注意 :

1. 當(dāng)負(fù)載電流為 10A 時 , 必須加裝散熱器 ; 為 40A 及以上時 , 必須加風(fēng)扇強冷或水冷 .

2. 使用感性負(fù)載時 , 務(wù)必在輸出端并接一個壓敏電阻 , 取值為負(fù)載電壓的 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.
