting to its hex equivalent yields 013B hex. The data should be sent across the bus as LSB [3B] followed by MSB [01]. DC_OK_HI[09] and DC_OK_LO[0A]: Changes the DC_OK signal comparator level. The default values are; Start Location Length 00h 07h 08h 0Ch 0Dh 1Eh 1Fh 7 1 4 1 17 1 1 Value 20h 20h 20h Description Serial number, ascii space Date code [YYWW] ascii space Code CAR1248TNBXXZ01A ascii space Revision LEDs DC_OK_HI: 0221h, corresponding to 55.6V DC_OK_LO: 0201h, corresponding to 52.4V Three LEDs are located on the front faceplate. The AC_OK LED provides visual indication of the INPUT signal function. When the LED is ON GREEN the power supply input is within normal design limits. Example: Change the upper level of comparison to 55V. Determine the corresponding register value setting; 55/0.102 = 539dec. This is equivalent to 021Bh. The data should be sent across the bus as LSB [1B] followed by MSB [02]. When the DC_OK LED is GREEN the DC output is present. STATUS [0B]: All read backs are two bytes and so read back two bytes but ignore the MSB. When the FAULT_LED is RED then a fault condition exists and the power supply may not provide output power. The table below further defines these states: Firmware [0C]: Reads back the latest firmware revision.
