Ideal industries and applications

The 1500 V TRIO DC/DC converter can be used in essentially any application that requires the conversion of a high DC voltage to a stable 24 V DC. Two significant industries that will benefit from this DC/DC converter are the rail and solar industries.

Rail applications

Railway applications that provide electric to railway trains using a third rail, often referred to as the conductor rail, can utilize this converter to convert the high DC voltage coming off the rail to a steady 24 V DC. This 24 V DC can supply power to monitoring and analytical field devices that require a 24 V DC input.

Solar applications

The ideal application for the new 1500 V TRIO DC/DC converter resides in the solar industry. These days, photovoltaic (PV) systems are operated at voltage levels up to 1500 V DC. This presents new challenges for technology in general, and for DC/DC converters specifically. The TRIO DC/DC converter was specially developed for this type of application – and it now satisfies the EN 62109 safety standard for use in voltage ranges up to 1500 V DC.

Trenching and conduit runs have been the most frequently used methods of supplying distributed AC power to PV data acquisition hardware. However, this method has high upfront installation costs and limited flexibility in making changes to the power wiring installation. The array-powered DC/DC converter’s autonomous nature offers flexible power options and easy installation within the arrays. When used with wireless communications, completely autonomous data systems are possible. In powering distributed PV data acquisition systems, array-powered DC/DC converters can assist in supporting the efficient asset management of solar arrays.

Array-powered DC/DC converters offer the advantages of hard-wired power distribution systems, as well as the flexibility of an autonomous power system. By utilizing the distributed nature of DC interconnections within an array, cabling to power PV data acquisition hardware is minimized. In addition, 1000 V and 1500 V nominal input array voltage models allow installation with both C&I and utility scale installations. Low voltage 24 V DC output is compatible with most data acquisition hardware such as weather data, solar irradiance, back-of-module temperatures, and combiner box monitoring. The 24 V DC output can also power heating equipment, fans, DC circuit breakers, and lighting.
