External Monitoring
External monitoring of the output voltage and output current PWX
series
The J1 connector has monitor outputs for the output voltage and the output current.
Monitor output rating
Output impedance: 1 k
Ω
or less. Maximum output current: Approximately 10 mA.
The monitor output signals are used to monitor the DC voltage (mean value). They cannot be
used to accurately monitor the AC components (such as ripple and transient response wave-
form) of the actual output voltage or current.
External monitoring of the operation status
The J1 connector has status outputs that can be used to externally monitor the operation sta-
tus of the PWX series. The following five items make up the status outputs.
The outputs are open collector outputs of photocouplers; they are isolated from the internal
circuits of the PWX series.
The status common is floating (that is, it has an isolation voltage of less than or equal to 60
V).
If connected for master-slave parallel operation, STATUS COM (pin 1 of the J1 connector) of
the master unit will be connected to A COM (pin 19 of the J1 connector) of the slave unit (it
will no longer be floating). If the positive output terminal is connected to the chassis terminal
in this condition, the status common will be at an electric potential that is lower than that of
the chassis terminal by the output voltage. Because the positive output terminal is at ground
potential, secure an insulation capacity greater than or equal to this product’s isolation volt-
age relative to the chassis.
The maximum ratings of the signal terminals are as follows:
Maximum voltage: 30 V. Maximum current (sink): 8 mA.
Pin no. Signal name Description
10, 19, 23 A COM Remote control input common
Output monitor common
25 V MON Monitor output of output voltage
0 to approx. 5 V (CF08: Lo) or 0 to approx. 10 V (CF08: Hi) for 0 to the
rated output voltage
24 I MON Monitor output of output current
0 to approx. 5 V (CF08: Lo) or 0 to approx. 10 V (CF08: Hi) for 0 to the
rated output current
CAUTION
Shorting V MON and I MON to A COM may damage the PWX series.
