Yamanashi EMC Center

Test facilities for Emission and Immunity including large devices.

Accreditations:VLAC, BSMI, VCA

Our Open Air Test Sites (OATS) are ideal with no environment noise, actually making them cost-effective compared to anechoic chambers. Reserveation can be made both for emission and immunity testing simultaneously for long periods of time.

EMC testing for the large equipment and devices required high electric power supply is also possible, while our Open Field Test site enables testing for large construction machinery.

The testing according to the technical requirments for "REESS* charging mode" including the outlet to electric vehicle can be provided here. Yamanashi EMC Center is the first EMC laboratory in Japan which satisfies both REESS and non-REESS type approvals.
* REESS: Rechargeable Energy Storage System
