DC-DC power converters support critical voltage needs of automation devices

May 17, 2023
New converters from Antaira boost low power from panels up to 53VDC.

Industrial networking devices and software specialist Antaira Technologies (Brea, CA) has this month launched two DIN rail mounted DC-DC converters able to boost the 9-36VDC input power typical of control cabinets to a maximum adjustable output of 53VDC; and either up to 480 watts (DTD-480-0953-T) or 360 watts (DTD-360-0953-T).

As explained by Henry Martel, field application engineer with Antaira Technologies:

"In automation networks, 24 VDC in the panel is sufficient as input power for Ethernet switches and other devices with PoE that can internally boost low power up to the necessary 48 to 52 VDC. However, there are network devices requiring higher voltage that cannot increase low power on their own, such as larger non-PoE Ethernet switches with high port counts. Our new DTD product line acts as an external booster to those devices, giving engineers and administrators more options in the equipment they can install where space is a critical parameter."

Value proposition

Billed as exceptionally rugged and compact, the new DTD power converters from Antaira are shielded from industrial environments within an IP30 metal housing able to withstand a temperature range of -40°C to 75°C, along with exposure to shock and vibration.

With an eye toward minimizing downtime, the company says the new converters are safeguarded against poor power quality with protection against damaging short circuits, overload, reverse polarity, and under voltage. A built-in SVR feature allows adjustment of output voltage to address specific device needs.

Per a company statement, the Antaira DTD converters are not limited to one application but are designed to resolve power problems across a series of markets. As such, the DTD-480-0953-T and DTD-360-0953-T are optimized for diverse power needs, ranging from factory automation and video surveillance to solar and mobile networks.

While the converters are not a direct substitute for a solar panel power regulator, Martel noted that they can help boost the power from a 12- or 24-volt DC battery power storage to a more useful 48-52 VDC, compatible with other electronic devices such as laptops.

Also per the manufacturer, when installed on buses, the converters will not only boost power but also clean up the power that may be dirty from old alternators or other electronics on the same circuit, making them precise and stable for better performance.
