Transformer inspection methods

Transformer inspection methods

Rich inspection content such as "pressure test" and "inter-layer dielectric strength test"! Introducing the inspection methods for transformers.

We conduct intermediate inspections, final inspections, and shipping inspections for transformers. In the "withstand voltage test," we check whether the insulation between the test subject and other parts maintains appropriate insulation capability. In addition to this, there are other tests such as "inter-layer dielectric strength test," "insulation resistance test," and other items tested during prototype production based on the validity of the design and customer requests. 【Inspection Contents】 ■ Withstand Voltage Test ■ Inter-layer Dielectric Strength Test ■ Insulation Resistance Test ■ No-load Current (Excitation Current) / No-load Loss (Iron Loss) ■ No-load Voltage *For more details, please refer to the PDF document or feel free to contact us.

[Custom Order Example] Slim OI Transformer Compliant with DIN Standards

[Custom Order Example] Slim OI Transformer Compliant with DIN Standards

Customization requiring delicate processing! Introduction of a case where we manufactured a transformer that fits into the customer's product.

We would like to introduce an example of a slim OI transformer that complies with DIN standards. We received a request from a customer who wanted to adopt a power transformer that fits within a 1 DIN size but was struggling with the height limitations of existing slim transformers. In response, our company further customized the well-regarded OI transformer, known for its slim design under 100W, to create a transformer that fits the customer's product. By utilizing the dead space of the O-shaped iron core to draw out taps, we achieved a slim design and size reduction. 【Custom Product Specifications】 ■ Size and Dimensions: 73mm × 50mm × 35mm ■ Voltage Specifications: Primary Voltage 100–200V / Secondary Voltage 100–200V ■ Capacity: 8–156VA ■ Applicable Standards: JIS-C6436 ■ Insulation Type: Class E ■ Products Used: Measurement equipment, disaster prevention equipment *For more details, please refer to the PDF document or feel free to contact us.

High-frequency transformer with controlled inductance tolerance for flyback transformer.

High-frequency transformer with controlled inductance tolerance for flyback transformer.

We can provide high-precision prototypes with short delivery times through cross-adjustment by processing! This transformer can accommodate from EPC17 to large cores.

We would like to introduce a case of a flyback transformer with controlled inductance tolerance. In the development of switching power supplies, we received a request to reduce the inductance variation of the flyback transformer and to conduct early practical evaluations of the transformer. Typically, inductance adjustments are made using processed products from ferrite core manufacturers or space materials, but there are challenges regarding delivery times and accuracy. However, our company, which owns grinding processing equipment, has overcome these challenges and was able to provide prototypes in a short time. Additionally, this transformer can accommodate sizes from EPC17 to large cores. 【Custom Product Specifications】 ■ Size and Dimensions: EER9.5 to PQ100 ■ Applicable Standards: UL1446 ■ Insulation Type: Class B ■ Products Used: Industrial equipment, medical devices, measuring instruments *For more details, please refer to the PDF document or feel free to contact us.
