The ECF40 series is designed to minimize the no load power consumption and maximize efficiency
to facilitate equipment design to meet the latest environmental legislation. Approved for medical and
ECF40:
ITE applications in either Class I or Class II installations, this range of single output AC-DC power supplies
3.00 x 1.50 x 1.10” (76.2 x 38.1 x 28.0 mm)
are packaged in a low profile 1.1” height with a foot print of just 1.5” by 3”. The ECF40 provides up to
40W convection-cooled over the full 90-264 VAC input range, and operates down to 80 VAC with minimal
de-rating. The power supply features two AC line fuses and low leakage currents required by medical applications. The low profile, low noise and safety
approvals covering ITE and medical standards allows the versatile ECF40 series to be used in a wide range of applications.
