Product Introduction

Electrical characteristics
Input voltage range: Typically, this type of power supply may support a wide range of inputs, commonly ranging from AC 90V to 264V, to adapt to the mains input in different

regions and application scenarios, and can also operate stably in environments with large voltage fluctuations.

Input frequency: generally 50Hz-60Hz, can adapt to common AC power frequencies.

Efficiency: The efficient AC-DC power conversion efficiency may be around 90% -95%, which can reduce energy loss, lower heat generation, and improve energy utilization

efficiency.

Power factor: The power factor correction function can achieve a power factor of 0.95 or above, reduce harmonic pollution to the power grid, and improve the effective utilization

of electrical energy.

Ripple and noise: The output ripple voltage is usually controlled at a low level, for example, at 24V output, the peak to peak value of the ripple voltage may be less than 50mV,

ensuring stable and pure DC power supply for the load.

physical characteristics
Size: It may adopt a standard 1U or 2U rack design for easy installation in standard cabinets. The width is generally 19 inches, and the depth may be between 300mm and 500mm

depending on the specific design.

Weight: Due to its high power output, it contains a large number of electronic components and heat dissipation parts inside, and its weight may be around 5kg-10kg.

Shell material: Metal shells, such as aluminum alloy or cold-rolled steel plates, are usually used, which have good heat dissipation and electromagnetic shielding properties, can

protect internal circuits from external electromagnetic interference, and also prevent internal electromagnetic radiation leakage.

Protection function
Overvoltage protection: When the output voltage exceeds the set safety threshold, such as 28V, the power supply will automatically cut off the output to protect the load equipment

from damage caused by excessive voltage.

Overcurrent protection: When the output current exceeds the rated current of 229A, such as reaching 250A, the power supply will trigger an overcurrent protection mechanism to

limit the output current or cut off the output, preventing damage to the power supply and load due to overcurrent.

Overheating protection: There is a temperature sensor installed internally. When the internal temperature of the power supply reaches a certain value, such as 85 ℃, it will

automatically reduce the output power or cut off the output. After the temperature drops, it will resume normal operation to prevent component damage caused by overheating.

Short circuit protection: When a short circuit occurs at the output terminal, the power supply can quickly detect and cut off the output, avoiding damage to the power supply and

other equipment caused by the short circuit current. After the short circuit fault is eliminated, the output can be automatically restored.

Application scenarios
Industrial automation: It can be used to drive large motors, programmable logic controllers (PLCs), industrial robots and other equipment, providing stable power support for

various devices on industrial production lines to ensure the smooth progress of the production process.

Data center: provides reliable power supply for servers, storage devices, network switches, etc., meets the data center's demand for high-power and high stability power supply, and

ensures the security of data storage and transmission.

Communication base station: supplies power to the RF module, baseband processing unit, transmission equipment, etc. of the base station, ensuring stable transmission and

reception of communication signals, and guaranteeing the coverage and quality of the communication network.

Medical equipment: Suitable for medical devices such as CT scanners, magnetic resonance imaging (MRI) equipment, large medical monitoring systems, etc. that require

extremely high power stability and safety, providing reliable power guarantee for medical diagnosis and treatment.
