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%.
SPECIFICATION All specifications are typical at nominal input, full load at 25°C unless otherwise stated
