These popular chassis-mountable linear power modules feature 13 single, 17
dual and 10 triple output models. This series is designed for special applications
where mounting on a housing or metal chassis is required. Input/output
connections are made to screw terminals on a barrier terminal strip and
mounting is made convenient by means of four threaded inserts in the bottom
of each module. For maximum safety, all power transformers are split bobbin
wound, rather than layer wound, to give total isolation between primary and
secondary. Overvoltage crowbar protection is standard on all 5V outputs for
protection of logic circuitry. Standard input voltage is 115VAC at 47 to 400Hz;
other optional inputs are 220, and 240VAC. Input/output isolation voltage is
2500VAC. Output current limiting and short circuit protection are standard.
