Conversion Instructions
1) Remove C2, C13-17, D1-4, L1, T1, U1, and RT1. Retain mounting screw and nut
from U1 heat sink for reuse.
2) Replace C2 with 150 µF, 200 V capacitor from conversion kit. Observe proper
polarity.
3) Replace C13, 14, 16, and 17 with 1200 µF, 35 V capacitors from conversion kit.
Observe proper polarity.
4) Replace D1-4 with RL205 diodes from conversion kit. Check for proper diode
polarity according to PCB silkscreen.
5) Replace L1 with 18 mH common mode inductor from conversion kit.
6) Replace U1 with TOP247Y from conversion kit. Use thermal compound between
device mounting tab and heat sink to assure proper thermal interface.
7) Replace T1 with transformer from conversion kit.
8) Replace RT1 with thermistor from conversion kit.
9) Populate C21 and C22 positions with 0.1 µF capacitors from conversion kit.
10) Populate R12 position with 18 kΩ resistor from conversion kit.
11) Populate JP5 position using zero ohm resistor from conversion kit.
