DC power supply

Fuse: 5 to10A fuse at the shared terminal of output contacts to protect the output circuit

Transient voltage suppressor (SB360 3A 60V): Extends the life span of contact.
1. Diode suppression of DC load: Used when in smaller power [Figure 10a]
2. Diode + Zener suppression of DC load: Used when in larger power and frequent On/Off
[Figure 10b]
