QUICK CONNECT INSTRUCTIONS
A guide for customer checkout of a PowerCassette for prototyping
Single module
: Using either a mating connector with
wires or Unipower’s PCB single interface board,
make the appropriate connections for Input Power
and Output Power, referring to the Connection Chart
shown below. Pay particular attention to the pin des-
ignations for the input. Also assure that the chassis
ground connection is tied to the appropriate safety
ground when using either AC or DC input.
Ensure
that pin 27 and pin 22 are connected together
so
that the power supply will be enabled when the Input
Power is applied. This is already connected on the
UNIPOWER PCB Interface Board but will need to
be connected if using a wired mating connector. If
additional details about the signals and/or connections
are needed, please refer to the Operating Manual for
the PCHS/TPCHS Series. For testing a single module,
it is not necessary to connect to the three current share
signals. It is recommended to connect the appropriate
remote sense lines to the corresponding outputs. This
is done via zero-ohm links on the single interface
board. Be sure to observe polarity. Note that V1, V2,
and V3 all share the same electrical return line, and
all three are ‘positive’ outputs. In order to get the best
load regulation and minimize cross-talk between the
outputs, it is suggested that the return lines to each of
the loads be connected such that the different outputs
are returned to separate returns at the power supply.
Note that V4 and V5 have the option of being either
positive or negative polarity, as determined by the
module’s model number.
