30 Watt

Single and Dual Output DIN Rail, Wide Input


Internal input fuse protection

With a reliable snap-on for DIN rail and over voltage protection, our 30 watt single and dual output DC-DC converter features internal input fuse protection, an output DC-OK indicator, case protection that meets IP 20 and internal input reverse polarity protection. The 30 watt model also has an I/O isolation of 1600 Vdc.
