DC/DC converters are used, depending on the model, to step up or to step down a DC voltage or to provide the same voltage but stabilised. They can be used to charge one battery bank from another.

The Cristec 12/24 - 30A is a DCDC Converter specifically designed to act like a battery charger to charge a 24V bowthruster battery from a 12V service battery bank. It will convert a 'nominal' 12V supply into 24V with a maximum output current of 30A @ 24V in such a way as to mimic the behavior of a sophisticated 30A 5-stage mains battery charger.

Cristec DCDC Converters are all galvanically isolated.

Overview
 

Overview

DC/DC Converters can be used (depending on model) for three distinct purposes:

1.  To provide a supply of power for a device which uses a different voltage from the service voltage available on the vessel.

2.  Convert a service voltage into a different voltage to facilitate battery-to-battery charging. This option can be accomplished in a simple way using any DC/DC converter with an output voltage that is slightly higher than the resting voltage of the battery. So, to charge a 12V battery from a 24V battery bank, the DC/DC converter should have an output higher than 12.8V. This output voltage is adjusteable on Cristec DCDC converters. There is a specific model for charging 24V bowthruster batteries from a 12V supply using a modern 5-stage battery charging regime - see YPOWER DCDC Charger - 12 / 24 - 30A

3.  To stabilise power. When devices such as electric winches, bowthrusters or even powerful inverters are connected to the service batteries, they may cause a dip in voltage when used. This might affect navigation instruments, causing them to switch off and then back on again. This would be disruptive and may cause stored information to be lost. In this case a DC/DC converter which has the same nominal input voltage as its output voltage will act as a stabilised power supply. The input voltage may drop but the output voltage will remain at the exact voltage you have set using the internal potentiomenter. The current drawn from the input will rise to compensate for the drop in that voltage, ensuring the output power remains stable.
