Power Supply Operating States

The power supply has 5 operating states:

•Power-On

•Output Shutdown

•Soft Start

•Normal Operation

•Calibration

Power-OnThis 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, VSET=0 and ISET=0.

Output In this state, the output is disabled and there is no output regardless of power settings. Shutdown The power supply can be placed in the Output Shutdown state by a command (or the

the front panel - XFR, XHR only), 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 enabled by the software (a command or a protection is cleared), and is approximately 2 seconds in duration. See “Slew Rate” on page 67 to change the properties of the ramp.

Normal This is the normal operating state for the power supply. The power supply is ready Operation 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.
