PM300 SERIES

Single, dual and triple output

[ 2 YEAR WARRANTY ]

• Terminal strip connections

• Chassis mounted

• Split bobbin wound

• UL and CSA approved

• 115, 220 or 240VAC input

• Short circuit protection

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.
