High Isolation
Meets EN55022 and VDE0871 level B conducted noise
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.
SPECIFICATION
All specifications are typical at nominal input, full load at 25C unless otherwise stated

Measured from full load to no load.
4
The A series case is connected to output common for all input voltages
except 48V when it is connected to + input.
5
Fixed frequency design provides for easier input filtering and better noise
performance.
6
The input voltage range can be increased to 10% under reduced loads.
