[ 2 YEAR WARRANTY ]
The A and F Series offer high input/output isolation of 500VDC with only 1mV
rms (40mV pk-pk) output ripple and noise. Other premium performance
features include line and load regulation of less than
±
0.1% and efficiencies of
up to 69%. The converters are encapsulated in a 2 x 2 inch industry standard
package with a 0.38 inch profile. The six sided copper case allows optimum
thermal conductivity and provides shielding for EMI/RFI suppression. A Pi input
filter reduces reflected ripple. Reliable operation is assured through the use of
efficient, design-derated components and by heatsinking all dissipating
elements directly to the metal case. This permits operation from -25
o
C to +71
o
C
with no derating or additional heatsinking required. A and F Series DC/DC
converter are suitable for a wide range of general industrial applications,
especially where low noise levels are required.

Measured from high line to low line.
Measured from full load to no load.
The A series case is connected to output common for all input voltages
except 48V when it is connected to + input.
Fixed frequency design provides for easier input filtering and better noise
performance.
The input voltage range can be increased to 10% under reduced loads.
