Description

The DDR-30G is a 30W DIN Rail type DC-DC converter with a 35mm (2SU) profile, designed for industrial control cabinets and distributed power systems. A 4:1 wide input voltage range of 9~36Vdc supports a broad range of DC supply sources, while reinforced 4KVdc I/O isolation ensures noise-free power conversion. Cooled entirely by free air convection with no minimum load requirement, it operates reliably from -40~+85°C.

Frequently Asked Questions

Can I use the DDR-30G-12 to power a 12V sensor network from a 24V battery in an industrial panel?

Yes. The DDR-30G-12 accepts 9-36V DC input and outputs 12V at up to 2.5A (30W), so a 24V battery bank or DC bus is well within its input range. At 30W it can supply several 12V sensors, relays, or indicator lights mounted alongside it on a DIN rail.

Is the DDR-30G-12 suitable for powering a 12V embedded controller in a small automation enclosure?

Yes. With 30W at 12V/2.5A, the DDR-30G-12 can power compact embedded controllers, single-board computers, or data acquisition modules. Its ultra-slim 90.0 x 54.5 x 35.0 mm DIN rail form factor and 0.12 kg weight make it a good fit for space-constrained control cabinets.

Can the DDR-30G-12 convert a 12V or 24V solar panel output to a regulated 12V for monitoring equipment?

Yes, provided the solar source stays within 9-36V DC. Even if the panel voltage fluctuates with sunlight intensity, the DDR-30G-12 maintains a stable 12V output for data loggers, communication radios, or camera systems drawing up to 2.5A total.

Will the DDR-30G-12 operate in a freezing outdoor equipment cabinet?

Yes. The DDR-30G-12 is rated for -40°C to +85°C and uses passive convection cooling with no fan. It will start and run reliably in unheated outdoor enclosures, cold storage environments, or mountaintop installations as long as the enclosure prevents direct water contact.

How does the DDR-30G series compare across its available output voltages?

The DDR-30G series shares the same 9-36V DC input range and compact DIN rail housing. Output options include the DDR-30G-5 (5V/6A, 30W), DDR-30G-12 (12V/2.5A, 30W), DDR-30G-15 (15V/2A, 30W), and DDR-30G-24 (24V/1.25A, 30W). All are 30W rated, fanless, and have 4KVdc I/O isolation — choose based on the voltage your load requires.
