AC/DC Converters

An AC/DC converter (also known as an AC/DC power converter) takes an AC input and converts it to DC, while maintaining smooth operation of the power source. The technology is widely deployed in automotive, industrial and consumer applications. With advances in digital technology, AC/DC converters can now be manufactured with greater efficiency and control.

The HRPG-450-48 AC/DC converter is a compact, cost-effective solution for many applications. It is a 48V power source outputting 6A continuous current with up to 10A peak current. It has a wide input voltage range of 85-295 VAC, making it suitable for mains applications. The unit is highly efficient, boasting an active power factor-correction (PFC) circle of greater than 99.5%. It is suitable for use with inductive and capacitive loads.

The HRPG-450-48 is designed to be a drop-in replacement for many legacy designs. It is highly reliable and efficient, with an output ripple and noise of less than 1% and a low standby power consumption of 2W. The unit has overload, input overvoltage and short-circuit protection, as well as an input surge immunity of 2kV. It can operate in an ambient temperature range of -20°C to +60°C.

The unit operates according to the principle of active-bridge rectification. This is where an active switch is connected in series with a diode bridge and the AC-load voltage is monitored. When a switch in the bridge loop detects a higher voltage, it is opened and the load receives energy from the other end of the bridge. The power supply is actively regulated to maintain the output DC voltage, as well as a low line-input current distortion.

The HRPG-450-48 has a wide range of applications in consumer, industrial and automotive electronics. It is particularly suited to LED lighting, solar inverters, telecom systems and other 24V applications. Its wide input voltage range makes it suitable for global use in multiple power sources, and its input power factor correction makes it possible to achieve greater efficiency in power saving applications.

In summary, the HRPG-450-48 AC/DC converter is an ideal choice for many applications in automotive, industrial and consumer electronics. Its active bridge rectification principle makes it highly efficient and reliable. It has a wide input voltage range, overload, input overvoltage and short-circuit protection, and is suitable for use with inductive and capacitive loads. Overall, the HRPG-450-48 is a cost-effective and reliable solution for many global applications.
