West Mountain Radio ISOpwr+ (Plus) Auxiliary Battery Isolator

• Isolates and charges a 12 Volt auxiliary battery to run mobile radio and other 12 Volt portable equipment.
• Ideal for mobile radio command stations for ARES, RACES, FEMA, and for a VHF/UHF Contest Rovers, moderately powered ham equipment, a re-charging station for electric model airplanes, boats and cars, and for RV's and campers.
• Charging from vehicle starts when the car is running and the alternator is maintaining the car battery over 13.5 volts.
• Charging from vehicle stops when the alternator is off and the car's battery has fallen below 12.6 volts.
• All solid state. FET switch. No relays. Handles up to 40 amperes. Input fuse 40A.
• Works safely with all types of 12-volt lead-acid batteries, Flooded Lead Acid, Gelled & AGM.
• May be used without a battery to automatically turn a radio on whenever the car is running. The radio will turn off with a small delay after the car is stopped.
