Dual Operation VSS (Voltage Sensitive Switch) and Emergency Parallel

These Voltage Sensitive Switches automatically sense connected battery bank voltages and provide optimal, effi cient 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 off ering 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, fi ber reinforced plastics.

• The units are ignition protected, provide On/Off switching operation, and may be recessed or surface mounted.
• Dual battery sensing
• 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 up high enough, the voltage sensitive switch will stay engaged. If not, it will disengage.

720-MDVSO benefits

• Dual 12V/24V operation (both banks must be same voltage)
• Low power consumption (<6mA)
• Lowered cut in voltage (13.3V/26.6V) suits low output alternators and high temperature environments

720-MDO-EP: Emergency Parallel Only

• 10 minute remotely activated emergency parallel function (no voltage sensitive function)
• 12V/24V operation (both banks must be same voltage)
