ErosTek ET-312

The ErosTek ET-312 is a pre-built e-stim driver, with two electrically isolated stimulation channels. The unit supports linking the two channels together in order to form a 'virtual' "third phase".

 * LCD character display
 * 3 knobs
 * Channel A intensity
 * Channel B intensity
 * Master parameter change
 * 4 push-buttons
 * 2 to select option
 * 1 to cancel the selection

 * 1 12V DC power input
 * 5 3.5mm jacks
 * Channel A electrode (mono plug)
