What does a on-board DCDC look like?(3)

The core of the Marine boost/buck voltage power supply is the IC, just like the brain of the Marine boost/buck voltage power supply, the quality of the IC directly affects various parameters of the Marine boost/buck voltage power supply.

Three: Transformer components

Determine the power and temperature resistance of the Marine boost/buck voltage power supply, it is the transformer. The transformer is responsible for the completion of AC and DC, and the energy overload will saturate the machine.

Four: Electrolytic capacitors and ceramic capacitors

(1) After opening the package, it is necessary to carefully check whether the identification of each terminal is in line with the instructions that are brought along with it, and whether it is in line with the requirements of the order contract. If it does not match, you should immediately contact the production or sales unit to discuss how to deal with it.
(2) As the first step of installation, the metal casing of the module power supply must be grounded reliably to ensure safety, but the casing should not be connected to the zero line by mistake.

Electrolytic capacitors, as well as monolithic electrolytic capacitors, which use sulfuric acid as the insulating medium, which allows for greater capacity savings, are made into smaller volumes, and are marked with a + symbol, some with an a symbol. Typically used for low frequency crosslinking and bypass filtering. The disadvantage is that the loss of mesons is greater. Monolithic electrolytic capacitors are due to their special properties. The performance of the material is better than that of ordinary electrolytic capacitors, and the frequency characteristics are better, but the capacity cannot be too large, and can be used in precision circuits and timing circuits.
