Key Features
The following introductions of Chroma ATS show some application for PV Inverters. It is a customized system.
The Chroma 8000 ATS is equipped with optimized standard test items for PV inverters (the Unit Under Test), It meets IEEE1547, 1547.1, UL1741, GB/T 19939, NB/T 32004, CGC/GF004/GF035 preliminary test requirements. The user is only required to define the test conditions and specifications for the standard test items to perform the test.
Optimized Test Items
The optimized test item covers 5 types of power supply test requirements. The Output Performance test verifies the output characteristics of the UUT. The Input Characteristic test checks the UUT input parameters. Timing & Transient tests the timing and transient states during protection. The Protection TESTS trigger and test the protection circuit, the Special Test provides means to test the most sophisticated UUT when unique test routines are needed.
