Mean Well DDR-30L-15 DC-DC Converter - 30W - 18~75V in 15V out
The DDR-30L is a 30W DIN Rail type DC-DC converter with a 35mm (2SU) profile, suited for systems powered from 24V or 48V DC buses. A 4:1 wide input voltage range of 18~75Vdc covers nominal 24V and 48V supplies, and reinforced 4KVdc I/O isolation ensures clean, noise-resistant power conversion. Cooled by free air convection with no minimum load requirement, it operates across a -40~+85°C working range.

Frequently Asked Questions
Can I use the DDR-30L-15 to power 15V analog instrumentation from a 48V DC battery bank?
Yes. The DDR-30L-15 accepts 18-75V DC input, so a 48V battery bank (typical range 40-58V) falls well within its operating window. It provides a stable 15V output at up to 2A (30W) with 4KVdc isolation, which helps protect sensitive analog measurement circuits from noise on the battery bus.
Is the DDR-30L-15 a good fit for powering legacy 15V industrial control boards in a DIN rail panel?
Yes. Many older PLC I/O modules and industrial control boards require 15V DC. The DDR-30L-15 delivers 15V at 2A on a standard DIN rail mount with an ultra slim 35mm profile, making it a drop-in solution for retrofitting panels that have a 48V or 72V DC distribution bus.
Can the DDR-30L-15 convert a 24V solar system bus to 15V for charging or powering peripheral devices?
The DDR-30L-15 requires a minimum input of 18V DC. A nominal 24V solar bus can dip below 18V under heavy load or low-charge conditions, so you should verify that your bus voltage stays above 18V during operation. When the input stays in range, it will deliver a stable 15V at up to 2A with full isolation.
Can I install the DDR-30L-15 in an environment with high ambient temperatures?
The DDR-30L-15 operates from -40°C to +85°C, making it suitable for hot industrial environments such as factory floors, engine rooms, or enclosed electrical cabinets without active cooling. Its fanless design relies on convection, so adequate airflow around the unit helps maintain long-term reliability at the upper end of that range.
How does the DDR-30L-15 compare to other 15V options in the DDR series?
The DDR series offers 15V output in several wattage tiers: the DDR-15L-15 provides 15W at 1A, the DDR-30L-15 provides 30W at 2A, and the DDR-60L-15 provides 60W at 4A. All three share the same 18-75V DC input range and DIN rail form factor. If you need a lower input voltage range instead, the G-suffix models (DDR-15G-15, DDR-30G-15, DDR-60G-15) accept 9-36V DC.
