The EML15 is a series of open frame and encapsulated AC-DC single output power supplies
EML15:
designed for medical applications. The series provides a number of flexible mechanical options (-P): 2.44 x 1.21 x 0.95 (62.0 x 30.7 x 24.1 mm)
(-T): 3.10 x 1.25 x 0.91 (78.7 x 31.8 x 23.1 mm)
including PCB mount, open frame, chassis mount with screw terminals and a DIN Rail option. With
(-E): 2.56 x 1.31 x 0.96 (65.0 x 33.3 x 24.4 mm)
approvals to world-wide medical safety standards, compliance with class B for both conducted and
(-S): 3.30 x 1.36 x 1.04 (84.0 x 34.5 x 26.4 mm)
radiated emissions and a 130%, 30s peak load capability, these class II isolation parts benefit
system designers with easy integration into the latest healthcare products and applications.

Notes
1. Peak load lasting <30 s with a maximum duty cycle of 10%, average output power not to exceed nominal.
2. Add suffix to model number to define type: add -P for PCB mount, add -T for chassis mount, add -E for encapsulated, add -S for screw terminals.
3. A Screw terminal version (-S) is available with DIN clip attached, add suffix D, e.g. EML15US24-SD, DIN rail mounting kit is available as a seperate item,
order code ECL15 DIN CLIP.
