Are you having trouble with the delivery date of the transformer?

Are you having trouble with delivery deadlines? Would you like to request alternative support from JPC?

Let's request an alternative from JPC to resolve the delivery issues with the transformers. - We have our own purchasing routes for unique core materials, and there is a possibility of obtaining materials that take time to acquire from other companies. - Additionally, there may be cases where we have standard stock of equivalent core materials from other companies that are delayed. - Our partner factories are fully managed by our own company, allowing for short lead-time production. (The partner factories are 100% our business.) - As a transformer specialist manufacturer, we can respond quickly from design and prototyping to estimation and mass production.

[On-Demand Seminar] EMC and Wireless Virtual Witness Testing Service

In this seminar, we will briefly explain the virtual witnessing examination while introducing actual exam videos.

In recent years, the demand for wireless and EMC testing has surged due to the wirelessization of products, the electrification and EV transformation of automobiles, and the electronicization of onboard devices. As it has become urgent to conduct conformity tests for the necessary standards, we have launched a virtual witnessing test service to make conformity testing more accessible. Traditionally, in witnessing tests, customers were required to visit the testing facility to set up tests and confirm the operation of the test subject devices. However, with the virtual witnessing test, customers can now participate in the witnessing tests from their own devices by combining various cameras, such as smart glasses, with a teleconferencing system. Additionally, we will also introduce applications for commissioned testing, not just witnessing tests.
