Standard Operation

Standard Operation

The power supply can be controlled by two methods, either from the front panel or from any of the remote interfaces. Front panel control is referred to as local operation (default setting) while control via any of the remote interfaces is called remote operation. To set up the power supply for remote operation, see Chapter 5, “Remote Operation”. Once the remote connection has been established, the power supply can switch seamlessly between local operation and any digital interface (RS-232, RS-485, GPIB, USB and Ethernet).

	Local lockout is a feature that allows the front panel to be locked so that
	accidental button presses are ignored. This feature is often used to lock

	out the front panel while a user is controlling the power supply from a
	remote location.	3
	The output of the power supply has two modes of operation: Constant	3
	Voltage (CV) mode (see page 3–12) and Constant Current (CC) mode

	(see page 3–12). Both of the operating modes are available regardless of
	which control method (local or remote) is used.
Operating Modes
	The output mode in which the power supply operates at any given time
	depends on the following factors:
	• Output voltage set point VSET
	• Output current set point ISET
	• Impedance of the attached load RL
	The two output modes of operation are Constant Voltage (CV) mode (see
	page 3–12) and Constant Current (CC) mode (see page 3–12).
Output enabled	When the output is turned on, both the voltage and current rise as quickly
	as possible to try and reach the set points (VSET and ISET) that were
	configured prior to enabling the output. Initially the unit will operate in
	CV mode, which is the default mode. As the voltage and current rise to
	meet the requirements of the load, the set point that is reached first (based
	on the RL, either VSET or ISET) will determine which mode the power
	supply will remain in. The operating mode is indicated by either the CC
	mode LED or the CV mode LED, one of which will illuminate on the
	front panel.
Output disabled	The mode of operation is not determined until the output is enabled. The
	CV and CC mode LEDs will not indicate the mode while the output is
	disabled.
