18 PDUS210-FLEX Operation
The PDUS210-FLEX is identical to the standard PDUS210 except that it requires an external
transformer connected between the amplifier and transducer using the supplied cable. This allows
the user to switch between different output voltage ranges by changing the external transformer.
The PDUS210-FLEX must be purchased with at least one external transformer. The available part
numbers and specifications are listed in PDUS210-FLEX Specifications.

To operate the PDUS210-FLEX, the instructions are identical to the standard PDUS210 except for the
following steps that must be completed first, or when changing the transformer:
1. Disconnect the amplifier from power and connect the desired transformer, e.g. TX210-800
2. Connect the PDUS210-FLEX output to the transformer input, using the supplied cable
3. Read the turns-ratio (N) from the transformer, or specifications table, and enter this into the
textbox in the desktop software labelled 'Turns Ratio'.
4. Check that the maximum and minimum frequency settings are appropriate for the
transformer.
5. In the desktop software, press the 'Save on Device' button. This step is optional but will retain
