In addition, they offer multiple protections, multiple encapsulations, and a 3-year warranty.
Advantages
1. Power supply for photovoltaic panels
① Ultra-wide input voltage: 250-1500VDC, transient up to 1700VDC for 30s.
② The PV40-29BxxR3 can be powered directly through a high-voltage bus, without additional PV panels or cables, simplifying system design, increasing effective power generation space, and reducing installation and maintenance costs.
2. Improved Performance
3. High Reliability
① High Isolation Voltage: Input-output voltage up to 4000VAC, leakage current < 3mA.
② Multiple Protections: Input undervoltage protection, input reverse polarity protection, output short circuit protection, overcurrent protection, overvoltage protection.
③ Formats: Horizontal package, A5 chassis mount, A6 DIN rail mount.
④ Certifications: Complies with UL1741, EN62109-1, and CSA-C22.2 No.107.1 standards.
Applications
The PV40-29BxxR3 are widely used in renewable energy industries, such as photovoltaics, photovoltaic combiner boxes, solar tracking systems, centralized inverters, photovoltaic array inverters, energy storage, solar pumping systems, 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 series PV array, the fewer combiner boxes are required. Fewer combiner boxes help reduce the risk of failures and improve safety and reliability.
