Half brick DC-DC converter for data communications and renewable energy applications

TDK Corporation has introduced the TDK-Lambda brand PH600A280‑24 DC-DC converter. This extends the PH-A280 series of 200VDC to 425VDC input power modules from 50W to 600W. The new 24V output model is intended for data communications, power transmission and renewable energy applications using a 380V HVDC input.

The new model is rated at 24V 25A and has a wide 14.4V to 28.8V adjustment range to accommodate non-standard voltages. Packaged in the industry-standard half-brick package (61mm x 12.7mm x 57.9mm), it has an efficiency of 93% and can operate at full load with -40C to +85C baseplate temperatures, derating linearly to 80% load at +100C. The converters can be conduction-cooled, making them ideal for use in sealed outdoor enclosures or liquid-cooled applications.

All modules offer a five-year warranty, remote on-off and over-current and over-voltage protection. The series is fully isolated with an input to output isolation of 3,000VAC and is safety certified to IEC/EN/UL/CSA 62368-1 with CE marking for the Low Voltage and RoHS Directives. Additionally, the model is certified to EN 62477-1 (Over Voltage Category III) for fixed installations with a permanent connection to a distribution panel.
