PM900 SERIES
Single and dual output
• 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.
SPECIFICATION All specifications are typical at nominal input, full load at 25°C unless otherwise stated
