Merlin Power M-Power VSR 12V 140A

Item: MER-04-4102
MPN: MER-04-4102
The Merlin M-Power VSR 12V 140A OEM provides automatic fit and forget split charging for lighter duty and leisure split charge applications.
Product Description
The VSR sits between two batteries. When it senses that either battery is being charged (and voltages are high enough) the unit will activate and allow power to flow between the batteries. Power will know which way to flow automatically and over-charging between different sized batteries cannot occur. VSRs introduce no losses into the charging system and smart-electronics prevent relay chatter when charging and using power from the auxiliary battery at the same time.The M-Power VSR can be used as a voltage sensitive switch if the input is wired to a battery and the output directly to a load. That load will then only receive power when the battery is being charged or is healthy enough to provide power; useful for running DC appliances that should only be used when engines are running.
