ISSUE 1
The DSEA109 is an Automatic Voltage Regulator (AVR) designed to control alternator excitation voltage to
produce the desired alternator output. Adjustment is made using potentiometers. Alternatively more
comprehensive configuration is available using DSE Configuration Suite PC Software and the DSE815
interface. Additionally this provides live diagnostic facilities.
NOTE: For the full specifications and mounting details, refer to DSE Publication: 057-295 DSEA109
Operator Manual, available from www.deepseaelectronics.com.
WARNING!: LIVE PARTS exist within the AVR. When powered avoid contact with components and
terminals. Terminals remain live for up to 70 seconds after shutdown. Do not touch during this time.
Only qualified personnel, having full understanding of the application must install the product.
NOTE: A suitably located and easily reached switch or circuit breaker must be fitted and clearly
marked as the disconnecting device for the AVR.
POTENTIOMETER ADJUSTMENT
It is possible to disable the potentiometer using the DSE Configuration Suite PC Software and DSE815
Configuration Interface. This allows the system designer to restrict end user adjustment should this be required.
DIP SWITCH ADJUSTMENT
DIP switches are used to select the operating range of the AVR.
