Description
The 4130 is a self contained AC powered Bridge Excitation
Supply. The device consists of a low interwinding capacitance
AC transformer and a high stability adjustable linear regulator
designed specifically for driving transducer bridges. The
bridge supply is trimpot adjustable from 4 to 15 Volts output
and capable of supplying 0 to 150 mA in output current. This
excitation source features very low noise and state of the art
regulation. AC input requirements are 105-125 VAC at 60 Hz.
100, 220, 230, VAC Inputs are also available. Specify by
adding to Model Number, i.e. 4130-230.
