The CPC6314
Hot-Swap DC Power Supply, part of our Advanced Managed Platform product
offering, combines high power capacity with standards-based IPMI management
capability and a reliable, modular package to become the power supply of choice
for systems requiring DC power input. This CompactPCI® 3U x 8HP form factor
supply is ideally suited for telecommunications, industrial automation and a
variety of embedded computer applications where redundancy and hot-swap are
required.
The input voltage range is -36 to -72VDC. Four outputs are capable of providing a total of 325W for +3.3VDC, +5VDC and ?12VDC with independent output regulation. This supply implements management functions such as system control, monitoring and status reporting through an IPMI-based intelligent communications bus. The CPC6314, meets the electrical and mechanical requirements of the PICMG® specification for CompactPCI systems. It uses a 47-pin Positronic power connector to provide efficient, effective, high current DC connectivity and is UL, CSA, IEC recognized TUV CB Certificate and CE Marked.
The ZT 6303 250-Watt Hot-Swap Power Supply is available as an AC alternative.
The CPC6314 325W power supply utilizes switching technology to achieve its small size and large power output. An EMI-filtered input automatically accepts DC input voltages from -36 to -72VDC. Optionally, two or more power supplies can be used to implement an N+1 or N+N, load sharing, fault-tolerant system. An optional I2C hardware bus interface supports IPMI protocol for use in systems compliant with the PICMG 2.9 R1.0 specification.
Two or more power supplies can share the same input source. With two supplies, each provides approximately 50 percent of the total system power during normal operation, although either is capable of powering the entire system (with a 325W load) in the event that the other should fail. This feature increases overall system reliability by sharing the load responsibilities. Additional power supplies may be used to implement true N+1 load sharing (i.e., a 650W system requires two power supplies, plus a third for redundancy).
The CPC6314 power supply can be inserted or removed from a system employing a redundant power scheme without disturbing operation or reducing the reliability of any associated devices. Likewise, a failed power supply will not disturb the operation of the system if a redundant power supply is operating in the system.
Two status LED indicators are visible from the front of the power supply. The green “INPUT” LED indicates that the input voltage is present. The green “INPUT” LED blinks when the power supply outputs are inhibited. Off indicates no input power is present. The amber “FAULT” LED indicates a failed power supply or input source.
Remote sense on the +3.3V, +5V and +12V power supply outputs detects the voltages at a load remote from the power supply, compensating for connector, backplane and wiring voltage drops >0.25V.
The INH# input signal on the rear connector turns off the outputs when grounded. EN# is used in conjunction with INH# to enable the power supply after all signals make contact with the mating connector. Outputs are disabled as the EN# pin is disengaged.
The source into a grounded connection is <150mA and the open circuit input voltage shall be <+15VDC. The signal is capable of sinking >2mA and maintaining the output voltage at <0.5VDC.
Active current sharing is provided on the +3.3V, +5V and +12V power supply outputs with accuracy better than 10 percent of maximum rated load with up to eight supplies operating in parallel. Passive (droop response) current sharing is provided on the –12V output.
Two fault outputs are available on the rear connector for system notification. One output (DEG#) is an open collector/drain, low true signal that indicates the internal temperatures are within 10 (degrees) C of the thermal shutdown limit. The second output (FAL#) is an open collector/drain, low true signal that indicates when the supply has shut off the outputs due to a problem or the input voltage has been removed.
A 125 percent of nominal overvoltage condition on any of the outputs disables all outputs of the power supply. Outputs can be enabled, once the overvoltage condition is resolved, either with an IPMI command or by cycling the input power of the system.
The power supply automatically shuts down if an overtemperature event occurs. Overtemperature events causing a shutdown include a hardware-defined trip point or a trip point defined through an IPMI command. Once the supply cools down the supply restarts automatically.
These pins configure the final IPMI address for the power supply. The geographical address pins are pulled up to +5VDC via a 10KW±10 percent resistor on each signal.
The CPC6314 provides an I2C hardware bus interface that supports IPMI protocol consistent with PICMG 2.9 R1.0. The IPMI controller is an event generator and is implemented as a dynamic SDR device.
