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-24 to step down a 48V DC bus to 24V for PLC and automation equipment?

Yes. The DDR-60L-24 accepts 18-75V DC input, covering 48V nominal buses. It outputs 24V at 2.5A (60W), which is a standard supply voltage for compact PLCs, relays, solenoid valves, and 24V field devices commonly used in factory automation panels.

Is the DDR-60L-24 a good fit for powering 24V building automation controllers from a 48V DC backbone?

Yes. Building management systems often distribute 48V DC along cable trays and then convert locally to 24V for controllers, actuators, and sensors. The DDR-60L-24's 60W capacity and compact 52.5 x 90 x 54.5 mm size make it straightforward to install at each local panel. Its 4KVdc I/O isolation separates downstream equipment from the bus.

Can the DDR-60L-24 supply 24V power to a small Modbus RTU network of field transmitters?

Yes. Most 4-20mA loop-powered or Modbus RTU transmitters draw well under 1A each at 24V. With 2.5A available, the DDR-60L-24 can power multiple transmitters on a shared 24V rail. The 4KVdc I/O isolation keeps the 24V rail separated from the upstream DC bus.

Is the DDR-60L-24 suitable for converting 48V telecom power to 24V for edge networking gear?

Yes. Telecom sites commonly provide -48V DC (referenced as 48V magnitude). The DDR-60L-24 accepts up to 75V DC input, comfortably accommodating telecom bus voltages including float-charge levels. It delivers 24V at 2.5A for switches, small routers, or PoE injectors rated at 24V input.

Can the DDR-60L-24 operate in a non-ventilated weatherproof enclosure exposed to temperature extremes?

The DDR-60L-24 has an operating range of -40°C to +85°C, with output derating at higher temperatures per the datasheet's derating curve. Its compact 90.0 x 54.5 x 52.5 mm profile fits easily in sealed NEMA or IP-rated enclosures. Verify that worst-case enclosure temperature and your load stay within the derating curve.

What DDR-60L models are available if I need a different output voltage?

The DDR-60L series offers four output options, all with 18-75V DC input: 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 share the same 52.5 x 90 x 54.5 mm size and 4KVdc I/O isolation.
