Hello to all. I am searching for a multivoltage power supply which are to be mounted on the DIN rail of a cabinet. What I am actually interested in are 12Vdc and 24Vdc outputs with an input of
230Vac. The loads I am considering in my circuit draw about 1 Amp from the 12Vdc source and about 3Amps from the
24Vdc source. As I am designing a redundant power supply I would need to have 2 Power supplies in parallel so in case one fails the other takes over so I would also like to know whether the power supplies have an incorporated diode that idealizes this function. I am also considering using one of the 12Vdc power supplies with a dual output for this function. By connecting the both 12V outputs in a series connection I would have my 24Vdc and at the 12V nodes i could power my 12V load. Another option would be to get the 24Vdc power supply and using a resistive bridge or zener diode lower the voltage to 12Vdc or another integrated circuit ...however I would have to cope with heating losses and high wattage extra components. Could you please advice me on my best options. I am familiar with TDK Lambda power supplies for DIN Rails. As this is circuit has to always work I would need a reliable and top notch manufacturer. Thanks in advance. Gerard
