Samlex SDC-60 24 Volts to 12 Volts DC Converter, 60 Amps


Samlex SCD-60 24 Volts to 12 Volts DC Converter at 60 Amps

Note: This unit is rated for 70 amps peak output and 60 amps continuous output.

Samlex SDC-60 non-isolated DC to DC converter, 24 volts DC to 12 volts DC. This is used when you have a 24 volt DC battery system but need to run equipment, such as DC lights, marine radio, AM/FM radio, CB or HAM radio, or other devices that require 12 volts DC. This avoids "tapping" a 24 volt battery system which can lead to uneven battery charging and early battery failure due to unbalanced charging. To minimize the voltage drop to 2% on the input and output, use #4 AWG wire at a maximum length of 6 feet or #2 AWG wire at a maximum length of 10 feet. If you will be powering voltage sensitive devices with minimal tolerance, you will want to use the largest size wire that's suitable for the situation. As the wire gets larger, the voltage drop decreases. Be sure to read the installation instructions and follow the fuse guidelines. You will need fuse protection on both the input and the output positive wires. Bussmann automotive type fuses (ATC or ATM) will work fine. Use a 32V, 60A fast blow fuse for both the input and the output. You may also use two 30A fuses in parallel for the input and the output.
