Single Phase Fully Controlled Bridge Converter
Product Code : JA-PET-1427
The single phase fully controlled bridge converter trainer lets students build and study a four-SCR bridge supplied from a 230 V AC isolated transformer rated at 50 W. Two UJTs with 1:1:1 pulse transformers generate the firing pulses, two potentiometers set the firing angle, and a 40 W, 230 V AC bulb is fitted on the board (SKU JA-PET-1427).
