6.1 Output Current Monitor
¿
PBA300F, PBA600F, PBA1000F, PBA1500F
and PBA1500T
¡
You can monitor an output current by measuring a voltage be-
tween the terminal CB and the terminal -S on either CN1 or CN2.
¡
Fig.6.1 shows the relationship between the voltage of the terminal
CB and the output current.
Fig.6.1 shows a typical characteristic of PBA1500F-5. Please
contact us for the characteristics of the other models.
The output current shown in Fig.6.1 should be used only as a
guide.

¡
Fans should be exchanged on a regular basis because their life
expectancy (R (t) = 90%) vary depending on use conditions as
shown in Fig.5.5. Please see ”Optional Parts” for details about
fan units.
