BEP 275A Cont Motorized Dual Operation VSS (Voltage Sensitive Switch) – Deutsch Connector

275A Cont Motorized Dual Operation VSS (Voltage Sensitive Switch) – Deutsch Connector

These Voltage Sensitive Switches (VSS) automatically sense connected battery bank voltages and provide 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. 

Features:

• Deutsch Connector
• Dual battery sensing
• Manual override option
• Designed and constructed for longevity in the marine environment with tinned copper conductors, stainless steel nuts, and high temperature, fiber reinforced plastics

Features (Engine Run Sensing):

VSS will engage when the voltage on either start or house battery reaches 13.7 volts. If the combined battery voltage drops below 13.0 volts and the engine is not running, after 5 seconds the contacts will open and stay open until the start or house battery voltage exceeds 13.7 volts. If the combined battery voltage drops below 12.2 volts and the engine is running, after 5 minutes the contacts will open and stay open until the start or house battery voltage exceeds 13.7 volts. If voltage drops below 13 volts and stays above 12.2 volts on either start or house battery while engine is running, the VSS will stay engaged. 

Features (Remote Emergency Parallel Function):

• The 701-MDVS-D can be operated through a momentary button on the dash which will parallel the batteries for a present time of 10 minutes Once this 10 minutes has passed, if the voltage is up high enough for the voltage sensitive switch to operate, it will stay engaged. If not, it will disengage
• The advantages of using a high current VSS is that it will cover your dual battery charging requirements and emergency parallel operation in one unit
