Overcurrent Protection
The power supply provides electronic overcurrent
protection for each of the 3 outputs. If the maximum
current rating is exceeded, the voltage will collapse to
a low value.
It will remain in that state until the load is either removed or reduced. A current overload (including a
short circuit condition) will not cause the fuse to open.
This power supply does not comply with FCC requirements in non-industrial applications for
conducted EMI on AC power lines.
Dual Rack Operation
A single power supply can provide power for two
racks under the following conditions:
Only 5 volt power is required in the second rack,
and the total power required by both racks is within the capability of the supply.
The current drawn by the second rack is less than
5.2 amperes.
The two racks must be mounted in close proximity
as limited by the available 3-foot connecting cableThe connecting cable used for dual rack operation is
listed in Table 1, Ordering Information. This cable
carries the +5 volts power bus as well as the power
sequencing signals. It uses a 9-pin D-type connector
which connects directly to the backplane through an
opening in the rack frame. Note that the cable carries
power and power sequencing signals only. Inter-rack
communication and bus interface modules must be
provided separately. See the applicable Programmable
Controller Installation Manual. for application information.Timing Diagram
The timing diagram below shows the relationship of the ac
input power to the dc outputs and to the two system signals generated by the power supply: ACFAIL and
SYSRESET. The 5VSTBY output may be used for user
battery backup schemes as shown.
On application of power, the ACFAIL signal goes false
soon after the 5 volt bus is within specification. The system is held in the Reset state by SYSRESET for at least
