Figure 30: UBA Display window (click on the UBA icon in the UBA Network window to
get this display, then click on the General button). In this example, the UBA Console S/W
will limit its power supply current draw to no more than 1.0A.
You can change this value by entering in a new one, but note that this number is not saved into the calibration file.
Remember that a value of 0 (zero) means that the UBA will not limit its power supply current draw (but will never
exceed 4.25 A).
Sharing Power Supply Current Between Both Channels
You can specify that both channels equally share the power supply current by checking the Evenly divide between
channels radio button on the Charger tab in the Options dialog box (File menu). This evenly divides the power
supply current among both channels so that each channel can have up to half the maximum current.
Figure 31: Option dialog box showing the Charger current settings.
Examples:
1.
You have a power supply with a 4.25A or greater output current rating. Since the power supply can supply
both channels with their maximum current rating (2A) with at least 250mA left over for the UBA's electronics,
then no output current limiting is necessary. Either a setting of 4.25 or greater or 0 in the power supply rating
box is acceptable. The Power Supply Current radio button selection has no effect.
