NOTE:
1. Due to high speed and large surge voltage switching, the area P-C1-N should be a small as possible. (C1: good temperature,
frequency characteristic electrolytic type). Also add a bypass condenser (C2) with good frequency response such as polypropylene
as close as possible to the P and N terminals.
2. To prevent erroneous protection, the wiring of A, B should be as short as possible.
3. It is recommended to insert a high-speed clamp diode between V
NO
-GND terminals to prevent surge destruction.
4. C3 and C4 capacitors should be mounted as close to the terminals of the DIPPFC as possible. C3, good temperature, frequency
characteristic electrolytic type and C4, good temperature, frequency and DC bias characteristic ceramic type are recommended.
5. It is recommended to insert a Zener diode (24V/1W) between each pair of control supply terminals to prevent surge destruction.
6. Please connect adjacent terminals with the same name together on the PCB. (N, N2, V

7. Do not connect RG and SG terminals to any wire on the PCB.
