Term Definition
Constant Current  A regulated power supply that delivers a constant current to a load, even when the load resistance changes. Note that the power supply must follow Ohm's Law. 
Constant Voltage  A regulated power supply that delivers a constant voltage to a load even when the load resistance changes to a value that will not exceed the power supplies current limit. 
GPIB  General Purpose Interface Bus also known by its Institute of Electrical and Electronics Engineers standard IEE-488. 
Isolation  Floating output, no reference to any voltage. 
Line Regulation  How much the load voltage or current changes when the power supply is operated at varying line voltages throughout a given range. Typically stated as a percentage of the total voltage or current available from the supply. A rating of "0%" would mean perfect regulation. 
Linear Power Supply  Uses a transformer to convert the voltage from the mains to a different voltage. 
Load Regulation  How much the load voltage or current changes between operating the power supply at no-load and full-load conditions. Typically stated as a percentage of the total voltage or current available from the supply. A rating of "0%" would mean perfect regulation. 
Noise  The portion of unfiltered and unshielded EMI noise present at the output of a filtered power supply, operated at full load. Typically stated in peak-to-peak AC voltages (with zero volts peak-to-peak representing a perfectly filtered & shielded power supply). 
Overload Protection  The means by which a power supply is protected from permanent damage due to short circuits, excessive loads, or reverse polarities connected across the load terminals. Protection may be as simple as a fuse (which can be economically replaced), or may be electronic protection conditions as well as power supply component temperatures. 
OVP  Abbreviation for Over Voltage Protection. It is the maximum voltage limit allowed before going in to OVP mode to protect both the instrument and the device under test. 
Power Consumption  The input power that is required by the power supply at a full load output condition. 
Programmable  Able to be programmed either by the front panel or by a connected PC. 
Recovery Time  The time that it takes a power supply to regulate its output after an abrupt change, such as from full load to no load. 
Regulation  The ability to maintain a constant voltage or current at the load despite changes in line voltage or load resistance. 
Remote Sense  Ensures that the voltage at the load is the same as the power sources set voltage. The remote sense feature compensates for any voltage drop between the source and the DC electronic load. 
Resolution  The smallest increment of change that can be indicated on a display. 
Ripple Current  The portion of unfiltered AC current at the output of a filtered power supply. 
Ripple Voltage  The portion of unfiltered AC voltage and noise present at the output of a filtered power supply, operated at full load. Typically stated in rms AC voltages (with zero ripple voltage representing a perfectly filtered power supply). 
RS-232  Recommended Standard 232 serial interface. 
SCPI  Abbreviation for Standard Commands for Programmable Instruments. 
Switching Power Supply  Uses transistors instead of a large transformer to convert the voltage from the mains to a different voltage. 
Temperature Coefficient  The change in power supply output voltage that is caused by temperature change. It is usually expressed in millivolts per degree (mv/degrees C). 
Tracking  Two power supplies (within on case) that are electrically coupled so that both can be varied by using only one knob. 
Transient Response Time  The time it takes for the output voltage to recover to within a certain voltage (usually 15mV) following a change in output from full load to half load (or vice versa).. 
USB  Universal Serial Bus. 
VA  Abbreviation for Volt-Ampere. Unit of input power delivered to a load. For electronic equipment, the "V/A" load imposed on the isolation transformer or AC power supply is simply the load voltage multiplied by the load current, or the wattage rating of the load.
