PM500 and VM500 SERIES

Single, dual and triple output

[ 2 YEAR WARRANTY ]

• OVP on 5V outputs

• Split bobbin wound

• PCB mounting

• UL and CSA approved

• 115, 220 and 240VAC input

• Short circuit protection

• The VM500 Series has EN60950 approval

These encapsulated, PC-mountable linear power modules feature 23 single

output, 14 dual output and 13 triple output models for a wide variety of printed

circuit board applications. The 5V output of all models have overvoltage

crowbar protection as a standard feature. For maximum safety, all power

transformers are split bobbin wound, rather than layer wound, to give total

isolation with low coupling capacitance between primary and secondary.

Conservative design and rating of these modules results in reliable operation

and long life. Standard input voltage is 115VAC; other optional inputs are 220

and 240VAC. Most models are available in standard and alternate pin

configurations for second sourcing applications. This series includes 5 sub-

miniature modules for lower power applications where minimum circuit board

space is available.
