More InfoQuote

The Chroma 8491 ATS is equipped with optimized standard test items for LED driver testing (lighting). The user is only required to define the test conditions and specifications for the standard test items to perform the test.

The optimized test items cover 6 types of power supply test requirements. OUTPUT PERFORMANCES verifie the output characteristics of the UUT. INPUT CHARACTERISTICS check the UUT input parameters. REGULATIONS test the stability of UUT under varying line-in and loading changes. TIMING & TRANSIENT test the timing and transient states during protection. PROTECTION TESTS trigger and test the protection circuit, the SPECIAL TESTS provide means to test the most sophisticated UUT’s when unique test routines are needed.
