E6198B Switch/Load Unit User Manual 5-57
Note that the main power bus as well as each individual channel
bus is rated for 30 Amps continuous. Thus you can run 30 Amps
per channel for all 8 channels only if they are wired in a bridge
configuration or the current through the power supply bus
(PSbus) does not exceed 30Amps.
Local / Remote Sensing
Switch S1 allows the external power supply remote sensing to
be either local (P100/P200) or remote (through P2 to UUT).
Refer to
Figure 5-39 .
Selecting a Load Fuse
The factory installed load fuses are ¼” x 1¼”, 30-amp slow-blow.
These fuses may be replaced by fuses with a lower value
depending on your load requirements. The Agilent E6178 was
qualified with a Bussman™ MDL-30 fuse. This fuse is unique for
its low power dissipation and very high I
2
T rating which is
required to meet the Agilent E6178 surge current specifications.
Refer to the module specifications for more information.
CAUTION
It is possible to close more than one channel at a time. The power
supply connections to the load card are rated for 30 Amps
maximum continuous and individual channels are rated at 30 Amps
continuous. Do not exceed these specifications.
CAUTION
To maintain Agilent E6178 safety and reliability, replace fuse with
Bussman type MDL-30 fuse only.
