The AIMS Power 10 Amp 48V to 12V DC-DC Step Down Converter changes 44 to 58 Vdc battery power into a regulated 12.5 to 13.5 Vdc output. It's rated 10A continuous at 25°C (77°F) with a 12A maximum, and AIMS lists conversion efficiency above 91%.
It's the middle size in AIMS's 48V to 12V lineup, for boats, golf carts, lights and other automotive, mobile and off-grid systems that run on 48V but still need a 12V circuit. The aluminum case measures 4.41 x 3.39 x 2.2 inches and weighs 0.71 lbs.
Input from 44 to 58 Vdc comes out as 12.5 to 13.5 Vdc, so you can run 12V electronics and accessories from a 48V battery bank.
The converter shuts down if input falls to 40 ± 2 V or climbs to 59 ± 1 V. That protects the converter and your load when the battery is too low or too high.
A 5A input fuse handles input over current and polarity protection. On the output side you get short circuit protection, over current protection at 12A and a TVS diode for over voltage. Over temperature protection is set at 65 ± 5°C (149 ± 5°F).
AIMS lists heat dissipation for the 10 amp model as thermal and load controlled, and the manual's rear panel drawing for the 10A and 20A models shows a fan.
The front terminal block is marked + 48V − for DC input and − 12V + for DC output. A green power LED confirms the converter is on, and the input fuse sits in a holder right below the terminals.
Golf carts. Run 12V lights and accessories from a 48V golf cart battery pack.
Boats. Supply 12V electronics from a 48V system. Mount the converter where it stays dry and away from spray and bilge.
Work vehicles and equipment. Wire it into vehicles, equipment or custom power systems that need 12V from a 48V source.
All three AIMS 48V to 12V converters use the same 44 to 58 Vdc input and 12.5 to 13.5 Vdc output. The 5 amp model is smaller with 6A max, and the 20 amp model handles 20A continuous with 24A max. The 10 amp model suits 12V loads between those two.
This converter is non-isolated, and AIMS notes a non isolated ground. If your system needs the input and output kept isolated, look at an isolated converter instead.
Add up your 12V load and make sure it stays within 10A continuous, with 12A as the maximum. AIMS says the battery source must be 48Vdc and the load 12Vdc.
AIMS lists input cable larger than 20AWG and output cable larger than 16AWG, a cable length limit of under 1m or 3 feet and 2-3.7 fork terminals. Turn your load off before connecting it. Connect the negative wire to the battery first, then the positive, and never reverse polarity.
AIMS rates the 10 amp model's conversion efficiency at more than 91%.
Yes, as long as the pack stays within the 44 to 58 Vdc input range. AIMS lists golf carts among the uses for this converter.
Pick a dry, suitable location with enough space for the wires. Don't expose it to rain, snow, spray, bilge or dust.
AIMS lists a 2-year warranty from the date of purchase.
The AIMS Power 10 Amp 48V to 12V DC-DC Step Down Converter turns your 48V battery bank into a steady 12V supply, with input shutdowns, fuse protection and output safeguards built in. If you'd like help choosing between the 5, 10 and 20 amp models, the Outbound Power team is happy to help.
