Source, 36V ADAPTER FOR WATER PURIFIERS, MIST SPRAYERS

Regarding the principle of operation, the 36V Power Supply also has the same principle as a 12V power supply or a 5V power supply. Convert from current 220 -240V input via 2 primary rolls – Secondary to switch down current instead of transformer block lower voltage to 12V or 5V, the 36V power supply will convert voltage to 36V.
Depending on the purpose of use, different applications, users can use different power supplies.

Usually, when using, it is necessary to calculate the maximum capacity of use = 70% of the maximum capacity that the power supply can provide.
