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.

Principle of transformers

Principle of transformers

Composed of two windings independent of the iron core! Here is an introduction to the principles of transformers!

I will introduce the principles of a transformer. A transformer consists of a core made of iron and two independent windings. The winding connected to the power source is called the primary winding, and the winding connected to the load is called the secondary winding. When an alternating voltage is applied to the primary winding (P), a current flows through it (referred to as the excitation current), which generates a magnetic flux within the core. This change in magnetic flux induces a voltage in the secondary winding (S), and the induced voltages V1 and V2 in the primary and secondary windings are determined by the ratio of the number of turns in the primary winding N1 to the number of turns in the secondary winding N2. When a voltage is applied to the primary winding, a voltage proportional to the number of turns is induced in the secondary winding, and by changing N1 and N2, the ratio of the primary voltage to the secondary voltage can be arbitrarily altered. *For more details, please refer to the PDF document or feel free to contact us.*

Classification by the structure of transformers

Classification by the structure of transformers

Introducing the structure of "external iron type transformers" and "internal iron type transformers"!

I will introduce the classification of transformers based on their structure. Transformers are constructed using a combination of a core and windings. "External core transformers (including wound core types)" have two or more magnetic circuits surrounding the windings. They have an appearance where the core is located outside the windings. "Internal core transformers" have a single magnetic circuit with windings arranged around it. They have an appearance where the core is located inside the windings. *For more details, please refer to the PDF document or feel free to contact us.

Insulation type of transformer

Insulation type of transformer

The temperature rise limit is defined by the insulating materials used! An introduction to the types of insulation for transformers.

Transformers are reliable and long-lasting devices, but prolonged use can lead to deterioration of the winding insulation and insulating materials due to temperature effects. They are also significantly affected by the ambient temperature in which they are used. To ensure safe long-term use, temperature rise limits are established based on the insulating materials used, and each type of insulation material has its own specified temperature rise limit. The maximum allowable temperature, under rated conditions, is the temperature rise limit of the insulation type plus the reference ambient temperature (40°C). When installed and used in control panels, it is generally necessary to consider that the internal temperature rise of the panel can be 5 to 10°C. *For more details, please refer to the PDF documentation or feel free to contact us.
