The BEP 720-MDVSO is a dual operation voltage sensitive switch (VSS) for 12V/24V systems (both battery banks must be the same voltage), providing dual battery sensing and automatic combine/isolate control based on the presence of a charging source such as an alternator or battery charger. It also includes a remote emergency parallel function operated by a momentary dash button to parallel batteries for 10 minutes, with manual override, low power consumption (<6mA), and a 500A rating, designed for long-term marine use with ignition-protected construction.

BEP 720-MDVSO – Dual Operation VSS (Voltage Sensitive Switch), 12/24V, 500A Rating, with Emergency Parallel
The BEP 720-MDVSO is a dual operation VSS (Voltage Sensitive Switch) designed to automatically sense connected battery bank voltages and provide optimal, efficient charging of a second bank. The VSS allows 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 a remotely activated, high-current emergency parallel connection.
Designed for longevity in the marine environment, the switch uses tinned copper conductors, stainless steel nuts, and high temperature, fiber reinforced plastics. The unit is ignition protected, provides On/Off switching operation, and may be recessed or surface mounted.
Key Features
- Dual battery sensing
- Combines or isolates independent battery banks based on charging source presence
- Remote emergency parallel function operated via a momentary dash button
- Manual override option
- Ignition protected
- On/Off switching operation
- Recessed or surface mount installation
Emergency Parallel Function
- Remotely activated emergency parallel function operates for 10 minutes
- After 10 minutes, if voltage is high enough the voltage sensitive switch will stay engaged
- If voltage is not high enough, it will disengage
720-MDVSO Benefits
- Dual 12V/24V operation (both banks must be the same voltage)
- Low power consumption (<6mA)
- Lowered cut-in voltage: 13.3V / 26.6V
