DC-DC CONVERTERS AND BATTERY CHARGERS
MC / MG — DC-DC converter, 12/24/48 V, 3–30 A
Country: Netherlands · Model: MC / MG
A series of DC-DC converters rated 3–30 A for running 12 V loads from a 24 or 48 V onboard network. The second job of the series is voltage stabilization for sensitive consumers such as radios and navigation electronics.

Description
The MC series is step-down, while MG models with the -i suffix have galvanic isolation and a regulated output. Input is 12, 24 or 48 V DC, and output is 12.5–13.8 V or 24 V depending on the model. Voltage accuracy is 3% and ripple 1%, which is clean enough for radios and navigation instruments. The smallest model, the MC 24-12 at 5 A, delivers 70 W. The isolated versions go where the onboard negative must not be joined to the consumer negative, for example in a hull-insulated system on a metal vessel. The converter replaces a tap from the midpoint of a battery bank, which discharges the two halves unevenly and wears them out early.
How to choose
First decide whether isolation is needed, without it the step-down MC is enough, with it take an MG …-i. Size the current by the total of the 12 V loads plus margin, as the series covers 3–30 A. If there is a battery on the 12 V side that has to be charged, you need the MCC at 5–20 A with a 3-stage algorithm and 12–15 V adjustment. A small network up to 20 A can also run from the auxiliary 12 V output of the DC PowerCube.

FAQ
What current do the MC / MG DC-DC converters deliver?
From 3 to 30 A depending on the model.
What is the difference between the MC and MG …-i converters?
The MC units are step-down, while the MG …-i add galvanic isolation and regulation with 3% accuracy.
What is the power of the MC 24-12 5 A?
The MC 24-12 at 5 A delivers 70 W.
What is the output ripple of the MC / MG?
Ripple is 1% and voltage accuracy 3%. Output is 12.5–13.8 V or 24 V.
Why not take 12 V from the midpoint of a 24 V bank?
The lower half of the bank discharges more than the upper half, and the batteries quickly drift apart. An MC DC-DC converter draws evenly from the whole bank.
