Dalam panduan ini, saya akan menjelaskan cara kerja dimmer trailing-edge BQ-TTDIM dan mengapa ia bekerja sangat baik dengan driver LED.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Apa Itu Dimmer Trailing Edge?<\/h2>\n\n\n\n<p>Banyak installer menganggap semua phase-cut dimmer bekerja dengan cara yang sama.

Dimmer memodifikasi gelombang sinus AC yang memberi daya pada beban pencahayaan. Dengan menghilangkan sebagian gelombang, dimmer secara efektif menurunkan tegangan RMS yang dikirim ke lampu.<\/p>\n\n\n\n<p>Saya sering menjelaskannya dengan cara sederhana. Bayangkan gelombang AC sebagai gelombang kontinu. Dimmer memungkinkan gelombang dimulai secara normal. Kemudian dimmer mematikan arus sebelum gelombang selesai.
