TDK Corporation announces an extension to the PH-A280 series of high voltage input DC-DC converters. Capable of operating from 200 to 425Vdc, the new 3.3V, 15V and 28V output power modules are suitable for use in data centres, tele-communications and renewable energy applications utilising a 380V nominal high voltage DC bus.

LA005383 - PH-A

The six new models are rated at 3.3V 15A or 20A, 15V 5A or 10A and 28V 2.7A or 5.4A. This extends the existing 50 to 150W PH-A280 product range of 5V, 12V, 24V and 48V outputs. The outputs of the new models can be adjusted by -20% to +10% (-10% to +20% for the 3.3V output) to accommodate non-standard voltages.

Following the industry standard quarter-brick package (37.2 x 12.7 x 58.3mm), the high efficiency units, up to 90%, can provide full load with -40°C to +100°C baseplate temperatures. The converters can also be conduction cooled making it suitable for use in sealed outdoor enclosures or liquid cooled applications.

Standard features include remote on-off, over-current, and over-voltage protection. All PH-A280 models carry a five-year warranty. The series is fully isolated with an input to output isolation of 3,000Vac and are safety certified to IEC/EN 60950-1, UL/CSA 60950-1 with CE marking for the Low Voltage and RoHS2 Directives.
