14-SLOT PXI CHASSIS 40-914
POWER SUPPLY
The 40-914 uses two hot swappable modular power supplies that have easy access from the front panel. Standard
versions are operated from the supply to the chassis which can be in the range of 90V to 260V AC. Optional power
supplies are DC operated from 36V to 72V (Option 1) or 18V to 36V (Option 2). The power supply modules provide
+5V, +3.3V, +12V and -12V DC to the PXI backplane.
When two power supplies are installed (standard configuration), either one is capable of supplying the entire system
power should the other one fail (providing the total PXI module load does not exceed the power capability of a single
power supply module). Users may insert or remove a redundant power supply from the system without interrupting
the system operation (provided the backplane load can be supplied from one power supply module). However, for
systems where the chassis is fully populated, it is recommended that the system is powered down prior to changing
a power supply.
In the event of failure, replacement power supply modules are available as spare parts from Pickering with the order
code: 44-910-003.
