product brief ® ™ Intel NetStructure ZT 6303 250-Watt Hot Swap AC Power Supply Product Overview ® The Intel ZT 6303 Hot Swap AC Power Supply is a highly reliable modular package designed for AC power input systems. Extra- high current density allows this unit to deliver up to 40 amperes on either the +5 or +3.3 volt outputs at 50 C. This highly dense, hot swap, redundant supply is ideally suited for telecommunications, industrial automation and a variety of embedded computer applications utilizing the CompactPCI* 3U x 8HP x 160 mm form factor. The universal input voltage range is 90 to 264VAC @ 47 to 63 Hz with remote sense and active current sharing. Four outputs are capable of providing total combined power � Inhibit (INH#) and Enable (EN#) Inputs of 250W for +3.3VDC, +5VDC, and ±12VDC (open drain, TTL compatible) with independent output regulation. The � PICMG 2.11-compliant 47-pin connector low-cost unit meets the electrical and � Fully compliant to PICMG 2.11 mechanical requirements of the PICMG* CompactPCI Specification specification for CompactPCI systems. It utilizes a PICMG 2.11-compliant 47-pin power connector to provide efficient, Design Elements effective connectivity, and is UL, CSA, TUV Operation and CE certified. The ZT 6303 250W power supply utilizes switching technology to achieve its small size and large power output.

Both signals are system if a redundant power supply is operating in the open-drain TTL compatible inputs. system. System Notification Power Factor Correction Two fault outputs are available on the rear connector ® Power factor correction is utilized on the Intel ZT 6303 for system notification. One output (DEG#) is an to conserve power and decrease energy costs. The open-drain, low-true signal that indicates the internal power factor correction circuitry also achieves reduced temperature is approaching the maximum internal power line harmonics. operating temperature. If action does not reverse the internal temperature rise, the supply will shut off the Status LEDs outputs. The second output (FAL#) is an open-drain, Two status LED indicators are visible from the front of the low-true signal that indicates if any of the outputs power supply. The green "INPUT OK" LED indicates that have failed and/or the input voltage has dropped to the input voltage is present. The red "FAULT" LED less than 85VAC. indicates a failed power supply or input source.
