LOAD CONNECTION, LOCAL ERROR SENSING

The DC OUTPUT connector is located on the back of chassis, and is designated A6-J2 in the
schematic. Table 2-4 and Figure 2-2 provide the function and location of DC OUTPUT connector
pins.

NOTE: The sense terminals MUST be configured for either local sensing (as follows) or

remote  sensing  (see  PAR.  2.6.5)  for  the  MAT  Power  Module  to  operate.  If  left
unconnected the unit will automatically isolate the load and shut down.

For  Local sensing  connect  Output  Terminal  1    to Sense Terminal  1,  and  Output  Terminal  2 to
Sense Terminal 2 at the DC Output connector (see Figure 2-5).

2.6.5

LOAD CONNECTION WITH REMOTE ERROR SENSING

The  MAT series of  Power Modules can operate  with sensing  external to the Module. Sensing
should be with a twisted wire pair to reduce noise. The sensing wires must be connected as fol-
lows: Output terminal 1 to Sense Terminal 1 and Output Terminal 2 to Sense Terminal 2, each at
the load (see Figure 2-6). Refer to Table 2-4 and Figure 2-2 for DC Output connector pin func-
tions and locations.

When the MAT Power Module is connected for remote error sensing (in the voltage mode), a sit-
uation might occur where the output capacitor C14 must be supplemented to achieve optimum
performance. If oscillations are observed at the output terminals or at the load, the load should
be decoupled with another high quality capacitor of a value equal to or greater than C14.
