It includes transportation and industrial requirements, two-wheel/three-wheel electric vehicles, electric hand tools, weeders, drones, and unmanned handling robots, etc.

Energy storage systems play a crucial role in smart grids. Main applications include:
• Power regulation: Provide electricity during peak demand and store it during low demand to balance the load.
• Grid stability: Offer fast-response power support for sudden changes in demand.
• Renewable energy integration: Store electricity generated from solar and other renewable sources to improve energy utilization. FSP's LightUp Series inverters combined with battery systems, or the all-in-one mobile storage system EnerX 3000, effectively integrate solar generation and storage for optimized energy management and improved smart grid performance.

In energy storage systems, common units include:
• Power: Measured in watts (W) or kilowatts (kW), indicating the output capacity of the power conversion system.
• Energy: Measured in watt-hours (Wh) or kilowatt-hours (kWh), indicating the total energy stored in the battery.
• Capacity: Measured in ampere-hours (Ah), representing the amount of electric charge the battery can store.
For example, the EnerX 3000 mobile storage product has a rating of 3kW/2.5kWh, meaning it provides up to 3 kW of output and stores 2.5 kWh of energy.

FSP new energy storage system products focus on the development of distributed energy storage systems that are applied on the power load end to provide real-time backup functions, and avoid the impact of power outages caused to the grid by accidents.

The application fields include home use, residential and commercial complex, industrial plants or microgrids, etc. 
For the applications mentioned above, FSP provides 10 kW to 100kW level energy storage system solutions, and takes the solar output voltage range and power feed/self-use requirements into consideration to build the electricity consumption and output power required for backup or emergency power supply.

The requirements of AC power are Single Phase, Split Phase and Three Phase.
The voltage of a single set of battery is 48V/100Ah, and can be expanded up to 10 sets. 
Power supply sequence: PV has highest priority, then city mains, and then battery backup.

Flex ATX form factor (hereinafter referred to as Flex) is a power size designed for small industrial control computers. 150*81.5*40mm, some users call it small 1U. It is currently widely installed in network switches, firewalls, and related products.

A2: Since the usage environment of industrial computers are different from the environment of general home/office computers, therefore, the power’s: 
1. Working temperature is 0~50 degrees Celsius
2. They operate 24-hours a day without interruption, therefore, the cooling fan needs to operate for long periods of times, so ball-bearing fans must be used

After eliminating the A2 problem, it seems that it can in the short-run. However, the life cycle of the IPC system vendor’s products must be at least 5 to 10 years, and the life cycle of the retail market powers is only two to three years and cannot satisfy the logistical requirements of IPC SE; therefore, it is not suitable.

CRPS is short for Common Redundant Power Supply; it is a power module specification applied in the server field defined by Intel together with many leading companies in the industry. The specification focuses on the demands for digitalization, high efficiency, high density, compact size and high stability; it is agreed by many system vendors and widely adopted in the industry.

Although CRPS is a shared specification, the different companies may have different applications and designs in terms of detail; therefore, it cannot be used together with CRPS power products from other companies.

 FSP has complete plans for this; please refer to this.

Standby Power refers to the electric power consumed by electronic and electrical appliances while they are switched off or in a standby mode.

In non-peak power usage environments, the power selection of Open Frame PSU is determined by the power required by the system, the temperature inside the system, and the wind flow provided by the system. 
Referring to the product specifications of FSP260-P35-A12, when the power is operating under an ambient temperature of -20℃~50℃, the output power is 260W @ 18.4 CFM; and under the condition with no wind flow, it is only 150W @ Convection. If the temperature of the PSU’s working environment exceeds 50℃, you must refer to the derating curve of the power and reduce the output power as the ambient temperature rises in order to ensure the power will not enter over-temperature protection or even get damaged from overheating. If it is a peak power usage environment, please contact our business unit to have further discussions.

Choosing a PSU usually starts with selecting the form factor. Standard desktop systems commonly use ATX, while compact builds may opt for SFX or TFX. Next, you can choose the efficiency rating and determine the required wattage based on the components used.

ATX 3.0 is a desktop Power Supply Design Guide that Intel updated in 2022, in which new versions of design specifications such as CPU 12V current configuration and Peak Load requirements are included.

ATX 3.1 is a desktop power supply design guide updated by Intel in September 2023. It references the PCIe 5.1 specification and updates the 12+4 pin 12VHPWR connector to 12V-2x6.
