Product Overview

EMTEST UCS200N / EM Test UCS 200N

The EM Test UCS 200N Ultra-Compact Simulator for Automotive Transients unifies the capabilites of an EFT/Burst simualtor, a Micropulse simulator and the required coupling network into one box. The UCS 200N Transient Tester is equiped to meet all international and car manufacturer specifications from around the globe. The built-in coupling network ranges from 50A, up to 200A depending on the model / option specified. The built-in coupling network can be used and controlled by any unit of the LD 200N, VDS 200N and PFS 200N. For tests beyond standard's requirements the waveform parameters of the Micropulse generator can be varied in a wide range by means of the FreeStyle mode.

The EM Test UCS200N has the following specifications:
