Pada umumnya catu daya selalu dilengkapi dengan regulator tegangan.Tujuan pemasangan regulator tegangan pada catu daya adalah untuk menstabilkan tegangan keluaran apabila terjadi perubahan tegangan masukan pada catu daya. Fungsi lain dari regulator tegangan adalah untuk perlindungan dari terjadinya hubung singkat pada beban. Salah satu metode agar dapat menghasilkan tegangan output DC stabil adalah dengan menggunakan IC 78XX untuk tegangan positif ...

Sebelum kita membahas cara kerja dari AC Generator/Alternator agar membantu kita pelajari secara singkat DC generator untuk melihat charging sistem dalam persepektif yang tepat. Generator DC seperti tampak pada gambar 1.5 terdiri dari rangkaian armature, dimana sebuah inti besi lunak bercelah dengan banyak jalur kabel. Armature ini diletakkan didalam housing dimana mengandung medan electromagnet. Gambar 1.5 Generator DC Pada titik ...

Terminal voltage source found in numbers 2-7, NO contacts on the terminals 1-3 and 6-8 and NC contacts are on terminal 1-4 and 5-8. Picture 5-13. Relations terminal relay delay time (TDR). Picture 5-14. The front of the relay delay time (TDR). Picture 5-15. Mode ...
Read More »A transistor is a component which is the main building of the development of electronics. Semiconductor devices are typically classified into two major divisions, namely: Juction Bipolar Transistors (BJT) or commonly called the A and Field Effect Transistor Transistor (FET). This chapter, and the next several chapters, will discuss the characteristics, configuration and use of transistors in electronic circuits. In ...
