EML30 Series AC-DC Power Supplies
The EML30 is a series of open frame and encapsulated AC-DC single output power supplies
designed for medical applications. The series provides a number of flexible mechanical options
including PCB mount, open frame, chassis mount with screw terminals and a DIN Rail option. With
approvals to world-wide medical safety standards, compliance with class B for both conducted and
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.

Models & Ratings
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. EML30US24-SD, DIN rail mounting kit is available as a seperate item,
order code ECL25/30 DIN CLIP.
