The total load on the ISOLATED outlets should not exceed 350VA continuous. A load up to
500VA may be powered for 5 minutes maximum if followed by an off period of 5 minutes or
longer for cooling. Avoid using the ISOPACK in a confined area, since this could allow heat
build up to accumulate.
The total load of the DIRECT outlets should not exceed 500VA, continuous or intermittent.
However, both the DIRECT and ISOLATED outputs can be operated simultaneously at up to
full rated load capacity.
Repeat Step 1 of the previous procedure.
Connect the equipment to be powered to one of the ISOLATED outlets. The equipment may
be transformerless or transformer powered.
Select the desired voltage with the
VOLTAGE
The two 3 position switches are
connected in a matrix arrangement
as shown on the front panel of the
ISOPACK, and in Fig. 2.
matrix provides nine possible
combinations, each producing a
different output voltage.
example, if both switches are in
the center position, a 115 volt
output results. With the “ROW”
switch selecting the top row and
the “COLUMN” switch selecting
the left column, a 110 volt output
results, etc.
Repeat Steps 4 thru 9 of the previous procedure (for tranformer powered equipment, Steps 4
thru 7 are not applicable).
To vary the output voltage, change the combination of VOLTAGE SELECT switch positions
to obtain each desired value. For maximum switch life, it is good practice to turn OFF the
POWER switch before changing the VOLTAGE SELECT switches.
The voltages shown on the matrix (Fig. 2) are approximate, depending upon the load and the
input voltage’s variance from 120 volts. To determine the specific voltage, connect a precision
Multimeter to measure the AC voltage at the ISOLATED output.
