Flexible Module Matching

The IT8700P+ series adopts the design of interchangeable modules, which allows users to freely select different modules according to their needs, and can be mixed with the modules of the IT8700P series. Moreover, each load module and main control module unit has a high-performance microprocessor chip. The parallel architecture between them provides high test speed. The load modules are synchronously controlled by the system, and power supplies with multiple outputs can also be tested simultaneously.

High-speed dynamic mode

Power supplies often have high requirements for transient signals and dynamic response, in order to meet the development of increasingly high-speed power supply changes, the IT8700P + provides a high-speed, programmable dynamic timing control, single-module current rise and fall slope 12A/ μs, much higher than the previous generation of products, can be used for communications power supplies, intel graphics power supply of high-speed dynamic testing.

The dynamic test functions of the IT8700P+ series can be categorized into Continuous Mode, Pulse Mode and Flip Mode.

master-slave parallel mode

IT8700P + the same specifications between the modules to support the master-slave parallel connection, up to 8 parallel 16-channel, to 4800W, parallel synchronization of the beat difference of the maximum of about 4uS, parallel equalization accuracy of 0.1% + 0.1%FS. can be applied to a variety of specifications to be measured, the power to expand the very flexible, convenient for R & D laboratories, the utilization of equipment is also high. This master-slave parallel connection has an equalization mode to ensure that the dynamic performance is consistent with that of a single machine.

Three Current Ranges for Consumer Electronics ENERGY STAR Standards

The IT8700P+ current range has been increased to three levels for greater measurement accuracy, making it suitable for batteries and other items to be tested where current accuracy is critical. A third low-current operation and measurement range provides a test solution for the sleep, idle and standby modes required for Energy Star consumer electronics. This capability eliminates the need for complex test bench equipment. Suitable for all types of consumer electronics when accurate current setup and measurement at milliamp and microamp levels are required.
