WB Trans

We will design and manufacture according to your wishes from 80VA to 2700VA. (The photo is an example, 300VA type)

The WB Trans (coil bobbin type transformer) offers approximately half the volume compared to EI type transformers of the same capacity, and is thin, lightweight, energy-efficient, and available at a lower price. Our company started handling this product 20 years ago, and we conduct everything from design to production in-house, which allows us to offer competitive pricing. We take pride in having the highest cumulative production numbers in the industry. Leveraging the know-how we have developed, primarily for medical equipment and gaming devices, we respond to customer requests with small lot sizes and short delivery times.

WB Trans CE/UL/CSA compliant WECC/WECA series

WB Trans CE/UL/CSA compliant WECC/WECA series

This is a single-phase isolation transformer designed in accordance with EN61558 and IEC61558 based on the European Low Voltage Directive.

It is classified as a "transformer without a short-circuit protection circuit with double insulation" as an insulated transformer and a safety insulated transformer. For various European countries, CE marking is possible, and a Technical Construction File (TCF) is attached. UL adopts individual certification, and it has obtained UL5085 and CSA. It is standardly used as a power transformer for automotive equipment. ■ Insulation class: B.H. ■ Standards: EN61588 (IEC61558)/UL5085/C22.2 ■ Model: WECC-xx-UL-yzw / WECA-xx-UL-yzw (xx and yzw will contain numbers or letters) ■ Capacity: 100VA ~ 2.5kVA ■ Voltage: Primary side (P) below 600V (please specify your desired voltage) Secondary side (S) below 600V (please specify your desired voltage)

WB Trans

WB Trans

The coil bobbin and iron core are finished as an integrated structure, achieving high insulation performance and precise dimensional shape.

The "WB Transformer" is a newly conceived transformer that incorporates a no-cut iron core into a newly developed coil bobbin. We have developed a coil bobbin and an iron core winding device, achieving efficiency and stability in the processes of winding, insulation treatment, and iron core incorporation. It is an ecological transformer that promotes resource conservation and energy efficiency. 【Features】 ■ Compact, lightweight, and thin ■ High reliability ■ Fully utilizes iron core performance ■ No cuts or gaps in the iron core ■ Uses a coil bobbin *For more details, please refer to the PDF document or feel free to contact us.

WB Trans JEC compatible WT series Domestic use only type

WB Trans JEC compatible WT series Domestic use only type

This is a slim, lightweight cost-performance model. It is designed based on the JEC-2200.

It has the function of insulation and voltage boosting/reducing for single-phase circuits. Input and output can be connected not only through a terminal block but also through lead wires and connectors. The external shape is basically the same as WECA (vertical) / WECC (horizontal). ■Applicable standard: JEC-2200 ■Insulation class: B.H. ■Capacity: 100VA to 2.5kVA ■Voltage: Please specify the desired voltage for the primary side (P) Please specify the desired voltage for the secondary side (S) ● Explanation and precautions regarding inrush current ● WECC, WECA, and WT transformers use high-performance electromagnetic steel plates (0.2mm) and are designed with a significantly higher magnetic flux density compared to transformers using standard EI cores. On the other hand, the inrush current during excitation is larger, so when replacing with the current transformer, there is a possibility that the overcurrent protection device on the primary side may malfunction. If the protection device on the primary side is the same as the rated current, the likelihood of malfunction becomes very high, so it is necessary to either adopt a product designed to suppress inrush current or increase the rated interrupting current value of the protection device. Since measures against inrush current depend on the compatibility with the protection device, please contact our technical department for special designs and other inquiries.
