The DDR-60L is a 60W DIN Rail type DC-DC converter with a 52.5mm (3SU) profile, designed for systems fed from 24V or 48V DC sources. A 4:1 wide input voltage range of 18~75Vdc covers both nominal 24V and 48V DC bus supplies, while reinforced 4KVdc I/O isolation ensures noise-free power delivery. Free air convection cooling and no minimum load requirement make it simple to deploy across a -40~+85°C operating range.

Frequently Asked Questions

Can I use the DDR-60L-15 to power 15V industrial sensors from a 48V DC distribution bus?

Yes. The DDR-60L-15 accepts 18-75V DC input, which covers standard 48V buses. It outputs 15V at up to 4A (60W), making it well suited for powering arrays of 15V industrial sensors, transducers, or measurement instruments mounted on DIN rail in control panels.

Is the DDR-60L-15 suitable for providing isolated 15V power to analog signal-conditioning boards in a process control system?

Yes. The 4KVdc I/O isolation prevents ground loops and noise coupling between the 48V or 24V source bus and the sensitive 15V analog circuitry. At 60W and 4A it has headroom for multiple signal-conditioning modules that typically draw a few hundred milliamps each.

Can the DDR-60L-15 convert a 24V battery bank to 15V for laboratory bench instruments?

Yes, provided the battery voltage stays within the 18-75V input range. A 24V lead-acid bank typically sits between 20V and 29V, which is well within spec. The DDR-60L-15 delivers a stable 15V at up to 4A, suitable for test instruments, data loggers, or bench-top devices in mobile labs.

Will the DDR-60L-15 function in a high-temperature rooftop telecom enclosure during summer?

Yes. It is rated for operation up to +85°C ambient temperature. Its fanless design means there are no fans to clog with dust or debris in rooftop environments. However, ensure the enclosure does not exceed the +85°C limit under direct solar load.

Can the DDR-60L-15 handle sub-zero temperatures in an unheated utility cabinet?

Yes. The operating temperature range extends down to -40°C, so it will start and regulate properly even in extreme winter conditions. The solid-state fanless construction avoids any mechanical startup issues common to fan-cooled converters in freezing environments.

How does the DDR-60L-15 compare to the DDR-60G-15 in terms of input voltage range?

Both output 15V at 4A (60W) and share identical dimensions of 90.0 x 54.5 x 52.5 mm. The key difference is input range: the DDR-60G-15 accepts 9-36V DC (suited for 12V or 24V source buses), while the DDR-60L-15 accepts 18-75V DC (suited for 24V or 48V source buses). Choose based on your upstream DC voltage.
