series 2200 Single-Channel Programmable DC Power Supplies The Series 2200 Single-Channel Programmable DC Power Supplies provide a wide range of voltage outputs to address the testing and characteriza- tion of components, circuits, modules, and complete devices, whether you are in a research laboratory, in design and development, or in production test . The Series 2200 consists of five models with output voltages from 20V to 72V that can deliver 86W, 96W, 100W, and 150W of power . In addi- tion, these power supplies can act as constant current sources as well as constant voltage sources . The Series 2200 power supplies offer an excellent combination of performance, versatility, and ease of use that allow you to obtain quality test data as quickly as possible . They perform as effectively in automated test systems as they do in manual instrument configurations . o utstanding accuracy Delivered to the l oad With basic voltage setting accuracy of 0 . 03% and basic voltage readback accuracy of 0 . 02%, you can be sure that the voltage you program for the load is applied at the output terminals . Whats more, the rear panel con- nections include remote sense terminals that compensate for voltage drops in the power supply leads . This helps to ensure that the correct voltage is delivered to the load termi- f ive models ranging in power nals of the device-under-test (DUT) . Great accuracy is not limited to voltagethe basic current setting from 86W to 150W with voltage and readback accuracy is 0 . 05%, providing you with high quality load current measurements . Also, outputs from 20V to 72V with less than 5mVp-p noise, you can be confident that the power applied to the DUTs load termi- address a wide range of power nals is both accurate and of high quality . requirements Superior resolution is also provided by Keithleys Series 2200 single-channel power supplies . With 0.03% basic voltage output 1mV and 0 . 1mA resolution, the effects of very small changes in voltage and current can be detected accuracy and 0.05% basic and studied . For portable devices in which minimum power consumption is critical, the 0 . 1mA cur- current accuracy provide rent resolution allows you to measure the idle and sleep mode currents so you can verify that your quality test data products meet aggressive low power consumption goals . High output and measurement Get Test r esults Quickly resolution, 1mV and 0.1ma , Keithleys Series 2200 single-channel power supplies have a number of features that enable you to for testing low power circuits obtain the results you need quickly and easily, including tools to help you create sophisticated tests and devices for a wide range of requirements . r emote sensing to ensure the The dual-line display shows both the programmed settings and the actual voltage and current out- programmed voltage is applied puts, allowing you to immediately see, understand, and address any differences between the expect- to the load ed and actual output values . Multiple methods can be used to adjust the voltage and current settings . Dual-line display shows both You can use the direct-entry numeric keypad to set precise voltage and current values . There is also a the programmed values and rotary knob with adjustable step size that lets you easily study the response of your DUT to small or actual outputs for a continuous large changes in voltage or current . indication of the status of the Need to repeat a set of tests often Instead of programming a number of parameters for each test power delivered to the load every time you run the test, just use a few keystrokes to save a test setup once and then recall it r epeatable test sequences whenever you need it . Take advantage of 40 memory locations to save up to 40 set ups or use the of up to 80 output steps are Series 2200 List mode to define custom test sequences of up to 80 steps . This makes it easy to per- easy to create with the built-in form tests such as analyzing how your circuit- or device-under-test performs at each voltage level l ist mode within a range of voltages . A saved test can be run manually using front panel key strokes, automati- cally using external trigger signals, or remotely using programmable interface commands . Up to GPIb and usb interfaces seven 80-step lists can be stored in a Series 2200 single-channel power supply . Each step can have a are standard for convenient programmable duration . automated control Protects Your DuT at all Times A number of features are built into the Series 2200 power supplies to ensure that your DUT is pro- tected from damage . A maximum voltage can be set so that regardless of the voltage value requested, the output will not exceed the programmed limit value . For further voltage magnitude protection, an Over Voltage protection level can be programmed that will cause the output to drop below 1V if the Over Voltage limit is reached . These protections are in addition to the Current Limit setting, which restricts the amount of current that can flow into the DUT . If the Current Limit is reached, the Series 1.888.KEITHLEY (U.S. only) www.keithley.com A Greater Measure of Confidence Single-channel programmable DC power supplies DC POWER SUPPLIES Single-channel programmable DC power supplies 3-Year Warranty series 2200 Single-Channel Programmable DC Power Supplies 2200 power supplies convert from constant voltage to constant current operation in which the cur- ordering Information rent is controlled at the Current Limit setting and the voltage varies based on the load resistance . 2200-20-5 Programmable DC In addition to the limit settings, you can set a timer to turn off the output after a specified time inter- Power supply, 20V, 5a val, allowing you to setup a test on your bench and let it to run unattended knowing that power will automatically be removed from the DUT after the programmed time has elapsed . 2200-30-5 Programmable DC Power supply, 30V, 5a Ensures that Test Parameters are Not accidentally Changed 2200-32-3 Programmable DC Prevent accidental changes to settings to avoid collecting incorrect test data and wasting time repeat- Power supply, 32V, 3a ing tests by taking advantage of the Series 2200s front panel lock-out functions .

Model Number-EW (Example: 2200-20-5-EW) 1 additional year of factory warranty The remote sensing technique solves the problem of voltage drop in the leads by extending C/Model Number-3Y-STD the power supply feedback loop to the input of the load. Two sense lines from the power 3 calibrations within 3 years of purchase C/Model Number-3Y-DATA supply are connected to the power inputs. These sense leads are voltage measuring lines 3 (ANSI-Z540-1 compliant) calibrations within that connect to a high impedance voltage measuring circuit in the power supply. Since the 3 years of purchase voltage measuring circuit is a high input impedance circuit, the voltage drop in the sense C/Model Number-5Y-STD leads is negligible. The sense lead voltage measurement circuit becomes the feedback 5 calibrations within 5 years of purchase C/Model Number-5Y-DATA control loop for the power supply. The voltage at the load is fed back to the power supply 5 (ANSI-Z540-1 compliant) calibrations within by the sense leads. The power supply raises its output to overcome the voltage drop in the 5 years of purchase source leads and V = V . Load Programmed Thus, only with remote sensing can the accuracy of the power supply be applied to the load. 1.888.KEITHLEY (U.S. only) www.keithley.com A Greater Measure of Confidence Single-channel programmable DC power supplies DC POWER SUPPLIES Single-channel programmable DC power supplies
