CAUTION sign until the in- pose. ITECH shall not be held liable Manual Part Number dicated conditions are for errors or for incidental or indirect fully understood and met.
Warranty ITECH warrants that the product will be free from defects in material and work- manship under normal use for a period of one (1) year from the date of delivery (except those described in the Limitation of Warranty below).
Failure to comply with these precautions or specific warn- ings elsewhere in this manual will constitute a default under safety standards of design, manufacture and intended use of the instrument. ITECH assumes no li- ability for the customer’s failure to comply with these precautions.
♦ System Menu at a Glance 1.1 Brief Introduction ITECH newly-launched IT7200 High Performance Programmable AC Power Supply combines intelligence and flexibility, breaks through the huge defects of the traditional AC power source, reduces the size to only 1⁄2 2U, maximizes space utilization.

AC Power Input Level Working voltage for IT7200 series power is 220V, AC power input level: 220- 230Vac, 47~63Hz. Power Cord Type and Connecting Method IT7200 series contains many models.
VCP: USB_VCP virtual serial port. When the host software uses the USBVCP for communication(The WIN7/XP system needs to be installed with IT7221-VCP.inf. Download from the ITECH website or contact ITECH agent), this USB is the USB_VCP interface. 4. Press [Esc] to exit the system menu setting.

LAN Configuration: Reconfigure the LAN parameters. • Security: Change the password and control access to the Http interface. • Manual: Go to the ITECH official website and view or download the relevant documents. • Logout: Logout the Http interface. 2.6.2.2 Using Telnet The Telnet utility (as well as sockets), is another way to communicate with the instrument without using I/O libraries or drivers.
Page 38
The instruments allow any combination of up to six simultaneous socket and telnet connections to be made. ITECH instruments have SCPI socket services, which can be used to send and receive ASCII/SCPI commands, queries, and query responses. All commands must be terminated with a new line for the message to be parsed. All query re- sponses will also be terminated with a new line.

Wait until the power is turned off and then start again. If the problem still cannot be solved after restart- ing, please contact the ITECH engineer. Please refer to Error information list detailed information about common error messages.
♦ Protection Function ♦ System-Related Operations 4.1 Select the Output Mode The IT7200 series power supply has 3 output modes: AC, DC and AC+DC. The User should set specific output mode based on required applications. AC Mode This mode is the default mode when the instrument is powered on (It is neces- sary to press [Shift]+[3] (AC) key to switch the DC mode back to the AC mode), indicating that the instrument is used as AC power supply.
Press [Esc] key to exit the input mode. 4.2.3 Set the AC Phase Angle IT7200 series supports the initial phase and stop phase of the output waveform settable to meet different test requirements. The initial phase and stop phase are set in the range of 0.0°~359.9°. By adjusting the phase angle, the user can test the rush current of the product at different positions which is widely applied to various switch current impulse tests and various rectifiers test.
Press [Enter] key to confirm. 5. Press [Esc] to exit the configuration menu setting. • The user-defined waveforms need to be defined in and downloaded from the re- mote PC. Refer to the IT7200 Series Software User Manual for operation methods. • Refer to A.2 Built -in Waveforms...
This function with complex waveforms can help users to simulate grid disturbance, periodic power off and so on. This power supply needs to use the IT7200 Series Software to edit the List func- tion contents, and download the List files to local equipment. Then, the instru- ment can locally run the List function.
The Dimmer Function aims to adjust the light illuminance intensity by setting the phase angle and concealing the leading edge or trailing edge waveform. This IT7200 series power supply supports front and rear phase angle dimmer or speed adjustment test to verify whether the product has potential quality prob- lem when the end user uses dimmer or the speed controller.
The surge/trap function can only be used under the AC Mode. 4.8.5 Digital I/O Function The IT7200 series power supply supports digital I/O function, which can be used for controlling and monitoring power supply output. For position, see 1.4 Rear Panel at a Glance.
4.10.2 Save and Recall Operations IT7200 series power source can save up to 10 common parameters in nonvola- tile memory (No. 0 to No. 9) for user to recall conveniently. The contents stored in each group include: output mode(AC/DC), voltage setting value(AC), voltage setting value(DC), OCPrms, frequency setting value and phase angle.
