Deep Sea Electronics DSEA109 Installation Instructions
Document Number: 053-245
Issue: 1
Product Overview
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. This also provides live diagnostic facilities.
Important Information
- NOTE: For 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.
DIP Switch 1

Typical Wiring Diagram Description
The wiring diagram illustrates the connections for the DSEA109 Automatic Voltage Regulator (AVR) to an AC alternator. Key components and connections are detailed below:
- Alternator Connections: The diagram shows connections from the AC Alternator, including the PMG (Permanent Magnet Generator) output, excitor winding, and main AC outputs (U, V, W). It also shows connections for F+ (Field Positive), F- (Field Negative), S1, and S2, which are related to the excitor winding and droop CT.
- Power Input: The AVR receives power input, indicated as 100V TO 270V, likely for its internal operation or control circuits.
- AVR Internal Components: The diagram depicts internal elements of the AVR, including SCR (Silicon Controlled Rectifier), CAN (Controller Area Network) interface, LED INDICATOR, and CONFIGURATION INTERFACE CONNECTION.
- DIP Switches: A set of four DIP switches (1, 2, 3, 4) are shown, used for configuration. Adjacent to these are labels for control functions: INTEGRAL, PROPORTIONAL, UNDER FREQUENCY ROLL OFF, DROOP, and VOLTAGE SET POINT.
- External Inputs: The AVR accepts external AC voltage bias inputs, ranging from 0 Ω TO 5 kΩ and -10 V TO 10 V.
- Droop CT: A connection for a Droop Current Transformer (CT) is shown, with a 1A OR 5A SECONDARY rating.
- Fuses: 15 AMP ANTI-SURGE FUSES are incorporated in the wiring to protect the system.
- Output Terminals: The AVR outputs are connected to the alternator's excitor winding and potentially other control points. Terminals are labeled L1 (R), L2 (S), L3 (T), and N (Neutral).
- Configuration Interface: A connection point for a configuration interface is shown, labeled '15V TO 600V', suggesting it's for connecting to the DSE815 interface or similar.
