Maximum power usage with Series 3700A cards
The Series 3700A series offers a growing family of high-density and general-purpose plug-in cards
that accommodates a broad range of signals at very competitive pricing. The Series 3700A supports
applications as diverse as design validation, accelerated stress testing, data acquisition, and
functional testing.
Plug-in cards are capable of switching many relays at once, which can take a substantial amount of
system power. There is a limited amount of system power available for switching relays. Therefore,
use care in order that Series 3700A maximum available power is not exceeded. The maximum power
available is limited on a per-bank basis as follows:
Bank 1
Bank 2
Slot 1
Slot 4
Slot 2
Slot 5
Slot 3
Slot 6
12300 mW (max)
12300 mW (max)
Based on the previous table, the total power available for slots 1, 2, and 3 is 12,300 mW (12.3 W).
Similarly, the total power available for slots 4, 5, and 6 is 12.3 W. Attempting to exceed these power
levels results in the system performing as many of the operations as possible until these power limits
are reached. An error message is then created and the remaining operations are not performed.
NOTE
There is also a maximum slot power limit of 10,500 mW. However, the maximum is rarely a
consideration.
