High-voltage DC-DC converter
27 February 2019, Power Electronics / Power Management
TDK announced the introduction of the TDK-Lambda brand PH300A280-5 DC-DC converter, completing the PH-A280 series of 200 V to 425 V input, 50 W to 300 W power modules. The new model is designed for data communications and renewable energy applications utilising 380 V high-voltage DC.
The new model is rated at 5 V/60 A and has a wide 2,5 to 6 V adjustment range to accommodate non-standard voltages. Packaged in the industry standard half-brick format (61,0 x 12,7 x 57,9 mm), it has an efficiency of 89% and can operate at full load with -40°C to +100°C baseplate temperatures. The converter can be conduction cooled, making it suitable for use in sealed outdoor enclosures, liquid cooled applications or convection cooled with an optional heatsink.
All PH-A280 modules have a standard feature set, including a five-year warranty, remote on-off, over-current and over-voltage protection. The series is fully isolated with an input to output isolation of 3000 V a.c. and safety certified to IEC/EN 60950-1, UL/CSA 60950-1 with CE marking for the Low Voltage and RoHS2 directives.
Additionally, the PH300A280 models are certified to EN 62477-1 (over voltage category III) for fixed installations with a permanent connection to a distribution panel. This avoids the need for a transformer to reduce input voltage transients.
