TEXIO PSF-1200L - Various Status Signals (CV, CC & ALARM)

56
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
