Test conditions and notes6
- 1. All parameters NOT specially mentioned are measured at normal input (G:24Vdc, L:48Vdc), rated load and 25℃ of ambient temperature.
- 2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1μF & 47μF parallel capacitor.
- 3. Tolerance : includes set up tolerance, line regulation and load regulation.
- 4. Derating may be needed under low input voltage. Please check the derating curve for more details.
- 5. The power supply is considered as an independent unit, but the final equipment still need to re-confirm that the whole system complies with the EMC directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.” (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf )
- 6. The ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft).

FAQ
Can I use the DDR-60L-12 to step down a 48V DC bus to 12V for surveillance cameras in an industrial facility?
Yes. The DDR-60L-12 accepts 18-75V DC input, which covers standard 48V DC distribution buses. It provides 12V at 5A (60W), enough to power several IP cameras, or one PTZ camera with heater, directly from the DIN rail panel.
Is the DDR-60L-12 a good choice for converting a 24V solar battery system to 12V for radio or networking equipment?
Yes. A 24V nominal battery system typically ranges from about 20V to 29V under charge, which falls within the DDR-60L-12's 18-75V input window. At 60W it can power 12V routers, switches, or radio transceivers commonly used in off-grid or remote monitoring setups.
Can the DDR-60L-12 power 12V LED lighting strips inside a DIN rail-controlled display case?
Yes. With 5A at 12V the DDR-60L-12 delivers 60W, which can drive several meters of standard 12V LED strip depending on the strip's power per meter. The 4KVdc I/O isolation separates the LED circuit from the upstream DC bus.
Is the DDR-60L-12 suitable for use in a vehicle or mobile equipment with a 48V electrical system?
The DDR-60L-12 accepts 18-75V DC, which covers a 48V nominal system as long as the bus stays within that window. It has a -40°C to +85°C operating range (with derating per the derating curve), components are vibration-tested at 10-500Hz, 2G, and mounting complies with IEC60068-2-6; confirm these limits suit your vehicle's conditions.
Can the DDR-60L-12 operate reliably in a freezing cold outdoor junction box?
Yes. The DDR-60L-12 is rated for operation from -40°C to +85°C, so it handles extreme cold without issue. It has no stated IP rating and is specified for 5-95% RH non-condensing, so the junction box must keep out water and condensation.
What output voltage options are available in the DDR-60L series?
The DDR-60L series includes four models sharing the same 18-75V input range and 52.5 x 90 x 54.5 mm size: DDR-60L-5 (60W, 5V, 12A), DDR-60L-12 (60W, 12V, 5A), DDR-60L-15 (60W, 15V, 4A), and DDR-60L-24 (60W, 24V, 2.5A). All feature 4KVdc I/O isolation.
