5-7-7. Various status signals (CV, CC & ALARM)
It is possible to check the status using the open collector output.
■
Constant-voltage (CV) status signal
This status signal goes Low when the PSF Series power supply unit
enters the constant-voltage (CV) status.
■
Constant-current (CC) status signal
This status signal goes Low when the PSF Series power supply unit
enters the constant-current (CC) status.
■
Alarm status signal
This status signal goes Low when the PSF Series power supply unit
enters the alarm status.
