1. The risk of electric shock is different
1. Non-isolated bai power supply: The load end of the non-isolated power supply is directly connected to the input end. The non-isolated power supply will introduce the high voltage of the AC power supply to the load end, thereby causing the risk of electric shock.
2. Isolated power supply: The load end and input end of the isolated power supply are indirectly connected, so there is no risk of electric shock when touching the load.
2. Different drive efficiency
1. Non-isolated power supply: The drive efficiency of non-isolated power supply is higher, and the voltage range is between 110-300V.
2. Isolated power supply: The drive efficiency of isolated power supply is low, and the voltage range is between 60V-300V.
Three, the cost is different
1. Non-isolated power supply: The circuit structure of the non-isolated power supply is a DC/DC step-up or step-down circuit scheme, so the circuit is relatively simple and the cost is relatively low.
2. Isolated power supply: The circuit structure adopted by the isolated power supply is an AC/DC flyback circuit scheme, so the relative circuit is more complicated and costly.
