PM700 SERIES

Single and dual output

[ 2 YEAR WARRANTY ]

• 62% typical efficiency

• Low output ripple and noise

• Pi input filter

• No derating

• Short circuit protection

• Meets VDE 0871 level B

This series of general purpose DC/DC converters from Computer Products

includes three single output and four dual output models. The PM700 series

provides excellent voltage regulation and isolation with low ripple and noise at

three Watts output power. These compact modules contain pi input filters to

minimise reflected ripple current. Other important specifications include: a

minimum efficiency of 61%; line regulation of ±0.02%; load regulation of

±0.04%; low ripple and noise 10mV pk-pk; 500VDC isolation; and an output

voltage accuracy of ±1.0%.
