Typically, the surface environment of a circuit board is determined to be either Pollution degree 3 or pollution degree 2.If the circuit board is mounted in an electrical box and sealed with a solid sealant, the sealing will look as follows: What should be…
The following circuit diagram The current fuse in position F1 is usually connected in series with the line.The photos of the real thing are shown in the following two pictures, the left one is not labeled, the right one shows the location of the current fuse and some other basic information. In the diagram above,…
Ada catatan pada tabel 17 dan tabel 18 sebagai “Untuk tegangan kerja dan gt; 10 V dan ≤ 630 V, jika tegangan tidak ditentukan dalam tabel, nilai jarak rambat dapat dicari dengan interpolasi.”. Jika tegangan operasi tidak sesuai dengan nilai yang tertera pada tabel, maka biasanya kita perlu menghitung untuk mendapatkan nilai batasnya, untuk memudahkan…
