Frequently Asked Questions

Can I use the DDR-15G-12 to power a 12V sensor or relay module from a 24V DC control bus?

Yes. The DDR-15G-12 accepts 9-36V DC input and outputs 12V at 1.25A (15W). A 24V control bus is in the middle of the input range, and 15W is sufficient for a few small sensors, a relay board, or a status display panel. The ultra-slim 17.5mm width conserves valuable DIN rail space.

Is the DDR-15G-12 suitable for powering a small embedded computer or IoT gateway from a 12V or 24V battery?

Yes, as long as the battery voltage stays within 9-36V. Many compact single-board computers and IoT gateways draw under 15W at 12V. The 4KVdc I/O isolation protects the embedded device from noise or transients on the battery bus, which is important in mobile or vehicle-mounted installations.

Can I use the DDR-15G-12 inside a compact DIN rail enclosure where space is limited?

Yes. At just 90.0 x 54.5 x 17.5 mm and 0.068 kg, it is one of the most compact DIN rail DC-DC converters available. The fanless design means no additional clearance is needed for airflow, making it ideal for small junction boxes and crowded control panels.

Does the DDR-15G-12 work in harsh-temperature industrial environments?

Yes. It is rated for -40°C to +85°C, which covers freezing warehouses, outdoor enclosures, and hot factory floors. Since it is fanless and has no moving parts, it is well suited for dusty or vibration-prone locations. Mount it inside a sealed enclosure for protection against moisture and debris.

What is the difference between the DDR-15G and DDR-15L series at 12V?

Both output 12V at 1.25A (15W) in an ultra-slim DIN rail package. The DDR-15G-12 accepts a 9-36V DC input (4:1 range), while the DDR-15L-12 accepts a different input voltage window. The G and L suffixes denote input voltage range variants, so choose the one that matches your DC bus voltage.
