PM800 SERIES
Single and dual output
• Line ar topology for low nois e applications
• Tight line and load re gulation
• Short circuit prote ction
• Pi input filte r
• Six s ide d continuous s hie ld
• No de rating
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% .
