2.2 Power Requirements
The module
’s power supply must comply with the requirements given in Table 2.1.
The module is powered via the PC/104 and PC/104-plus connector (if installed). If an external
power supply is required, an additional XP22 power connector (4-pin AMP 4-171826-4 connector)
can be used.
For versions 3.x and below, the starting current of the module is 2.1 A for the CPC307-02 version.
The power supply source must be capable of providing the starting current. A power supply source
with a current limiting mode of at least 1.2 A can be used. When selecting a power supply, the
starting current and the current consumption of the expansion modules must be taken into account.
The module version 4.0 and higher have a
“soft” start mechanism. The module’s power-up delay
after applying power is about 200 ms (max). To ensure a certain level on the I/O port lines within
200 ms after power-up, additional measures must be taken.
Attention!
It is recommended to take additional measures to ensure protection of external
devices against "+5 V" conductive interference in case of using one voltage output
of the power supply.
Consumption current typical value is 0.6 A.
