Switching power supply 300W 3.3V 90A HRP-450-3.3

High-efficiency switch-mode power supply

The HRP-450-3.3 power supply is a solid and reliable power source designed for applications requiring a stable 3.3V voltage. The device is characterized by a power of 300W and an output current of up to 90A, making it an ideal solution for a wide range of devices and systems. The use of active power factor correction (PFC) translates into higher energy efficiency and minimization of interference in the power grid.

Construction and protection

The power supply is equipped with a number of protections that protect both the unit itself and the devices connected to it. These include: short-circuit protection, overvoltage protection, overload protection, and thermal protection. A built-in fan provides effective cooling, maintaining optimal operating temperature even under heavy load. The ability to adjust the output voltage in the range of +/-15% allows for precise adjustment of the power supply parameters to the specific needs of the application.

Applications and standards

The HRP-450-3.3 power supply finds application in many fields, such as industrial automation, monitoring systems, audio-video equipment, and all kinds of applications requiring stable and reliable power. The device meets a number of standards and has certificates confirming its safety and quality. It is designed to operate at temperatures from -30°C to +70°C, making it suitable for use in harsh environmental conditions. Thanks to its high energy efficiency and solid construction, this power supply is an investment for years to come – the manufacturer offers as much as 5 years warranty.
