This is a 13.8 volt battery back-up system for powering your radio station, “go box”, or RV. It can output up to 40 amperes from either the power supply or the battery. The radio, or other equipment connects to the or-gate output. One input comes from the power supply, the other input is connected to a 12 volt battery. The higher voltage of the power supply passes through to the output. But when ac power is lost and the power supply goes dead, the gate switches to the battery, instantaneously. When the power comes back on again, the gate switches back to the power supply, and the built in 2 ampere constant current charger rapidly restores the battery to full charge. Ideal for use with Bioenno Lithium-Ferrous-Phosphate batteries as well as sealed lead-acid batteries. The DC 40+ is solidly made on a heatsink and connections are Powerpoles.
