DC/DC converters for industrial and solar array applications

Relec now has 1,000V and 1,500V DC/DC converters for industrial and solar array applications.

Using solar panels, or arrays, to absorb sunlight to convert it into electricity brings many challenges in order to create an economically viable and sustainable source of power.

Not least of the challenges is a sufficiently robust and flexible DC/DC converter to deal with the full output voltage from the photovoltaic array (PV).

Relec Electronics is pleased to announce the availability of two ranges of very wide input dc dc converters. With input ranges covering 100–1,000V dc (PVxx-27BxxR2) and 200–1,500V dc (PVxx-29xx) the PV series have primarily been designed as a building block for use in photovoltaic array combination units.

Significant savings can be made by series connection of arrays (lower copper losses). A DC/DC converter that can cope with the full output voltage from these arrays can be used to form the basis of the control system.

The PV series is available in various output voltages and power ranges from 5W to 40W with modules having the following features:

Ultra-wide input voltage range: 100-1,000V or 200-1,500VDC
5V, 12V, 15V or 24V outputs available (5–40W)
Industrial grade operating temperature: -40 to+70
4,000VAC I/O isolation voltage
Input under-voltage, reverse polarity, output short-circuit, over-current and over-voltage protection
UL1741/CSA C22.2 No.107.1/EN62109 approval
PCB & Din Rail mounting options
High efficiency, low ripple & noise

The PV series are not just suitable for solar arrays. The wide input range and isolation levels make them suitable for use a wide variety of industrial applications as front end power supply components covering both single and three-phase voltages.

At Relec Electronics the philosophy is to help design engineers build better solutions.

At Relec Electronics the philosophy is to help design engineers build better solutions.

We are proud to have one of the most comprehensive power supply ranges available, for both DC to DC and AC to DC applications. In addition, we offer a range of complementing products including EMC filters, switches and displays. Our aim is to build partnerships with customers and suppliers to both understand their requirements and to ensure a reliable supply of robust, yet technically advanced components that can be relied upon in the long term.

Power supplies, circuit protection and interface products form the backbone of our business. We work very hard to bring high-quality competitive products to the market, and our customers can be assured that any product we are promoting will not have reached them without full dialogue with the supplier together with a personal factory audit.

We believe the future is to offer our clients more choice thereby ‘adding value’ to their projects. This is achieved by offering custom products in all the lines we supply and by offering manufacturing services such as sub-assemblies and finished products. In our UK warehouse, we hold significant stocks of both standard and customer-specific parts and offer all the commercial services you would expect, including JIT, KANBAN, and specialist agreements tailored to suit individual customer needs.

Relec’s sales and technical support personnel, including our QA department, are all qualified engineers and are committed to ensuring that all aspects of our service meet and exceed today’s high expectations. We pride ourselves on providing extensive technical support for design engineers and full commercial support for our customers. By working with a limited number of manufacturers, who are leaders in their various technologies, Relec can provide the best solutions available.
