Description

The DDR-15L is a compact 15W DIN Rail type DC-DC converter designed for installations powered from 24V or 48V battery and DC bus systems. Its ultra slim 17.5mm (1SU) profile fits standard TS-35 DIN rails, and a 4:1 wide input voltage range of 18~75Vdc covers nominal 24V and 48V DC supplies. With no minimum load requirement, free air convection cooling, and reinforced 4KVdc I/O isolation, the DDR-15L provides reliable isolated power across a -40~+85°C operating range.

Frequently Asked Questions

Can I use the DDR-15L-15 to power a 15V industrial instrument from a 48V DC distribution system?

Yes. The DDR-15L-15 accepts 18-75V DC input and outputs a stable 15V at up to 1A (15W). This makes it well suited for powering legacy 15V instruments, PLCs, or measurement devices installed in systems with a 48V main bus.

Is the DDR-15L-15 a good choice for powering 15V analog signal conditioning boards on DIN rail?

Yes. The DDR-15L-15 provides a regulated 15V output with 4KVdc I/O isolation, which helps protect sensitive analog circuitry from DC bus noise. Its DIN rail mounting and ultra-slim 17.5 mm profile allow it to fit beside signal conditioning modules in tight panel layouts.

Can this converter supply 15V to audio or communications equipment in a vehicle or marine vessel with a 24V or 48V DC system?

The DDR-15L-15 accepts 18-75V DC input, which covers both 24V and 48V nominal vehicle and marine electrical systems. It delivers 15V at 1A, suitable for small communication radios, audio amplifiers, or navigation displays that require a 15V supply.

Can the DDR-15L-15 operate in a freezer room or extreme cold storage environment?

Yes. The DDR-15L-15 is rated for operation from -40°C to +85°C, so it can function in cold storage, freezer rooms, and other extreme temperature environments. It must still be protected from direct moisture contact since it is not IP-rated for water exposure.

Is the DDR-15L-15 suitable for powering 15V test and measurement equipment in a rack-mounted DC power distribution setup?

Yes. With its 18-75V input range and 15V/1A output, the DDR-15L-15 can step down a 48V or 24V rack bus to 15V for test instruments, calibration devices, or lab equipment. The fanless design means it adds no acoustic noise to the test environment.
