The TEN
20WI is a new high efficiency isolated 20 Watt converter series
with industr y standard footprint. They feature a ver y 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.
