Product Information "Electronic High-Speed DC Load | IT8700P+ Series"

ITECH IT8700P+
Electronic High-Speed Multi-Channel DC Load
Ultra-Fast Dynamics up to 12 A/µs, Flexible Power Scaling via 16-Channel Master/Slave Parallel Operation

System Architecture and Operating Principle
The IT8700P+ series is a multi-channel DC electronic load with high-speed control, designed as a modular test system. The DC load system consists of a mainframe and plug-in load modules that are synchronously controlled. IT8700P+ modules are compatible with existing IT8700P systems and can be operated together within the same chassis. The architecture supports master-slave parallel operation and enables simultaneous testing of multiple outputs or multi-output DC power supplies.

Dynamic Load Simulation and Control Performance
This electronic DC load is designed for test applications requiring fast load transients and stable control behavior. The high control speed allows controlled current loading without overshoot and supports reproducible results in dynamic tests. Multiple current ranges enable precise load simulation in both low-current and high-current operating regions, making the DC load suitable for functional, efficiency, and standby testing.

Applications in Development, Production, and Quality Assurance
Typical applications of the IT8700P+ include testing of batteries, supercapacitors, fuel cells, as well as AC-DC and DC-DC power supplies. Power supplies with multiple outputs can also be tested synchronously using the multi-channel DC load. With integrated communication interfaces and support for the SCPI protocol, the system is well suited for automated test systems, end-of-line testing, and structured quality assurance in industrial environments.

Safety, Protection Functions, and System Integration
Comprehensive protection functions support safe operation in daily test environments. The modular system structure simplifies integration of the DC electronic load into existing test setups and provides high investment protection through flexible expandability as test requirements grow.
