2.2 Power capability
The PRO module can deliver the following power supply lines to the user defined electronics:
■
5V3 ±5%, 500mA max.
■
+15V ±5%, 100mA max.
■
-15V ±5%, 100mA max.
■
V
aux
: 15V to 30V ±5% (One programmable value per DAU power supply PSI or PSS, based on PRO/EXT modules
min/max range requirement, and ANA modules excitation constraints), 500mA max.
The power supply lines are accessible in the PRO module via PCB lands to be fitted with soldered wires and are
protected against overcharge (current limitation). The EXT module does not deliver power.
Note:
◆
V
aux
always starts at 30V at start-up. The programmed Vaux(e.g. 15V) is available only after a few
seconds, after configuration by the CPU.
◆
The power consumption of a complete DAU shall remain compliant with the maximum power deliv-
ered by the power supply modules (PSI and PSS).
◆
Contact ZODIAC DATA SYSTEMS to verify the power capacity of your DAU configuration.
◆
The user electronics shall not dissipate more than 5W in a PRO or EXT module.
◆
When using power from the DAU, the user shall implement proper filtering to avoid DAU perfor-
mance degradation.
◆
The PCB lands of the power supply lines allow a maximum of 3 soldering/unsoldering operations.
