Product Highlights
Design Elements
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
of 250W for +3.3VDC, +5VDC, and 12VDC
with independent output regulation. The
low-cost unit meets the electrical and
mechanical requirements of the PICMG*
specification for CompactPCI systems. It
utilizes a PICMG 2.11-compliant 47-pin
power connector to provide efficient,
effective connectivity, and is UL, CSA, TUV
and CE certified.

Operation
The ZT 6303 250W power supply utilizes
switching technology to achieve its small
size and large power output. An EMI-filtered
universal input automatically accepts AC
input voltages from 90 to 264V. Optionally,
two or more power supplies can be used to
implement an N+1, load sharing, fault
tolerant system.
Load Sharing and N+1 Redundancy
Two power supplies can share the same
output load. These two supplies each
supply approximately 50 percent of the total
output power during normal operation,
although either is capable of powering the
entire system in the event that the other
should fail (with a 250W load). This feature
increases overall system reliability by
Design Elements (continued)
sharing the load responsibilities. Additional power
supplies may be used to implement true N+1 load
sharing (i.e., a 500W system requires two power
supplies, plus a third for redundancy).
Hot Swap
The power supplies can be inserted or removed from the
system without disturbing operation or reducing the
reliability of any associated devices.
Fault Tolerant
A failed power supply will not disturb the operation of the
system if a redundant power supply is operating in the
system.
Power Factor Correction
Power factor correction is utilized on the Intel
ZT 6303
to conserve power and decrease energy costs. The
power factor correction circuitry also achieves reduced
power line harmonics.
Status LEDs
Two status LED indicators are visible from the front of the
power supply. The green "INPUT OK" LED indicates that
the input voltage is present. The red "FAULT" LED
indicates a failed power supply or input source.
Remote Sense
Remote sense on the +3.3V, +5V, and +12V power
supply outputs compensate for connector,
backplane, and wiring voltage drops.
Inhibit/Enable Inputs
The Inhibit (INH#) input signal on the rear connector
will turn off the outputs when connected to logic
ground. The Enable (EN#) input must be connected
to logic ground for proper operation of the supply;
this signal input is used as the last-mate/first-break
contact for hot swap operation. Both signals are
open-drain TTL compatible inputs.
System Notification
Two fault outputs are available on the rear connector
for system notification. One output (DEG#) is an
open-drain, low-true signal that indicates the internal
temperature is approaching the maximum internal
operating temperature. If action does not reverse the
internal temperature rise, the supply will shut off the
outputs. The second output (FAL#) is an open-drain,
low-true signal that indicates if any of the outputs
have failed and/or the input voltage has dropped to
less than 85VAC.
