Dual Operation VSS Switch HD Optic - 12/24V - 500A
This Voltage Sensitive Switch (VSS) automatically senses connected battery bank voltage and provides optimal, efficient charging of the second bank. The VSS allows for independent battery banks to be combined or isolated based on the presence of a charging source (such as an engine alternator or battery charger), while also offering remotely activated, high current, emergency parallel connection.
Designed and constructed for longevity in the marine environment with tinned copper conductors, stainless steel nuts, and high temperature, fibre reinforced plastics. The units are ignition protected, provide On/Off switching operation, and may be recessed or surface mounted.
The remote emergency parallel function can be operated through a momentary button on the dash which will parallel the batteries for 10 minutes. Once this 10 minutes has passed, if the voltage is high enough, the voltage sensitive switch will stay engaged. If not, it will disengage.
Features:
- Dual battery sensing
- Manual override option
- Dual 12/24 volt operation (both banks must be same voltage)
- Low power consumption (<6mA)
- Lowered cut in voltage (13.3/26.6V) suits low output alternators and high temperature environments
Technical Specifications:
- Volts - 12/24V
- Rating - 500A
- Dimensions (L x W x H) - 4" x 4" x 4.3"
In the Box:
- Parallel Switch
- Instruction manual

The BEP Marine Dual Operation VSS Switch HD Optic automatically senses battery bank voltage to help charge a second battery bank efficiently. Designed for marine electrical systems, it combines or isolates independent battery banks based on the presence of a charging source, such as an engine alternator or battery charger, while providing a remotely activated high-current emergency parallel connection.
Built for marine use, this voltage sensitive switch features tinned copper conductors, stainless steel nuts, and high-temperature, fiber-reinforced plastics. It offers ignition-protected On/Off switching and can be recessed or surface mounted. The remote emergency parallel function can be activated with a momentary dash button, paralleling the batteries for 10 minutes. After that period, the switch remains engaged if voltage is high enough and disengages if it is not.
Key Features
- Dual battery sensing helps manage independent battery banks.
- Manual override provides a remotely activated emergency parallel function.
- Operates with 12V or 24V systems when both battery banks use the same voltage.
- Low power consumption of less than 6mA.
- Lowered cut-in voltage of 13.3V/26.6V suits low-output alternators and high-temperature environments.
- 500A rating for high-current battery bank connection.
