The AIMS Power 5 Amp 48V to 12V DC-DC Step Down Converter Runs 12V Lights and Accessories From Your 48V Battery Bank
The AIMS Power 5 Amp 48V to 12V DC-DC Step Down Converter takes 44 to 58 Vdc from a 48V battery bank and delivers a steady 12.5 to 13.5 Vdc output. It supplies 5A continuous at 25°C (77°F), up to 6A max, and AIMS rates its conversion efficiency above 92%.
AIMS built it for boats, golf carts and lights, along with other automotive, mobile and off-grid systems that run on 48V but need 12V for electronics and accessories. At 3.62 x 3.39 x 2.2 inches and 0.57 lbs, it's more compact than AIMS's 10 and 20 amp 48V to 12V converters.
AIMS Power 5 Amp 48V to 12V DC-DC Converter Features
Steady 12V From a 48V Source
The converter accepts 44 to 58 Vdc and holds its output between 12.5 and 13.5 Vdc, so 12V devices can run from a higher voltage battery bank.
Input Protection That Watches Your Battery
Low battery shutdown at 40 ± 2 V and high battery shutdown at 59 ± 1 V keep the converter from running on unsafe input voltage. A 3A input fuse provides over current and polarity protection.
Output and Thermal Protection
The output has short circuit protection, over current protection at 6A and TVS diode over voltage protection. Over temperature protection trips at 65 ± 5°C (149 ± 5°F).
Simple Terminal Block Wiring
A four-screw terminal block on the front is marked DC input + 48V − and DC output − 12V +. A green power LED shows the unit is on, the fuse sits in a holder below the terminals, and a slotted mounting plate makes it easy to secure.
Metal Case Cooling
The 5 amp model dissipates heat through its aluminum case, which also adds durability in vehicles and equipment.
Real-World Applications
Golf carts. Run 12V lights or accessories from a 48V cart battery pack.
Boats. Power small 12V electronics on a 48V system, with the converter mounted in a dry spot away from spray and bilge.
Lighting. Feed 12V lights from a 48V off-grid or mobile battery bank.
Practical Comparison
5 Amp Versus the 10 and 20 Amp Models
All three AIMS 48V to 12V converters share the same input and output voltage ranges. The 10 amp model supplies 10A continuous (12A max) and the 20 amp model 20A continuous (24A max), in longer cases that AIMS lists with thermal and load controlled heat dissipation. Choose the 5 amp model when your 12V load stays within 5A continuous.
Non-Isolated Versus an Isolated Converter
AIMS lists this converter as non-isolated, with a non isolated ground. If your system requires isolation between input and output, choose an isolated converter instead.
Buyer Guidance
Size It to Your Load
AIMS's instructions say to confirm the converter has enough capacity for your load. This model is rated 5A continuous and 6A max. Your battery source must be 48Vdc and your load 12Vdc.
Wire It as AIMS Specifies
AIMS calls for input cable larger than 22AWG and output cable larger than 18AWG, with a cable length limit of under 1m or 3 feet and 2-3.7 fork terminals. Turn the load off and connect it to the converter. Then connect the negative wire to the battery source, followed by the positive. Don't reverse polarity.
This May Be A Good Fit If
- You have a 48V battery bank
- Your 12V load stays at 5A or less
- You want a compact converter
Common Questions
What Output Voltage Does It Provide?
The DC output is 12.5 to 13.5 Vdc.
What Happens if My Battery Voltage Gets Too Low or High?
The converter shuts down when input drops to 40 ± 2 V or rises to 59 ± 1 V.
Can I Mount It Where It Gets Wet?
No. AIMS says not to expose the converter to rain, snow, spray, bilge or dust. Mount it in a dry location with room for the wiring.
What Warranty Does It Have?
AIMS lists a 2-year warranty from the date of purchase.
