Overvoltage Protection
An electronic shutdown circuit protects against voltages exceeding 6.2 volts. A back-up voltage clamp is
provided to protect against sustained overvoltage
conditions due to either external influences or internal
faults. Overvoltage due to internal faults may cause
the fuse to open. For short term overvoltage conditions, normal operation will resume when the cause is
removed.An electronic current limit is provided on each of the
three outputs. An overload on any output will cause
the voltage to collapse and may cause the other output voltages to collapse.
Normal operation will resume after removal of the
overload. Some component cooling time may be required before normal operation resumes.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 cable.
The 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.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
200 milliseconds after 5 volt power is available (during
this time, outputs are forced off).
