Power Protection Circuitry
To reduce the risk of damage due to power-supply problems, the utilityModule includes several
protective components.
Module Power-Supply Protection
The utilityModule includes a component to help prevent damage due to problems with the +5Vdc
power supply from the PC/104 bus. Protection is provided for:
Over-current
Reversed polarity
Excessive voltage
This protection is only for the utilityModule, and will not protect other devices in a PC/104 stack.
The protective fuse is replaceable and is available from electronics suppliers. Its description and
part number is:
Littelfuse Nano
2
SMF 1.0 amp, R451-001
Caution:
Replace fuses only with parts of identical current and voltage rating.
