Kitagawa Electric Co.,Ltd
We design and manufacture various transformers including transformers for medical instruments.
Our business involves various transformers as well as chokes and reactors. We have accumulated a wealth of experience in fields such as solar power generation and other next-generation energy, industrial control instruments, and semiconductor manufacturing instruments. We can provide reliable reactors by using our evaluation instruments. Our NEO series of medical instrument transformers realizes size reduction and light weight while maintaining high safety that meets international standards for medical instruments. We are also working to develop power supply parts that are required as a consequence of the recent trend for the frequency of power supplies to increase.
[Product description] Low loss High frequency loss in a reactor cannot be ignored in converters for industrial instruments because of the large load variation. We will propose a small-size, low-loss reactor by combining the coil structure and core material to support high frequencies and large ripple currents. Thin We developed this thin reactor by making full use of our know-how in the design and manufacture of special-sized cut cores. We will propose a shape that utilizes 120% of a limited mounting space, such as in-vehicle items, space-saving cubicles, etc. Assured performance Reactor power loss measurement by means of high-frequency current and heat running tests are possible using our original high-frequency reactor assessment system. We realize an optimal design for size reduction and weight reduction according to the measured values.
[Product description] Low loss and low heat generation The switching frequency in large-capacity converters has been shifting toward the high-frequency side. We have realized high efficiency and size reduction with our company’s specialty cut-core technology. This could not be obtained by a three-phase reactor with a non-directional electromagnetic steel core. Thin shape We developed a thin reactor by making full use of our know-how in the design and manufacture of special-sized cut cores. We will propose a shape that utilizes 120% of a limited mounting space, such as in-vehicle items, space-saving cubicles, etc. Assured performance Reactor power loss measurement by means of high-frequency current and heat running tests are possible using our original high-frequency reactor assessment system. We realize an optimal design for size reduction and weight reduction according to the measured values.
[Product description] Medical standard conformity We have received certification through TUV Rheinland Holding AG under the international standard for medical equipment IEC 60601-1 Third Edition. This provides safety and security assurance for the customer’s equipment, and it is also effective in reducing costs for safety standard applications and shortening the delivery period. Size-reduction Our product is smaller, lighter, and thinner compared to an EI core-type transformer. The capacity is reduced to about 70%, the weight is reduced to about 50%, and the height is reduced to about 60%. Custom-made design We also support the custom-made design and manufacture of transformers for medical instruments. We can support voltages, capacities, shapes, etc., which are not included in the NEO series. [Authorization/Certification] CB Certificate, IEC 60601-1 (3rd edition).
[Product description] High voltage and high frequency Our company manufactures transformers supporting high voltages up to 5 kV, and high frequencies up to 30 kHz. We can also conduct partial discharge tests at 30 kHz. Partial discharge-free We can manufacture highly reliable high-voltage transformers because there is no partial discharge, which influences the insulation performance reliability (partial discharge-free). Considering that partial discharge works as a noise source, our product is also suitable for the high-voltage portion of measuring instruments that require high precision.
[Product description] Optimal design The secondary side (S1, S2) of this transformer equipped with a center tap is well balanced by optimizing the design of the winding structure. It is an optimal high-frequency transformer for a full-wave rectification circuit. Low leakage inductance The leakage inductance of the transformer is low, so it is possible to suppress switching power supply loss. High-frequency heat-running test Heat running tests can be conducted for this high frequency transformer. This is done using the electric power unit and load equipment that we independently developed for high-frequency transformer evaluation in addition to various high-frequency measurement instruments. We will conduct product evaluation in conditions matching (or close to) the specifications of the customer.
