Descripꢀon:
The PM450 series comprising single and mulꢀple output models for 450-480 waꢁs of conꢀnuous output power is specially
designed for medical and ITE applicaꢀons. They operate at 90-264VAC input voltage without the need of a selector strap.
The units are constructed on a printed circuit board with a U-bracket for mechanical support and heat sinking. A cover-and-
fan assembly can be added during manufacturing.

1. Suffix “B” in model numbers denotes U-bracket form. Change “B” to “C” for enclosed form with cover and fan assembly, e.g. PM450-14C.
2. All outputs are floaꢀng. They can be connected externally for posiꢀve or negaꢀve output.
3. Output #1 can be adjusted within ±5% of its nominal voltage.
4. Output #3 can be adjusted within ±15% of its nominal voltage.
5. 450-480 waꢁs for “C” version with cover and fan assembly. 225-240 waꢁs for “B” version without moving air (maximum current of output #1 & 2
derated to 50%), or 450 waꢁs with 40 CFM forced air provided by user.
6. All models may be operated at no-load. At no-load, output voltage tolerance increases to ±10%.
