Transformers DC-DC voltage are used when the DC output voltage of the PV system does not meet the needs of consumers.

Different types of voltage transformers provide power 12 V steady since most low-voltage equipment (lamps, multimedia devices, radios or mobile phones) require a voltage 12 In. For example, When using a lamp of low energy 12 V in a system 24 V ou 48 In, we must add a voltage transformer suitable DC-DC between the output of consumer charge controller and lamp 12 V low power consumption.

Voltage transformers MDC and MDCI are designed for use in photovoltaic systems. Models with an output voltage of 13,6 V can also be used as a battery charger for 12 V in a system 24 In.

For safety reasons, the Steca MDCI series is electrically isolated to ensure consumer protection. The series Steca Steca MDCI and MDC are protected against voltage peaks at the input of, which prevents any voltage may cause damage to the input of consumers.
