So that you can see only here in the specifications
Basic items
There are many items in the specifications, and many people may not know where to look.
There are other items that you should look at, but at least the four items below are the ones you should look at.
・ Rated output voltage
・ Maximum output current
・ Operating (use) temperature
The “operating (use) temperature” in this is important. Indicates the load factor (%) that can be used depending on the ambient temperature of the power supply.
The higher the load factor, the better, but I think it’s a good idea to select a load factor of 80% when the ambient temperature is 50 ° C.
The actual specifications indicate the operating temperature as shown below.
“-10 to +60 (-10 to + 40 ° C: 100%, + 50 ° C: 80%, + 60 ° C: 60%”
In this example, it means that the load factor can be used at 100% from -10 ° C to + 40 ° C, 80% at 50 ° C, and 60% at 60 ° C.
Also, the style of the specifications is different for each power supply manufacturer, so this can only be used.
If you use the search function of this site, you can easily find the load factor at an ambient temperature of 50 ° C without having to check the specifications of each power supply manufacturer.

Series connection and parallel connection
One of the most frequently asked is the series connection and parallel connection of power supplies.
Raising the voltage value is in series operation, and raising the current value is in parallel operation.
Power supplies can be connected in series, but some can be connected in parallel and some cannot, so check the specifications. Multi-output power supplies cannot be connected in series or in parallel.
In addition, please see another article that explains how to connect in series and in parallel.
That is all for the contents. Thank you for reading.
