15 Watt

Single and Dual Output DIN Rail, Wide Input


DIN rail with internal input reverse polarity protection

With overload and short circuit protection, our 15 watt single and dual output DC-DC converter features internal input fuse and reverse polarity protection, a reliable snap-on for DIN Rail TS-35/7.5 or TS-35/15 and overload and short circuit protection. This design also has an internal input in-rush current limit circuit and an output DC-OK indicator.
