In the TCL range of DIN-rail power supplies are 4 models for DC input voltage available. The wide input ranges of 9.5–18 VDC resp. 18–75 VDC means these models
can be operated from all popular DC supply voltage systems.
With tightly regulated output voltage these DC/DC converters provide a reliable
power source for sensitive loads in industrial process controls, factory automation
and other equipment exposed to a critical industrial environment. A further application for these converters is to isolate a specific load from the 24 V bus voltage.
A further application for these converters is to isolate a specific load from the 24V
bus voltage. Easy installation is provided with snap-on mounting on DIN-rails and
detachable screw terminal block.
