9 PDUS210-FLEX Specifications
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. For
operating instructions, please refer to PDUS210-FLEX Operation.
The PDUS210-FLEX must be purchased with at least one external transformer. The default output
configuration is electrically isolated with a bipolar voltage. Refer to Unipolar Output Voltage for other
options. The available part numbers and specifications are:
