64 PMC-A
Table 5-4 Monitor output of output voltage and
output current
・ Shorting V MON and I MON to A COM can cause
damage to the PMC-A.
・ Monitor output rating
Output impedance : 1 kΩ or less
Maximum output current : Approx. 10 mA
・ The monitor outputs are used to monitor the DC voltage
(mean value). They cannot be used to accurately monitor
the AC components (ripple, transient response, etc.) of
the actual output voltage or current.
5.2.2 External monitoring of the operating status
The J2 connector consists of status outputs that is used to exter-
nally monitor the operating status of the PMC-A. The follow-
ing five status outputs are available.
The outputs are open collector outputs of photocouplers; they
are insulated from the internal circuits of the PMC-A.
