Samlex SDC-30 24 Volts to 12 Volts DC Converter, 30 Amps
Samlex SCD-30 24 Volts to 12 Volts DC Converter at 30 Amps
NOTE: This unit is rated for 30 Amps continuous output and 35 Amps peak output.
Samlex SDC-30 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, 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 output, use #6 AWG wire at a maximum length of 6 feet or #4 AWG wire at a maximum length of 10 feet. Use #8 AWG multi-strand wire on the input for up to six feet or #6 AWG for up to ten 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, 30A fast blow fuse for both the input and the output.
