TDK Corporation announces the introduction of the TDK-Lambda PH-A280 series
of DC-DC power modules with high voltage DC input. These quarter-brick modules
operate from a wide range DC input of 200 to 425VDC, which is widely used in
HVDC (High Voltage DC Current) and solar cell related applications.

The PH-A280 power modules are available in four output power levels of 50W,
75W, 100W and 150W. Nominal output voltages consist of 5V, 12V, 24V 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 series.

The modules can operate at full load over a wide 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 TDK-Lambda’s 5-year
warranty. All models have an input-to-output isolation of 3kVAC, are
safety-approved to UL/CSA/EN60950-1 and carry the CE mark in accordance with the
LV Directive.
