The TEN 20WI is a new high efficiency isolated 20 Watt converter series
with industry standard footprint. They feature a very wide input voltage
ranges of 9 36 VDC and 18 75 VDC. Overload and overvoltage
protection as well as remote of/off are included as standard. Built-in filters
for both input and output minimizes the need of external filtering.
The TEN 20WI series is targeted specially at mobile systems, telecommuni-
cation, industrial and distributed power applications where a 4:1 input
voltage range is required.
