(e.g., railways, industrial automation and automotive, remote radio control), thereby reducing inventory, time to market, and documentation.
Designed for harsh environments, the PQAE40-60-100U series meets the thermal shock and vibration requirements specified in EN61373 and MIL-STD-810F, and all comply with the Fire and Smoke standard EN45545-2. The PQAE40-60-100U series can operate from -40°C to +105°C case temperature, meeting very demanding and robust requirements, such as in construction vehicles, mining equipment, and heavy machinery process control.
Power designers for industrial and railway applications always face challenges in optimizing board power solutions when designing standardized equipment for worldwide operation with a wide variety of system bus voltages. In the railway industry, designers are constantly seeking the best power architecture to operate within the general input voltage range specified in EN50155, from 24V to 110V (including continuous operation under 14.4V dips and 154V transients).
To ensure power board designers have the highest level of flexibility, the PQAE40U (40W), PQAE60U (60W), and PQAE100U (100W) series have been developed to deliver stable full power across an extended input voltage range of 14V to 160V. For lower bus voltages, the 9V to 75V versions cover main battery voltages, maintaining peak voltage and continuous operation down to 75V.

The PQAE40-60-100U series, housed in a standard quarter-brick enclosure, is available in seven output voltages: 5, 12, 15, 24, 28, 48V, and 53V. They boast an efficiency of up to 90%, which, considering the extra-wide input range of up to 12:1, is an outstanding figure.
All models in the PQAE40-60-100U series feature comprehensive protection levels, including overvoltage, short-circuit, current limiting, and thermal shutdown. All units operate at a fixed switching frequency and include PI-type input filters. The operating temperature range is -40 to +105 degrees Celsius, and the storage temperature range is -55 to +125 degrees Celsius.
Designed for harsh environments, the PQAE40-60-100U series meets the thermal shock and vibration requirements specified in EN61373 and MIL-STD-810F. All products comply with IEC/UL/EN-60950, EN62368-1, and railway standards EN50155 and EN45545-2.
The PQAE40U (40W), PQAE60U (60W) , and PQAE100U (100W) are available in an industry-standard quarter-brick package (36.8 x 57.9 x 12.7 mm - 1.45 x 2.28 x 0.50 inches). The products are housed in a plastic enclosure with an aluminum base plate and filled with a UL94-V0 silicone compound. Four optional heat sinks with different height and airflow orientations are available upon request.
The 9 to 75VDC modules feature basic input/output isolation of 2,250VDC, and the 14 to 160VDC modules feature reinforced isolation of 3,000VAC.
The PQAE40U, PQAE60U, and PQAE100U models are RoHS compliant.
