WARNINGS!
- These units are not battery chargers! Hence, do not connect these units directly to a battery for
battery charging purposes.
- These units are designed to be used on Negative Grounded Systems only. Do not connect the input
/ output sides to a Positive Grounded System.
- The input and output sides have a common Negative Ground. Hence, there is no isolation between
the input and the output sides.

2. DESCRIPTION
SDC-15 and SDC-23 are non-isolated DC to DC converters that convert 24 VDC nominal voltage (range 20 VDC to
35 VDC) to 12 VDC nominal voltage (13.8 VDC). The input and output sides have a common Negative Ground.
Hence, there is no isolation between the input and the output sides. Both the input and output sides are
isolated from the chassis of the unit.
3. PROTECTIONS
3.1 Overload / Short Circuit
The units are protected against overload by current limiting. When the output current reaches the current
limit value (please see the specs), the output voltage will drop and will no longer be regulated. The unit will
reset automatically once the overload condition is removed.
