1. Qhov ua rau ntawm EFT/burst immunity test (IEC/EN 61000-4-4)
Hloov cov hloov pauv (kom txiav tawm inductive load, relay hu bounce, thiab lwm yam) feem ntau cuam tshuam nrog lwm yam khoom siv hluav taws xob thiab hluav taws xob hauv tib lub voj voog. Hom kev cuam tshuam no yog siab amplitude, luv sawv-lub sij hawm, siab repetition npaum li cas thiab tsawg zog.
2. Lub hom phiaj ntawm EFT/burst immunity test (IEC/EN 61000-4-4)
Txhawm rau tsim kom muaj ib qho kev ntsuam xyuas zoo rau kev ntsuas kev ua haujlwm ntawm cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob fais fab chaw nres nkoj, teeb liab, kev tswj, thiab cov chaw nres nkoj hauv av thaum raug hluav taws xob nrawm nrawm cuam tshuam.
