The ECAT E103, E501B, E503 and E4554 by Thermo Fisher Scientific / Keytek are designed to test to a variety of immunity standards requiring three phase surge, EFT, & ringwave. This Thermo Fisher Scientific EMI immunity test equipment comes with an A2LA accredited calibration and free technical support included with rental. This rental is a combination of the ECAT E103 control unit, E501B, E503 and E4554 modules.

This Thermo Fisher Scientific / Keytek EMC immunity generator provides single port testing and allows changing tests modes without switching off power to the equipment under test (EUT). This helps testing with to be conducted efficiently without re-initializing the EUT between tests. The ECAT, E501B, and E503, can be rented individually or in combination with the ECAT E103. 

This ECAT system is designed to test EN/IEC 61000-4-5, EN/IEC 61000-4-12, ANSI/IEEE C62.41, ANSI/IEEE C62.45 and many other EMC standards. The modular system of this Thermo Fisher / Keytek product is upgraded to meet the latest requirements of the IEC standards. The E103 and E501B, E503, E4554 combination can be controlled via front panel or through computer using Keytek software.
