注意 :

1. 当负载电流为 10A 时 , 必须加装散热器 ; 为 40A 及以上时 , 必须加风扇强冷或水冷 .

2. 使用感性负载时 , 务必在输出端并接一个压敏电阻 , 取值为负载电压的 1.6-1.9 倍 .

Notice:

1. If the load current is 10A, a heat sink must be equipped; if the load current is 40A or more, an air-cooled radiator or a water-cooled radiator must be installed.

2. When the load is an inductive load, be sure to connect a varistor in parallel with the output terminal, whose voltage value is 1.6-1.9 times the load voltage.
