PM800 SERIES

Single and dual output

[ 2 YEAR WARRANTY ]

• Linear topology for low noise applications

• Tight line and load regulation

• Short circuit protection

• Pi input filter

• Six sided continuous shield

• No derating

The PM800 Series is a comprehensive line of four single output and five dual

output DC/DC converters with output power from 10 to 12 Watts. These high

performance modules offer excellent regulation with low ripple and noise, and

are especially useful in applications where higher output power levels are

needed in a compact module. A Pi input filter in all models minimizes reflected

ripple current while also providing for input spike attenuation. Six sided

continuous shielding, also standard, gives EMI/RFI suppression. All models

feature output current limiting, short circuit protection and input/output isolation

to 500VDC. Other specifications include: line regulation of ±0.02%; load

regulation of ±0.05% for single output models and ±0.02% for dual output

models; and an output voltage accuracy of ±3.0%.
