BEP Digital Voltage Sensing Relay DVSR - 12/24V [710-140A]

The Digital Voltage Sensing Relay (DVSR) - 12/24V is a great solution for charging multiple battery banks. It allows you to charge a second battery bank from a single charging source like an alternator or battery charger. When the voltage of the charged bank rises enough, the DVSR kicks in to charge the second battery bank. When charging stops and the voltage drops, it automatically isolates the battery banks to keep engine start batteries fully charged. With digital circuitry, it offers high reliability and extremely low power consumption. It also has remote sensing circuitry that, when connected to the ignition switch, provides the same function as a single - sense VSR and zero power consumption when the engine is off. When used with a storage mode switch, it has zero standby current draw. Key features include safely charging multiple battery banks, charging engine - starting batteries first, protecting start batteries from domestic loads, isolating electronics from electrical surges, easy 3 - wire installation, no volt drop compared to diode isolators, ignition protection, surface or panel mounting, replacing previous models, auto - selecting between 12 and 24V DC, low power consumption, and an optional remote status LED output. WARNING: This product can expose you to chemicals like di(2 - ethylhexyl)phthalate (dehp) known to cause cancer, birth defects or other reproductive harm in California.

Using this Digital Voltage Sensing Relay (DVSR) is easy. First, connect it to your charging source, like an alternator or battery charger, and your battery banks using the simple 3 - wire connection. Make sure to keep the alternator wiring intact. The DVSR will automatically start charging the second battery bank when the voltage of the first one rises enough. When the charging stops and the voltage drops, it will isolate the battery banks to protect your engine start battery. Regarding maintenance, there's not much to do. Just check the connections regularly to make sure they are tight and free of corrosion. Keep it away from excessive heat and moisture. Also, be aware that this product contains chemicals that can be harmful. If you're in California, check P65Warnings.ca.gov for more information.
