#MAGNETEK POWER CONVERTER MODEL 6345 MANUAL#

'When 120 VAC is NOT connected to the Electrical Center via commercial power or AC generator, put MANUAL SWITCH in 'BATT' position. 'Equipment limited to operation from pure 12 volt battery power including 12 volt TVs, radios, stereos, unfiltered fluorescent lights - must be connected directly into RV storage battery line, or equipped with filter - as Converters do not produce the 'pure' 12 volt DC needed by these items.' 'Provides 12 volt DC power - up to load limit - to operate 12 volt lights and motors in RV when connected to 120 volt power source.'

There is a connection for a battery but it goes into a selector switch so the loads that are powered from the 'converter' can be switched over to the battery when there is no mains power. I can draw up a circuit diagram and choose the components if you tell me how much current you need to draw from the regulated and smoothed 12V rail.Īccording to the manual (also linked in the first post) it is not a float charger. This requires a circuit consisting of about ten components, which you can build up on a piece of stripboard. Your best option for powering devices that need clean DC is a low dropout (LDO) regulator, powered from a large smoothing capacitor that's fed from your 'converter' via a diode. If you are only loading it lightly, and/or if one or more of your loads includes a large capacitor that 'smooths out' the voltage in between the camel humps, the voltage you measure on your multimeter will be higher than the specified 12V. The characteristics of the output voltage will depend on what it's connected to. The output voltage consists of a line of camels' humps, not a flat DC voltage, as shown on the right in this picture.Īs the manual says, 'equipment limited to operation from pure 12 volt battery power including 12 volt TVs, radios, stereos, unfiltered fluorescent lights - must be connected directly into RV storage battery line, or equipped with filter - as Converters do not produce the 'pure' 12 volt DC needed by these items.'

It's 'DC, Captain, but not as we know it'. That 'converter' is a full-wave rectified power supply without smoothing. Hi there and welcome to Electronics Point
