XP Power Provides Open Frame Single-Output AC/DC Power Supplies

XP Power has provided its ECM140 series of open frame single-output AC/DC power supplies. Measuring 3 x 5 x 1.3 inches (76.2 x 127 x 33 mm) and offering a high power density of 7.9 Watts per cubic inch, the ECM140 requires just 10 CFM of forced air-cooling to achieve the full 148 W output. The supply includes a 12 V / 0.5 A fan output as standard, removing the need for an additional voltage source to power a fan. If convection cooled, the power supply achieves 120 W output. Within the range, five models are available providing the outputs of 12, 15, 18, 24 or 48 VDC. The series meets the electrical safety standards of both IEC 60601-1 / EN 60601-1 for medical equipment and IEC 60950-1/EN 60950-1 for industrial and IT equipment. The series also meets EN 55022 specifications for Class B conducted emissions without the need of additional filtering components. Using a highly efficient resonant topology, the units typically achieve 88% efficiency above 70 W with a very flat efficiency curve. This approach also aids to improve the units EMI performance. In addition to the standard version, all models are also available with an options package. The –an option includes a 5 V standby supply output, power OK and dual polarity inhibit signals. By providing these features as options, the base price of the power supply series is kept competitive. The ECM140 is priced at $77.22 each for OEM quantities, has a 3 year warranty and is available now from stock.
