Relec announces two developments in the world of power management

14 January 2019

Take a closer look at the two new developments from Relec: PV Series Photovoltaic DC DC converter and the PMBus enabled power supplies.

PV Series Photovoltaic DC DC converter – World Electronics Achievement Award

Relec is delighted to announce that Mornsun’s PV series of ultra-wide input DC DC converters has won the prestigious Aspencore World Electronics Achievement Award 2018 for best power management/voltage converter of the year.

The PV series has been developed for the photovoltaic industry as a stand-alone DC DC converter to power control systems in remote locations. The PV series products have input ranges of either 100 to 1,000V or 200 to 1,500V and are available with output powers up to 200 Watts.

The wide input operating voltage of the PV series makes them suitable for use as controllers in combiner boxes (linking multiple panels in series to reduce cable diameters and costs), actuator position control and telemetry systems.

Applications for the PV series are not just limited to the solar sector. With the simple addition of a bridge rectifier and a small smoothing cap, you have a converter which can operate from single phase and 2 phase systems. If you need application help, please get in touch with Relec who will be happy to help.

PMBus enabled power supplies from Excelsys – CoolX and Xsolo

Do you need more from your power supply than just volts and amps? The CoolX and Xsolo families from Excelsys are now available with full implementation of PMBus (power management bus) protocol. PMBus provides the developer full control of their system with on the fly adjustment of output voltage and current limit. This gives the engineer the ability to optimise the power supply to the features of individual loads.

PMBus can also be used in working systems where control of output voltage and current are inherent in the feedback loop for correct operation as well as providing status and temperature information on individual modules.

If you have an application that would benefit from digital control, please give Relec a call. Relec can even supply you with a PMBus GUI, an invaluable development tool, to help you get up and running with the minimum of fuss.
