Additional output voltages extend power module series

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

The six models are rated at 3.3V 15A or 20A, 15V 5A or 10A and 28V 2.7A or 5.4A. The outputs of the new models can be adjusted by -20% to +10% to accommodate non-standard voltages.

Featuring an industry standard quarter-brick package, the units are said to give efficiency of up to 90%, and can operate across a -40 to 100°C temperature range. The converters can also be conduction cooled making them suitable for use in sealed outdoor enclosures or liquid cooled applications.

Standard features include remote on-off, over-current, and over-voltage protection. The series is fully isolated with an input to output isolation of 3000Vac and are safety certified to IEC/EN 60950-1, UL/CSA 60950-1 with CE marking for the Low Voltage and RoHS2 Directives.
