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.

Three-phase to single-phase transformer. This transformer is a Japan domestic standard large-capacity transformer designed conforming to JEC-2200. This transformer is used when a single-phase load (one circuit) of considerably large capacity is to be obtained from a three-phase circuit by transformer wiring.

This transformer is a three-phase amorphous transformer designed based on JEC-2200 and JEM1310. Transformers using amorphous materials reduce standby power by approximately 1/6 to 1/8 compared to those made of silicon steel sheets. No-load loss (standby power) refers to the losses that occur continuously while in a receiving state. Since transformers are used for long periods, minimizing no-load loss (standby power) can lead to significant energy savings. An amorphous transformer that achieves a performance of 99.3% efficiency at a load factor of 20% (3φ50kVA model) demonstrates energy-saving effects across all areas, regardless of the load. = Amorphous Series = ■ Standards: JEC-2200, JEM1310 ■ Insulation Class: Class B, Class H ■ Rating: Continuous rating ■ Cooling Method: Dry self-cooling ■ Frequency: 50Hz / 60Hz ■ Capacity: 10kVA ~ 300kVA ■ Voltage: Please specify your desired voltage for the primary side (P) and secondary side (S).

■ Capable of manufacturing up to a maximum rated current class of 3000A. We propose optimal designs for the core (silicon steel sheets, Super E, amorphous, Finemet, powdered iron cores, ferrite) and coils tailored to the frequency range, including copper strips, litz wire, and single wire. (1) Considering the structure in terms of IP (Ingress Protection) ratings, we can also provide products that are resistant to harsh environments. (2) Compliance with international standards (IEC/EN/UL, etc.) is available. (3) Direct current superimposition characteristics will be measured. (4) Vibration testing evaluations will be conducted. (5) Slim design is possible. ■ Direct Current Superimposition Characteristics: When a direct current bias flows through an inductor, the permeability decreases as it approaches the saturation point of the magnetic material, resulting in a decrease in inductance value. This characteristic is referred to as direct current superimposition characteristics. The issue with this direct current superimposition current arises when a core with a higher permeability than air is used to achieve a small size with a large inductance. Since cores like iron have a permeability that is significantly greater than that of air, it is possible to achieve a small size with a large inductance.
