About This Product

As communications and network systems, which form the core of the information society, are developing rapidly, a stable supply of high-quality, highly accurate DC power is essential for base station communications equipment and switching equipment necessary for mobile communications. Based on the power supply circuit technology and stabilized power supply development know-how cultivated over many years, Sanken Electric's DC power supplies are used in a wide range of applications, from power and power generation control and plant control to public essential lifelines such as satellite base stations, traffic monitoring systems, and disaster prevention radio. In particular, units that use the latest switching method achieve top-class space savings through high efficiency and miniaturization. In addition, with an energy-saving design that thoroughly suppresses input harmonic currents that cause large power losses, it will make a major contribution to the multimedia era, where power consumption is expected to increase in the future.

■"Harmonic suppression" is an essential issue in the information society.

Communication and network systems, which form the core of our highly information-oriented society, have undergone dramatic development over the past few years. As demand for these communication devices increases, the importance of a stable power supply using DC power supplies has become increasingly important. However, the DC power supplies that have been mainstream until now contain large amounts of harmonic current due to their capacitor input circuits. Harmonics pose major problems, such as damaging power systems and requiring larger power receiving and power generation equipment for emergency backup. In order to regulate these harmonics, the Agency for Natural Resources and Energy has established guidelines, and harmonic suppression is an issue that the entire industry must address immediately. Sanken Electric's newly introduced "rectifier unit with PFC" is a unit for soft-switching DC power supplies that is responsive to the trends of the times. Adopting a PFC circuit suppresses harmonics and achieves high power factor and efficiency. It has an energy-saving design that significantly eliminates power loss, and is compact. We will respond to a variety of needs in the multimedia era, where power consumption is expected to increase further and power supplies with larger capacities are expected.

■Sanken Electric's rectifier unit with PFC

・Significantly suppresses harmonic current. ・Realizes efficiency of 92.5% and power factor of nearly 1.0. ・Low noise design compatible with VCCI type 1. - Approximately 30-40% smaller and lighter than our conventional products.
