Disaster prevention and BCP measures [hospitals, clinics] for emergency power supply! Mobile storage system.

Disaster prevention and BCP measures [hospitals, clinics] for emergency power supply! Mobile storage system.

We recommend securing a minimum power supply in preparation for disasters and unexpected power outages.

"CUBOX" is a portable power storage system that can be easily used with the push of a button. It can supply power for approximately 30 hours as a backup power source for office buildings (about 10W for communication devices, about 70W for information terminals, and about 20W for lighting fixtures). *For CUBOX 3.3kWh model. Traditionally, the mainstream approach to disaster prevention and BCP (Business Continuity Planning) measures has been the use of generators, but the assumption that "generators will definitely operate" is being reevaluated. In fact, during the Great East Japan Earthquake, about 30% of generators failed to operate due to safety device activation and maintenance issues caused by the earthquake. Backup power sources are necessary to maintain the functionality of hospital facilities. [1] Emergency backup power for critical equipment such as pharmaceutical refrigerators [2] Backup power for communication devices as a means of communication among staff [3] Backup power for ward lighting fixtures As part of disaster prevention and BCP measures, there have been implementations in over 50 municipalities and more than 30 hospitals to date. <Features> - Does not emit carbon monoxide or unpleasant odors, making it usable indoors. - Designed for quiet operation, allowing use at night. - Provides a better waveform (pure sine wave) than commercial outlets, making it suitable for precision equipment. - Easy maintenance. - Utilizes reliable Japanese-made lithium-ion batteries and power supplies.

[Switching Power Supply Solutions and Proposal Examples] Miniaturization of Products

[Switching Power Supply Solutions and Proposal Examples] Miniaturization of Products

Achieved a power density of 2.75 cm³/W through the utilization of PWSB! A case that contributed to the miniaturization of products.

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.
