Milton Keynes, UK, September 27, 2011: Cyntech Components, a specialist supplier of electro-mechanical components, announces a universal junction box for silicon-wafer solar PV modules that can be quickly customised to suit each application. It comes with three surface-mounted bypass diodes as standard but up to six can be installed.
There is a choice of soldered or crimped contacts, and the boxes can accommodate standard ribbon cables or non-ribbon crossing cables. This easy customisation means that only one type of box has to be stocked to meet the requirements of a variety of applications.
Sealed with a Gore-Tex® membrane, the IP67-rated box measures 111mm x 140mm x 26.5mm and accommodates between 2 and 8 ribbons with a maximum diameter of 7.5mm. The conductor cross-section can be 4mm or 6mm. Depending upon configuration, overall current rating is 20A and the junction box is rated at 1000 V DC to TÜV EN50521.
