The impact of temperature on the lifespan of DIN rail power supplies.

The impact of temperature on the lifespan of DIN rail power supplies.

High-efficiency power supplies generate low heat! If the full-load efficiency is high, space-saving designs become possible.

For system engineers, securing a reliable power supply that can be used for a long time is extremely important. Using a power supply that is prone to failure leads to increased costs in terms of effort, expenses, and time. PULS GmbH (Germany) is working on extending the lifespan and ensuring high reliability of power supplies with its unique cooling design. 【Features of the Cooling Design】 ■ Low heat generation due to high efficiency of the power supply ■ Optimization of heat dissipation, which is essential for longevity ■ Importance of proper component placement ■ Thermal imaging camera showing the heat generation status of the power supply unit ■ Trivia about power supply efficiency and temperature We would appreciate it if you could download the PDF file for more details. If you have any questions or concerns, please feel free to contact us.

[Switching Power Supply Solutions and Proposal Examples] Improvement of Standby Efficiency

[Switching Power Supply Solutions and Proposal Examples] Improvement of Standby Efficiency

Improvement from 70% to 85% at 100V input! Introducing examples of standby efficiency improvements.

We would like to introduce a case study of solutions and proposals for "switching power supplies." The issue we are presenting this time is the need to improve standby efficiency due to high standby power consumption, which falls under regulatory frameworks such as North America's Energy Star and Europe's Blue Angel. When the input voltage is high, the losses of internal circuit components during steady state increase, so we were able to achieve improved standby efficiency through optimizing the efficiency of the power-consuming circuits and the components. 【Case Overview】 ■ Challenge - High standby power consumption requires improvement in standby efficiency due to regulatory compliance. ■ Result - Achieved improved standby efficiency. ■ Product - Switching power supply. *For more details, please refer to the related links or feel free to contact us.

[High Voltage Power Supply / High Voltage Transformer Solutions and Case Studies] Achieving Miniaturization

[High Voltage Power Supply / High Voltage Transformer Solutions and Case Studies] Achieving Miniaturization

Improved reliability! A case study demonstrating miniaturization achieved through open transformers to cast transformers.

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.

Power supply for server UPS backup during electrical equipment regular inspections.

Power supply for server UPS backup during electrical equipment regular inspections.

It has been implemented in the data center and adopted as a power source for server UPS backup during regular electrical equipment inspections.

The "HPP-2000/HBB-1000" is an off-grid power supply that can be used in the same way as a power outlet in places without electricity. In the data centers where it has been implemented, it allows for power expansion according to power outage times, enabling continuous use for each rack. Additionally, since it can adjust power consumption and voltage, it is also used as a power source during trial runs of servers before installation in the data center. *For more details, please download the PDF or feel free to contact us.*
