Make secondary wire connections of transformer and measure the voltages as mentioned below
- Keep on/off switch in off.
- Keep Variac in series mode.
- Switch on the power supply. Mains voltage
: 240V, 50Hz.
- Check that mains voltage is not less than 175V
- If there is no loading then switch Variac to parallel mode.
- Check the AC/DC voltages as mentioned below.
