As shown in
loads are through P100 and P200 to PWR1 and PWR2 (J41)
respectively. You must wire the power supply connectors to the
individual channel connectors CH1 through CH8 (J101, J103,
J105, and J107). Use at least a 14 AWG PTFE insulated or 12
AWG vinyl insulated wire to carry 30 Amperes.
<Blue>Figure shows one possible power supply configuration.
In this configuration, Channel 1 is configured for a single load
connected to V+. Load 8 would be a short to provide a path
return. Channels 2 and 3 are connected as a bridge load; a load
that is "floating" with respect to the power system.
Other configurations are possible. For example, the negative
terminals of two external power supplies could be connected
together at the UUT and the positive terminals could be
connected to P100 and P200 (respectively) and distributed to
the individual channels. This would provide two simultaneous
power supply connections to the UUT or multiple UUTs.
