xppower.com 4 10011388 revision B Characteristic Notes & Conditions Signals & Control Remote Sense Compensates for 0.5 V total voltage drop AC OK AC OK is an opto isolated transistor, referenced to logic ground, providing a minimum of 3 ms warning of loss of output regulation. The signal is fully isolated and the collector and emitter must be connected externally. The transistor is normally on when AC is healthy. See fig. 6 & 16. DC OK DC OK is an opto isolated transistor, referenced to logic ground, providing warning of loss of output. The signal is fully isolated and the collector and emitter must be connected externally. The transistor is normally on when output DC is healthy. See fig. 7 & 16. Inhibit Floating isolated optocoupler diode referenced to logic ground powered diode inhibits the supply. See fig. 8 & 18. Enable Enable pin should be pulled low with reference to V1 ground to switch the output on. Enable pin is shorter and mates last when the unit is plugged into a mating connector. The Enable pin location differs between 12/24V & 48/56V models. See fig. 13. Fault Fault is an opto isolated transistor, referenced to logic ground, providing warning of power fail, DC fail or fan fault. The signal is fully isolated and the collector and emitter must be connected externally. The transistor is normally on when there is no fault. See fig. 9. Pwr ID The power ID pin B2 can be used to detect the presence of the unit when fitted in a rack. See fig. 14. Current Share Connecting pins A1 and C1 of like voltage units (8 maximum) will force the current to share between the outputs. Units share current within 10% of each other at full load. See fig. 12 & 15. V Program The voltage program function allows ±10% remote adjustment of V1 via 0-5V signal. See fig. 10. Current Monitor Enables the monitoring of the supplied current from V1 output. See fig. 11. I The I2C PMBus compatible interface can be used for monitoring the unit output voltage, current, internal temperature and run time. It can also be utilized to turn the unit on and off, detect faults along with identification of the unit model number and serial number.

CAUTION SINGLE OUTPUT RACK: Use all rectifier units with the same rated output voltage. DUAL OUTPUT RACK: Make sure that each output use rectifiers with the same output voltage rating. Use double hole, UL Listed lugs for all DC connections to prevent lug rotation and inadvertent contact with other circuits. Th e maximum current draw per side is 200 A. Reference table 13 to determine minimum wire sizes for all dc connections. In practice, loop voltage drop considerations will u sually dictate larger than minimum safe wire size. Custom output buss bars should be considered for over 125A per side. T able 14 shows recommended torque settings for all mechanical and electrical connections according to screw or nut size. XP does not recommend shipping the rack with the power modules installed. Power modules should be shipped in separate boxes.

Interface Levels (Physical Layer) The interface levels are open drain (with pull-ups installed inside the rectifier on the SDA and SCL lines). The address bits A 0, 1, and 2 are pulled up internally to +5 VDC through 10 KOhm resistors so that in order to select the lower three bits of address information, the address bit needs to be left open (a "1") or grounded (a "0"). All ground references for the PMBus interface are to pin 15 (Signal Ground) on the I/O connector. System level bypassing of SCL and SDA lines may be required in order to reduce bus noise levels. We recommend a bus capacitance of 220 pF on the host system (other capacitance may work and is more system layout dependent than any thing else). We recommend a maximum data rate of 100 Kbps. Address Byte The address for the PMBus interface is set by a combination of fixed device type bits (A6 – A3) and floating address bits (A2 – A0). The device address byte definition is shown below: PMBus Interface Bit 7 6 5 4 3 2 1 0 Level H L H H X X X X Address Bits A6 A5 A4 A3 A2 A1 A0 R/W X = H or L

xppower.com The floating address bits are connected to the back-plane interface and pulled high via 10 kOhm resistors. This allows for up to eight power supplies to be addressed individually by leaving the address bits open (high) or grounded (low). The table below shows a ll of the PMBus address combinations: The addressing is similar to the Group Command Protocol without PEC as mentioned in the PMBus standard. Addresses are continually read at a once per five second rate . Changing an address once the unit is powered up will affect the unit's address. Addresses will not be latched. Supported PMBus Protocols The PMBus slave interface supports Read/Write Byte, Read/Write Word, and Read/Write Block protocols as defined in the PMBus specification. The figures below are from the PMBus specification and are repeated here for convenience. A write to a read-onl y command is ignored.

