BeautyPower's multi-output power supplies (such as 2 sets of outputs or more) have minimum load requirements. Therefore, it is especially recommended to read the product specification carefully before use. For multiple groups of output power supplies to operate normally, each group of outputs has a minimum current requirement, otherwise the output voltage will be unstable or exceed the defined voltage error range. The minimum load requirement can refer to the "current range" in the specification, as shown in the following table: CH1 requires a minimum current consumption of 2A, CH2 requires 0.5A, CH3 requires 0.1A, and CH4 requires a minimum current consumption of 0A.
