10 / 15 page  GE Preliminary Data Sheet CAR2512TE Front-End Input: 90VAC to 264VAC; Output: 12 VDC @ 2500W; 3.3/5VDC standby @ 15W February 7, 2014 ©2013 General Electric Company. All rights reserved. Page 10 Linear Data Format The definition is identical to Part II of the PMBus Specification. All standard PMBus values, with the exception of output voltage related functions, are represented by the linear format described below. Output voltage functions are represented by a 16 bit mantissa. Output voltage has a E=9 constant exponent. The Linear Data Format is a two byte value with an 11-bit, two’s complement mantissa and a 5-bit, two’s complement exponent or scaling factor, its format is shown below. Data Byte High Data Byte Low Bit 7 6 5 4 3 2 1 0 7 6 5 4 3 2 1 0 Exponent (E) Mantissa (M) The relationship between the Mantissa, Exponent, and Actual Value (V) is given by the following equation: E M V 2 Where: V is the value, M is the 11-bit, two’s omplement mantissa, E is the 5-bit, two’s complement exponent PMBusTM Command set: Command Hex Code Data Byte Function Operation 01 1 W Output ON/OFF ON_OFF_config 02 1 R Set at 1D, can’t change Clear_faults 03 0 Clear Status Write_protect 10 1 W Write control Store_default_all 11 0 W Store permanently Restore_default_all 12 0 R Reset defaults Capability 19 1 R 30h, 400kHz, SMBAlert Vout_mode 20 1 R Vout constants Vout_command 21 2 W Set Vout Fan_command_1 3B 2 W Set fan speed in RPM Vout_OV_fault_limit 40 2 W Set OV fault limit Vout_OV_fault_response 41 1 W Vout_OV_warn_limit 42 2 W Set OV warn limit Vout_UV_warn_limit 43 2 W Set UV warn limit Vout_UV_fault_limit 44 2 W Vout_UV_fault_response 45 1 W Iout_OC_fault_limit 46 2 W Iout_OC_fault_response 47 1 W Latch or hiccup Iout_OC_warn_limit 4A 2 W Set OC warn limit OT_fault_limit 4F 2 W OT_fault_response 50 1 W Latch or hiccup OT_warn_limit 51 2 W Set OT warn limit Vin_OV_fault_limit 55 2 W Vin_OV_warn_limit 57 2 W Set OV warn limit Vin_UV_warn_limit 58 2 W Set UV warn limit Vin_UV_fault_limit 59 2 W Set UV shutdown Status_byte 78 1 R Status_word 79 2 R Status_Vout 7A 1 R Status_Iout 7B 1 R Status_input 7C 1 R Status_temperature 7D 1 R Status_CML 7E 1 R Status_other 7F 1 R Command Hex Code Data Field Function Status_mfr_specific 80 1 R Status_fan_1_2 81 1 R Read_Vin 88 2 R Read input voltage Read Iin 89 2 Read input current Read_Vout 8B 2 Read output voltage Read_Iout 8C 2 Read output current Read_temperature 8D 2 Read Temperature Read_fan_speed_1 90 2 In RPM Read_fan_speed_2 91 2 In RPM Read_Pout 96 2 Read_Pin 97 2 PMBus revision 98 1 Mfr_ID 99 5 FRU_ID Mfr_model 9A 16 Mfr_serial 9E 15 Mfr_Vin_min A0 2 Mfr_Vin_max A1 2 Mfr_Iin_max A2 2 Mfr_Pin_max A3 2 Mfr_Vout_min A4 2 Mfr_Vout_max A5 2 Mfr_Iout_max A6 2 Mfr_Pout_max A7 2 Mfr_Tambient_max A8 2 Mfr_Tambient_min A9 2 User_data_00 B0 48 W User memory space User_data_01 B1 48 W User memory space Read_mfr_revision D5 4 R Fan_duty_cycle D6 1 W Duty_cycle in % Fan_speed D7 1 W Control in duty cycle Vprog_ext D8 2 W Notes: Settings and read backs above support the 12Vdc main output. There are no adjustments or read backs of the standby output. Failure of the standby output is reported by the STATUS_MFR_SPECIFIC register. The code does not check the validity of, or whether the data being changed is within the expected boundary. The user is responsible to make sure that data placed in the registers is within the monitored range.
