To help compensate for any voltage drop at the output, remote sense is also standard. If convection cooled, the power supply achieves 120 W output. Within the range, five models are available providing the popular 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 –A 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 has a 3 year warranty and is available now from stock and also through Farnell.
