PR25

The PR25 converter is a 3-phase AC-DC converter designed to convert AC voltage from a power grid to DC voltage of adjustable range. It is widely used as the main power unit in various industrial and domestic applications. For example, it is used for providing power to media converters, Ethernet switches, IP phones, home network routers, and 3-phase motor drives.

The PR25 converter is built with a central control panel containing a digital signal processor (DSP), four power modules, four rectifier bridges, two capacitors, and two IGBT rectifying devices. The power modules control the voltage levels of incoming and outgoing signals, while the rectifier bridges and IGBT rectifying devices are used to convert AC to DC. The capacitors are used to store energy and to stabilize the voltage during the input and output phases.

The PR25 converter is mainly composed of a main control board and a power module. The main control board has an Ethernet interface for receiving the power signals, and a DSP for controlling the conversion of power. The power module then processes the signals coming from the DSP to adjust the output voltage level. It also contains two IGBT rectifying devices for controlling the conversion of AC to DC.

The PR25 converter works by measuring the input AC voltage using the main control board’s digital signal processor. The DSP then adjusts the current and voltage levels of the PR25 converter to convert the AC power into DC power. After the conversion, the output voltage can be adjusted by the power module to the desired level. Besides, the capacitors installed in the PR25 converter can also provide a stable voltage level.

The PR25 converter is capable of operating in a wide voltage range, from 12 VDC to 240 VDC. It can also handle a peak power of up to 20 kW. This makes it perfect for applications needing a high power capacity, such as industrial motor drives. Furthermore, the converter has a maximum power efficiency of 97% and an ambient temperature range of -20 to 70°C.

In summary, the PR25 is a state-of-the-art converter perfect for industrial and domestic applications. It can convert AC voltage from a power grid to a DC voltage of adjustable range and operate in a wide voltage range. Furthermore, its maximum power efficiency and low temperature range make it highly reliable and cost-effective.
