Output Voltage Range
The output voltage range is configurable between +50V and +/‐140V and the load can be either grounded
or floating. For peak‐to‐peak voltages less than 140V, the grounded load configuration is recommended
since this provides greater current. The floating load configuration is required for the +/‐100V and +/‐140V
ranges. The desired configuration should be specified at the time of ordering.
4.1 Ground load configurations
In the grounded load configurations, the actuator connections are illustrated below. The negative output is
internally grounded.
The desired output voltage range can be selected from the following table.
Three wire bender actuators can be driven using the following connection diagram. The HV+ and HV‐ bias
voltages are the minimum and maximum voltages listed in the table above and are accessible on the
output connector.
