We would like to introduce a case study of the "Magnet Roll" handled by Power Supply Technology Co., Ltd. The issue we are presenting this time is the need to "achieve strict energy-saving goals for the multifunction printer." To achieve energy savings, it is necessary to reduce the rotation torque on the developing machine side, and magnetic characteristics (magnetic waveforms) that can reduce the load are essential for this reduction. Therefore, by utilizing PST's unique method of individual piece molding and individual magnetization control technology, we realized a magnetic waveform suitable for energy saving, contributing to the achievement of our customer's goals. Furthermore, this also contributed to an extended lifespan due to the reduced load. [Case Overview] ■ Challenge - Achieve strict energy-saving goals for the multifunction printer ■ Results - Realized a magnetic waveform suitable for energy saving - Contributed to an extended lifespan due to reduced load *For more details, please refer to the related links or feel free to contact us.

We would like to introduce a case study of a solution and proposal regarding the request to "miniaturize the set." In this case, the current situation involves the use of an open transformer, with high-voltage circuits such as rectifier circuits implemented on the circuit board. It was noted that miniaturization is difficult due to the need to secure the required insulation distance. To address this, we enhanced insulation and achieved miniaturization by encapsulating the transformer windings and high-voltage components such as the rectifier circuit in resin. Furthermore, the use of void-free resin encapsulation has also improved reliability. 【Case Overview】 ■ Challenges - Miniaturization of the set - Miniaturization is difficult due to the need to secure the required insulation distance ■ Results - Enhanced insulation and achieved miniaturization - Improved reliability through void-free resin encapsulation *For more details, please refer to the related links or feel free to contact us.

We would like to introduce a case study of a solution/proposal for the "switching power supply" that addresses the need to "reduce the size of the power supply for product miniaturization." To miniaturize the power supply, it is necessary to efficiently cool the heat generated by the power supply. However, if large heat sinks or cooling fans are added for cooling, the size of the power supply increases accordingly. Therefore, we changed the cooling method to conductive cooling using PST's unique product, the PWSB, applied to a metal enclosure. This allowed us to achieve a power density of 2.75 cm³/W and successfully miniaturize the switching power supply. 【Case Overview】 ■Challenge - To reduce the size of the power supply for product miniaturization ■Result - Achieved a power density of 2.75 cm³/W, successfully miniaturizing the switching power supply ■Product - Switching power supply *For more details, please refer to the related links or feel free to contact us.
