BEP 275A Cont Motorized Dual Operation VSS (Voltage Sensitive Switch) - Deutsch Connector [701-MDVS-D]

The BEP 275A motorized dual - operation Voltage Sensitive Switch (VSS) with a Deutsch Connector is a great solution for battery management. It automatically detects the voltage of the connected battery banks and efficiently charges the second bank. This VSS can combine or isolate independent battery banks according to the charging source like an engine alternator or battery charger. It also offers a remotely activated, high - current emergency parallel connection. Key features include a Deutsch Connector, dual battery sensing, and a manual override option. It's built for long - lasting use in marine settings with tinned copper conductors, stainless steel nuts, and high - temperature fiber - reinforced plastics. The VSS engages when the start or house battery voltage hits 13.7 volts. It has specific rules for when the voltage drops, ensuring proper battery management. The 701 - MDVS - D can be controlled via a dash button for a 10 - minute emergency parallel function. With continuous, intermittent, and cranking ratings of 275A, 455A, and 1250A DC respectively, and a voltage rating of 9.5 - 32 volts, it's a versatile and reliable choice.

Using this BEP 275A Voltage Sensitive Switch is easy. First, make sure to connect it to your battery banks correctly following the wiring diagram. The switch will automatically sense the battery voltage and manage the charging of the second bank. If you need to manually override, use the manual override option. When starting the engine, the VSS will engage when the battery voltage reaches 13.7 volts. Be aware of the voltage drop rules. If the combined battery voltage drops below 13.0 volts and the engine is off, the contacts will open after 5 seconds. If it drops below 12.2 volts while the engine is running, the contacts will open after 5 minutes. For the remote emergency parallel function, press the momentary button on the dash. The batteries will be paralleled for 10 minutes. After that, it depends on the voltage. Maintenance is straightforward. Keep it clean and dry, especially in the marine environment. Check the tinned copper conductors, stainless steel nuts, and fiber - reinforced plastics regularly for any signs of wear or damage. Make sure the Deutsch Connector is properly connected at all times.
