Frequently Asked Questions

Can I use the DDR-15G-24 to generate a 24V control signal rail from a 12V battery system?

Yes. The DDR-15G-24 accepts 9-36V DC and boosts or regulates to 24V at 0.63A (15W). This is useful when you need a 24V rail for small PLC inputs, indicator lights, or relay coils in a system powered by a 12V battery bank. The 4KVdc I/O isolation prevents ground loop issues between the battery and the 24V circuit.

Is the DDR-15G-24 suitable for powering a small 24V industrial sensor loop from a 24V or 28V DC bus?

Yes. Even though the input and output are both near 24V, the converter accepts 9-36V input and provides a clean regulated 24V output at up to 0.63A. This is useful for isolating a sensitive 4-20mA sensor loop from a noisy DC bus, thanks to the 4KVdc I/O isolation barrier.

Can I use the DDR-15G-24 in a compact junction box for building automation?

Yes. At only 90.0 x 54.5 x 17.5 mm, it fits into small DIN rail junction boxes commonly used in building automation for HVAC damper controls, lighting relays, or occupancy sensor loops. The 15W capacity covers a small cluster of low-power 24V devices.

Can the DDR-15G-24 handle temperature extremes in an uninsulated rooftop equipment enclosure?

Yes. The -40°C to +85°C operating temperature range accommodates both winter freezing and direct summer sun heating inside a rooftop enclosure. The fanless design eliminates maintenance concerns from filter clogging or fan bearing failure. Use a sealed NEMA-rated enclosure to protect against rain and dust.

What output voltages are available in the DDR-15G series besides 24V?

The DDR-15G series offers five output voltages, all with the same 9-36V DC input range: 3.3V/3.5A (11.6W), 5V/3A (15W), 12V/1.25A (15W), 15V/1A (15W), and 24V/0.63A (15W). They share the same ultra-slim 17.5mm DIN rail package, fanless design, and 4KVdc I/O isolation.
