PM900 SERIES

Single and dual output

[ 2 YEAR WARRANTY ]

• Extremely tight line and load regulation

• Short circuit protection

• Pi input filter

• Low ripple output current

• Conducted noise EN55022, EN55011 level B

• Linear topology for high output accuracy and regulation

The PM900 Series of 5 and 6 Watt DC/DC converters are a broad line of high

performance modules with many important features and specifications as

standard. All models contain Pi-type input filters to minimise reflected ripple

current. They are packaged in low profile 2.0 x 2.0 x 0.4 inch cases with

standard and two alternate pin-outs designed for direct PC card mounting. The

units also feature output current limiting, short-circuit protection and

input/output isolation of 500VDC. Other specifications include: an efficiency of

65%; line regulation of ±0.02%; load regulation of ±0.04% for single output

models and ±0.05% for dual output models; low ripple and noise (10mV pk-pk

for single output models and 6mV pk-pk for dual output models); and an output

voltage accuracy of ±1.0%. PM900 Series DC/DC converters are intended for a

wide variety of general industrial applications, especially where low noise

performance is required.
