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.
