High power terminal blocks focus on photovoltaic requirements

Aimed at OEMs, CEMs, electronic manufacturers, PCB manufacturers and assemblers, the photovoltaic industry, and those in building and automation, the terminals, which are available from Switchtec are suitable for use in photovoltaic products, high voltage and high current applications, and any application that needs or uses large cable.

With the general move towards fully integrated PCB assemblies, manufacturers are demanding larger PCB terminal blocks for applications such as Photovoltaic, which due to their nature requires terminal blocks capable of handling high voltages and high currents. Euroclamp designed the MVP35 terminal block to fulfil this requirement. The MVP35 is designed to accept 35 mm2 (2AWG) stranded or rigid (solid) cable, or 2 x 10 mm2 (2x8AWG) cables.

The MVP35 has two basic designs, the standard MVP35 PCB version (flangeless model) or the MVP35K model that has two flanges for surface mounting to the PCB with screws. Due to the large cable sizes being used, movement of or pressure from the cable could potentially weaken or damage the PCB connection. To allay this effect, the MVP35 has a four pin PCB footprint to give maximum strength to the terminal/PCB junction. The MVP35K with its additional flanges adds even more mechanical strength to the assembly.

Euroclamp has chosen to produce the MVP35 with a 15 mm pitch size for two important reasons. Firstly, this larger size gives good PCB retention strength and secondly, the MVP35 (not the MVP35K) features a dovetailed design, allowing the terminals to be linked together, modular style. The MVP35 is a single pole PCB terminal but with its modular design it can create multiple pole terminal blocks e.g. 2, 3, 4, or 6 pole thus adding greater flexibility. Due to the terminals’ high power ratings, 15mm pitch is needed to give adequate clearance for cable entry.

The MVP35 is available as standard in green, but as with all of Euroclamp’s terminal blocks they are also available in red, yellow, blue, orange and black. Special colours are also available upon request.

The MVP35 series are CE marked, cUL approved and have IP20 touch proof terminals. An operating temperature range of -30 to +130 degrees C is tolerated, again making them suitable for many applications as well as photovoltaic. The terminals are manufactured from PA -UL94V0 plastic.

Euroclamp has used its vast experience in manufacturing PCB terminal blocks to produce the MVP35 high voltage terminal block.  Developing and adapting existing technologies and processes, Euroclamp has been able to add the MVP35 terminal to its range.

The MVP35 PCB terminal block is an important addition to the Euroclamp range. All terminals in the range are available ex stock from Switchtec who are also able to provide technical support in choosing the correct terminal for the application, as well as after sales support.