xppower.com Block Protocols: Data Registers (Standard Data Responses) The data registers inside the unit are divided into two types: 1) read only data and 2) R/W data. Therefore, the R/W bit in the address byte needs to be set high in order to read the status bytes, or set low in order to write data into the status bytes. The first byte of a Write Byte/Word access is the command code. The next one or two bytes are the data to be written. In this example, the master asserts the slave device address followed by the write bit. The device acknowledges, and then the master delivers the command code. The slave again acknowledges before the master sends the data byte or word (low byte first). The sla ve acknowledges each byte, and the entire transaction is finished with a STOP condition. Reading data is slightly more complicated than writing data. First the host must write a command to the slave device. Then the host must follow that command with a repeated START condition to denote a read from that device’s address. The slave then returns on e or two bytes of data. Note that there is no STOP condition before the repeated START condition, and that a NACK signifies the end of the read transfe r.

xppower.com Data Registers (Inventory Data Responses) PMBus Block Write and Block Read commands are used to write and retrieve inventory information. The Block Write and Read commands require that the first data byte is the number of data bytes to follow (Byte Count). The Block Write begins with a slave address and a write condition. After the command code, the host issues a byte count which describes how many more bytes will follow in the message. If a slave has 20 bytes to send, the byte count field will have the v alue 20 (14h), followed by the 20 bytes of data. The byte count does not include the PEC byte. The byte count may not be zero. A Block Read or Write is allowed to transfer a maximum of 32 data bytes. A Block Read differs from a block write in that the repeated START condition exists to satisfy the requirement for a change in the transfer direction. A NACK immediately preceding the STOP condition signifies the end of the read transfer.

xppower.com (OPERATION) On / Off Command 01h The OPERATION command is used to turn the unit on and off in conjunction with the input from the Enable pin. The unit stays in the commanded operating mode until a subsequent OPERATION command instructs the device to change to another mode. At power up the rectifier will turn the unit on and keep it on until told to do otherwise. The contents of this register can be written and read to, but will not be maintained through a power cycle (all reset to normal operation when power is cycled).

The status data registers are defined as shown below:

xppower.com Bits Description Value Meaning 7:6 Response to OC Trip

00 Do nothing, continue to supply output voltage until hardware OC trip point

activates, (Default setting).

01 Do nothing, continue to supply output voltage until hardware OC trip point

activates, (Default setting).

10 Do nothing, continue to supply output voltage until hardware OC trip point

activates, (Default setting).

11 The power supply shuts down and responds as programmed by the Retry

setting in bits 5:3.5:3 Retry Setting 000 A zero value for the retry setting means that the unit does not attempt to restart. The output remains disabled until the fault is cleared as mentioned in the Status/Control section. 001-110 The power supply attempts to restart the number of times set by these bits. The minimum number i ≤1 (001) and the maximum number is 6 (110). The on time for the retries is set at 10 ms. If the unit turns on during the retry the fault is cleared and the unit operation normally. Once the number of retries is reached the unit shuts down until the fault is cleared as mentioned in the Status/Control Section. 111 The power supply attempts to restart continuously without limitation until it is commanded to turn off via the On/Off command (01h register) or AC power is cycled. 2:0 Delay Time 000-111 Not implemented. (IOUT_OC_FAULT_LIMIT) Current Limit Set Point 46h The IOUT_OC_FAULT_LIMIT command sets the value of the output current, in percents, that causes the over-current detector to indicate an over-current fault condition. The two data bytes are HEX respresentation of the decimal in percentage, ie. 120% current limit, DEC2HEX (120d) = 0078h. Once an over-current occurred, the power supply will go to hiccup mode, OFF-time = 10 ms, On-time = 100 ms. (IOUT_OC_FAULT_RESPONSE) Current Limit Fault Response 47h The IOUT_OC_FAULT_RESPONSE command instructs the device on what action to take in response to an output over-current fault. The register function is given below: Resetting the over-current function There are two ways to get the power supply out of the over-current mode once the unit has latched off: 1. Cycle the AC input power. 2. Using the ON/OFF command from the OPERATION (01h) register. If the power supply is in continuous retry mode, the supply will turn back to normal operations if the load is decreased below the over- current fault limit setting.

If either signal is a 1, set this bit to a “1”. The relationship between X, N and the value commincation is: Y = X.2 N. Where, as described above: Y is the value being communcated, X is an 11 bit, two’s complement integer, and N is a 5 bit, two’s complement integer. To calculate the current or voltage from PMBus read out: 1. Extract N value from the PMBus read out, N is a fixed integer. The resulting 11 bits equals X*2^N 2. Solving for X. N = -4. Converting X (11 bits binary) to decimal and multiply by 2^N to derive the communicated data. 48V IOUT rectifier example max value = A3FF N = -4 (10100 first 5 bits of the word), X = 2047 (011,1111,1111 last 11 bits of the word) 1023 * 2^-4 = 63.96 A
