Power Supply Operating States

Power Supply Operating States
The power supply has 5 operating states:
•
Power-On
•
Output Shutdown
•
Soft Start
•
Normal Operation
•
Calibration
Power-On
This is the period between the time that AC power is applied to the supply (AC
breaker turned on) and the time that the power supply is ready for operation.
During this period, the internal circuits are powering up and performing self-tests.
At the end of the Power-On period, the supply is normally in its default Power-On
mode with the output OFF, V
SET
=0 and I
SET
=0.
Output
Shutdown
In this state, the output is disabled and there is no output regardless of power
settings. The power supply can be placed in the Output Shutdown state by a
command (via the front panel or from the programming interface), via the
Interlock signal, or from a protection mechanism. This is also called the Standby
mode.
Soft Start
In this state, the output power is ramping up gradually towards its target load. This
reduces equipment stress. This state occurs whenever the supply output is set to
ON or a protection state is re-set, and is approximately 2 seconds in duration.
Normal
Operation
This is the normal operating state for the power supply. The power supply is ready
to accept commands.
Calibration
This is a service mode that is used to calibrate setpoints and readback levels for
accuracy. Calibration should only be performed by qualified service personnel.
