DIY KIT Adjustable Power Supply Module Step Down 24V AC to 0-30V DC 3A - BELUM DIRAKIT

DIY KIT Adjustable Power Supply Module Step Down 24V AC to 0-30V DC 3A - BELUM DIRAKIT

INPUT : 24V AC (dari trafo) bisa juga dari 12~30V AC
OUTPUT : Bisa diatur dari 0~30V DC (stabil meskipun input turun naik)
Arus Out : Bisa diatur/dibatasi 2mA ~ 3Ampere (Constant Current)

*Belum termasuk trafo (rekomendasi trafo output sekunder 24V 3A)
*Output maksimal (batas atas) tergantung tegangan trafo
*Sebaiknya TR final (D1047) diberi tambahan pendingin alumunium/+kipas
*Potensiometer dapat dipasang menggunakan kabel agar panjang
