Phoenix Contact Offers New High-Voltage DC/DC Converter

December 28, 2020 by Alessandro Mascellino

Electrical engineering firm Phoenix Contact has released the TRIO 1500 V DC/DC converters for high-voltage applications.

The components are designed with a circuit to ensure resistance against electromagnetic interference.


Phoenix Contact: A Company Overview

Based in Blomberg, Germany, Phoenix Contact is a global manufacturer of industrial automation, interconnection, and interface solutions. The company develops various electronic components, including controllers and PLCs, I/O systems, and power supplies.

Phoenix Contact’s products follow U.S. and international safety standards: DIN EN ISO 9001, 14001, 50001, 29990, OHSAS 18001, IRIS.

The company was founded in 1923 by Hugo Knümann and has grown steadily through the century. In 2019, the company had a reported turnover of €2.48 billion (approximately $3 billion).

Today, Phoenix Contact owns active manufacturing facilities in twelve countries, including China, India, Russia, and the USA. According to its website, the company is currently employing a worldwide total of 17,600 people.


TRIO 1500 V DC/DC Converters

Phoenix Contact designed the new DC/DC converters to support a wide input range of 510 V DC to 1650 V DC, then convert that voltage to a regulated 24 V DC.

The components feature internal overvoltage protection circuitry, a low output voltage ripple, and a high mean time between failures (MTBF) to optimize their performance.

The TRIO 1500 V DC/DC converters have high surge voltage resistance and safe grounding circuitry for different grounding applications. Users can install the devices within pre-existing configurations. 

They offer push-in connection capabilities, and the ability to be installed in parallel. The new DC/DC converters offer a relay output feature for remote monitoring of the output voltage.


Designed for High-Voltage Applications

The TRIO 1500 V DC/DC converters are suited for railway and solar applications.

The devices can be utilized to convert the high D.C. voltage coming off the third rail of a three-rail system to a steady 24 V DC, then use it to power monitoring and analytical field devices. These new DC-DC converters can also be utilized in solar applications to power heating equipment, fans, D.C. circuit breakers, and lighting.

The components are certified according to the UL 62109-1 UL Standard, which describes the safety requirements of power converters for use in photovoltaic power systems.

The autonomous nature of the new converters offers flexible power options and easy installation within the arrays, circumventing issues related to supplying distributed A.C. power to P.V. data acquisition hardware via trenching and conduit runs. If used with wireless communications, these DC-DC converters allow for the installation of entirely autonomous data systems.
