ACV 30.3520-06 Voltage transformer 1 pc(s) Output voltage (details)=12 V Operating voltage=24 V

This cool box accessory functions as a DC voltage conversion module that accepts a higher-voltage vehicle supply and delivers a lower-voltage output suited to 12V cooling equipment. The unit is installed inline with the cool box power lead so that the incoming supply is routed through the converter before reaching the appliance. Internally it regulates and steps down the voltage to deliver a consistent lower-voltage feed appropriate for portable fridges and similar devices. Typical use cases include retrofitting caravans and motorhomes or replacing a failed converter in automotive cool box systems, where reliable conversion from a vehicle electrical bus to the appliance supply is required.
