SECTION 2 - TECHNICAL DESCRIPTION
Transient Load Response
The 41-752 has been designed to provide a very fast recovery from transient loads. However, if the load has an
excessively large capacitive component then the need to charge this capacitance can limit the response time. The
power supply includes an internal 22µF load.
Cooling and Chassis Considerations
The 41-752 can dissipate high internal powers and use high backplane currents. When using many 41-752 in a
chassis users should:
Ensure the chassis has an adequate PSU source under all anticipated load conditions. The data sheet indicates
the backplane current requirements for each module under the highest rated load conditions (all channels).
The current demand for each voltage can be deduced from the number of modules fitted to the chassis.
If the chassis supports speed controlled fans it is recommended that the speed of the cooling fans is set to
maximum rather than left under automatic control. Information on how to set the speed control (if present)
should be in the manual.
Users should ensure that when rack mounting or bench mounting adequate ventilation space is allowed.
Users should follow the chassis vendor recommendations.
Pickering Interfaces strongly recommends the use of 60-103 (LXI) or 40-923 (PXI) chassis for applications requiring
large numbers of 41-752 modules. These chassis have adequate PSU and cooling capacity to be fully populated by
41-752 modules and are the chassis that Pickering Interfaces has tested the modules in. The chassis should be set
to maximum fan speed, and if desk mounted, the front feet should be raised to allow maximum air flow.
