⚫ Always use test lines provided by ITECH to connect the equipment. If test lines from other factories are used, please check that the test line can withstand maximum current.
Getting Started Power Switch Introduction The POWER switch knob of the IT7800 series power supply is on the left side of the front panel. The user can turn ON the power by 90° clockwise. Turning the POWER Switch On Check that the power cord is connected properly.
Under the Multi-channel phase, the power supply works as a single phase power supply and have three channels. The multi-channel function of the IT7800 series allows users to test 3 independent DUTs at the same time without adding additional hardware configuration.
Operation and Application 4.2 Select the Output Mode The IT7800 series has four output modes: AC, DC, AC+DC, DC+AC. It not only provides pure AC/DC output, but also can use AC+DC and DC+AC output modes to realize "AC output plus DC bias" And "DC output waveform with ripple", which cover a wider range of applications.
4.4 Auto-range Function IT7800 series power supply can achieve the combined output of multiple voltage and current at a fixed power. Single power supply can meet different DUT tests with high voltage low current or high current low voltage, at the same time, because the output of voltage and current is controlled by the limit power, it will show the switching of voltage and current auto ranging.
30V or more is required for 100% current output. 4.6 Current Limit Mode and Power Limit Mode The IT7800 series power supply defaults to constant voltage CV output mode. The output voltage can be set in main interface.
Sweep function. 4.8 Power Amplifier The IT7800 series regenerative grid simulator can be used as a power amplifier to complete power hardware in the loop (PHIL) applications for microgrids, energy storage and new energy vehicles. The digital I/O or a standard suite of analog signal can be input via an external analog interface (optional) and then amplified without distortion to a real power waveshape.
Operation and Application 4.10 Polyphase Function The IT7800 series power supplies implement the frequency-locked and phase- locked function between power supplies through the digital IO interface or System bus interface, which achieve 6 phase& 12 phase power output. This power supply provides two ways to achieve multi-phase functionality: One is to connect the System bus interface between instruments directly ⚫...
Operation and Application 4.11 Standard IEC Regulations IT7800 series AC/DC power supplies provide standard test curves in accordance with IEC 61000-4-11/4-13/4-14/4-28 regulations. It can be invoked directly by the user when testing IEC compliance tests. This function provides both the test curve that meets the standard requirements of regulations and the curve customization function.
5.1.2 Set the communication interface This menu item is used to set the communication information between instrument and PC. The standard communication interfaces for IT7800 series power supply are USB, LAN and CAN. You can also select the non-standard interface GPIB or RS-232 based on personal requirement.
Press [Enter] to recall the parameters. 5.6 Protection Function IT7800 series source includes the following protection functions: overcurrent protection (Current RMS protection, Current peak protection), voltage limit protection and over-temperature protection (OTP).
System-Related Functions 5.7 Screen Capture Function IT7800 series power supply has the screen capture function. Insert the USB disk into the USB interface of the front panel, and press [Print] on the front panel to capture and save the current screen into the USB disk.
After the instrument is restarted, the screen shows that the instrument is working in single mode. 5.12 Remote Measurement Function The IT7800 series power supply supports two connection methods: Local measurement and Remote sensing. The remote sensing is used for maximizing measurement accuracy. (Refer to 2.5 Connecting Test Lines).
5.14 Analogue Function (Ext-Program) (Optional) The interface expansion slot provided on the rear panel of the IT7800 series. This function is not standard with the instrument and is optional for users. When the interface card selected by the user is RS232+Analog interface (IT- E177), the analog interface can realize the external analog function.
This chapter describes the characteristics and operations of the basic metering function of IT7800 series source. IT7800 series source has rich functions of basic metering of electric energy and can accurately measure the parameters such as Vrms, Irms, Ipeak, Idc, CF, PF.
DC current 6.2 Oscilloscope Mode IT7800 series source has the function of displaying the waveform based on sampling data. The user can select to display or hide the voltage and current waveform of the input unit. Only the necessary waveform is displayed, which can facilitate observation.
