Certified toEN 62477-1 (Over Voltage Category III) for fixed installations with a permanent connection to a distribution panel, the PH600A280‑24 DC/DC converter has been added to the PH-A280 series by TDK-Lambda.

The 600W DC-DC converter joins the 200 to 425V DC input power modules in the series, which now range from 50 to 600W. This latest model is designed for data communications, power transmission and renewable energy applications using a 380V high voltage direct current (HVDC) input.


It is rated at 24V 25A and has an adjustment range of 14.4 to 28.8V to accommodate non-standard voltages.

It is packaged in the industry standard half-brick package (61.0 x 12.7 x 57.9mm), and has an efficiency of 93%. It is able to operate at full load (-40 to +85°C baseplate temperatures) derating linearly to 80% load at +100°C. for outdoor applications, the converter can be conduction cooled for use in sealed enclosures or applications that use liquid cooling.


All PH-A280 modules have remote on-off and over-current and over-voltage protection. The series is fully isolated with an input to output isolation of 3,000V AC and all models are certified to IEC/EN/UL/CSA 62368-1 with CE marking for the Low Voltage and RoHS Directives. Each model in the series also carry a five-year warranty.
