SpecificationsJunction box for crystalline modules
A new junction box for crystalline modules expands the product portfolio of HUBER+SUHNER. The RADOX® SOLAR Box HS3 is 153 mm x 75 mm and therefore quite a bit smaller than its predecessors, the HA3 and RH3. It already conforms to the latest standards for the EN 50548:2011 and UL3730 and is available with various terminal designs. Therefore, it may be optimally used in different panel architectures and manufacturing processes.
Optimised for Automation
With 4mm2 RADOX® SOLAR cables and RADOX® SOLAR twist lock connectors, the box is delivered as always as a complete system with top RADOX® quality. Its design was optimised for current demands for fully automated production processes. It is ideally suited for use with automated systems due to defined robotic gripping surfaces and a stackable design. Because the surface has been changed, this box can also be used with vacuum exhausters. Furthermore, the potting process has also been optimised through an enlarged shaft, smaller potting volume (less than 8 ml), and a simplified potting procedure.
Good Electrical Data – Long Service Life
The HS3 is completely sealed and conforms to protection type IP67. It operates at temperatures between -40 and +85 degrees Celsius. The box possesses a low forward voltage drop due to the large conductor cross section, excellent contacting through welded wires, and, last but not least, due to the construction of connectors with a lamella spring contact.
As is the case for the entire product family, the box's design is based on patented thermal separation, whereby the box does not rest directly on the module, which allows air to circulate between the box and the module. Furthermore, a special method of heat dissipation prevents heat build-up on the module. An additional cooling plate in the box ensures that the heat from the diodes is distributed across a large surface, and that the diodes can operate significantly below the upper temperature limit in bypass mode. HUBER+SUHNER's design therefore ensures the best electrical data and maintenance-free use during the entire lifetime of the module.
