The DTJ15 and DTJ20 series of DC-DC converters from XP Power can be DIN rail or chassis mounted to provide 15W and 20W in rugged industrial designs.

XP Power has launched two series of wide input DIN rail power supplies providing 15W and 20W for indistrial and IT systems. The flexible specification allows devices with incompatible voltages to be easily integrated into such designa.

The DTJ15 and DTJ20 series can be installed to a chassis or DIN rail and connected via screw terminals and require no additional components for protection or EMC compliance.

The series offers 15W or 20W of power and suit a wide variety of applications including process monitoring and control, industrial robotics, elevators and moving walkways, safety monitoring, gaming systems, door control, communications and telemetry to name just a few.

A key feature of the DIN rail DC-DC converters is the 4:1 input range covering 9VDC to 36VDC and 18VDC to 75VDC. This supports a variety of input sources including multiple nominal battery voltages and vehicle supplies.

Both series have 14 variants with single-output (3.3V, 5.0V, 12.0V & 15.0V) and dual output (±5.0V, ±12.0V & ±15.0V) options in both input ranges. The single output types allow the output voltage to be trimmed by ±10% to accommodate voltage drops in cabling when the load is located remotely. A remote on / off enables the DIN rail DC-DC converters to be controlled by software allowing remotely located installations to be operated efficiently.

Reverse polarity protection provides peace of mind in case the devices are inadvertently wired incorrectly during installation while built-in input and output protection ensures that the load and the DC-DC converter are always protected during any fault condition.

The DIN rail DC-DC converters can operate up to 100ºC, allowing use in harsh environments as well as within sealed environments (such as IP67 enclosures) where there is no forced airflow. The ability to operate at altitudes up to 5000m ensures that the DTJ15 and DTJ20 can be deployed worldwide.
