250-1500VDC Wide-input Miniature DC/DC Converter for Renewable Energy - PV40-29BxxR3

MORNSUN launched the 3rd generation DC/DC Converter PV40-29BxxR3 series for PV, energy storage, or other renewable energy industries. The R3 series are highly cost-effective, high-quality, safe, and reliable power solutions, their dimensions have been reduced by 80% than PV40-29Bxx series but with better performance. They also support 1700VDC high transient voltage for 30s, a wider operating temperature range, and are designed to meet CSA/CE/UL standards. Furthermore, they provide multiple protections, multiple packages, and a 3-year warranty.

 

Advantages

1. Power supply for PV array

① Ultra wide input voltage: 250-1500VDC, transient up to 1700VDC for 30s

② PV40-29BxxR3 can be powered directly through a high-voltage bus, with no additional PV panels, and no additional wires, which simplifies system design, increase effective power generation space, and reduce installation and maintenance costs.

 

2. Performance upgraded

 

3. High reliability

① High isolation voltage: Input-output voltage up to 4000VAC, leakage current < 3mA

② Multiple protections: Input under-voltage protection, input reverse polarity protection, output short circuit, over-current, over-voltage protection

③ Packages: Horizontal package, A5 chassis mounting, A6 DIN-Rail mounting

④ Certifications: Comply with UL1741, EN62109-1, CSA-C22.2 No.107.1 standards

 

 

Applications

PV40-29BxxR3 are widely used in renewable energy industries, such as photovoltaic, PV combiner box, solar tracking system, centralized inverter, PV array inverter, energy storage, solar pumping system and high-voltage DC conversion.

 

Solar tracking system

PV combiner box

As one of the most critical devices in a PV system, the higher the input voltage of the PV array in series, the fewer the number of combined boxes required in the system. Fewer combined boxes helps to reduce the risk of failure and improve safety and reliability.
