TDK Corporation announces the introduction of an extension to the TDK-Lambda PH-A280 series of DC-DC power modules with high voltage DC input. Operating from a wide range DC input of 200 to 425VDC, which is widely used in HVDC (High Voltage DC Current) applications, the PH-A280 range now includes 3.3V, 15V and 28V outputs.
The six new PH-A280 power modules are available in three output power levels – 75W, 100W and 150W. The complete product family encompasses nominal output voltages of 3.3V, 5V, 12V, 15V, 24V, 28V or 48Vdc; adjustable by -20% to +10% (+/-20% for 5V output models). Efficiencies of up to 90% are achieved, an improvement of 5% over the prior PH series.
All modules operate at full load over a baseplate temperature range of -40 to +100°C making them suitable for liquid, air cooled or conduction cooled systems. The dimensions follow the industry standard quarter brick format (37.2 x 12.7 x 58.3mm).
As standard, the PH-A280 units are equipped with remote sense, remote on/off, overvoltage and overcurrent protection circuitry and include a 5-year warranty. All models have an input-to-output isolation of 3kVAC, are safety-approved to UL/CSA/EN 60950-1 and carry the CE mark in accordance with the LV Directive.
