Test conditions and notes7

1. All parameters NOT specially mentioned are measured at 600Vdc input, 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 ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft).
6. Installation clearances : 40mm on top, 20mm on the bottom, 5mm on the left and right side are recommended when loaded permanently with full power. In case the adjacent device is a heat source, 15mm clearance is recommended.
7. The power supply is considered a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still meets 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 )

FAQ

Can the DDRH-60-48 supply 48V to PoE network switches in industrial Ethernet infrastructure powered from a high-voltage DC bus?

Yes. The DDRH-60-48 outputs 48V at 1.25A (60W) and accepts 150–1500VDC input, making it suitable for powering 48V PoE switches or injectors in industrial Ethernet networks where the source bus is a high-voltage DC system.

Is the DDRH-60-48 suitable for powering 48V DC fans, drives, or cooling systems in process control enclosures?

At 60W and 1.25A on a 48V rail, the DDRH-60-48 can supply 48V cooling fans and small 48V DC loads used in process control enclosures that receive power from a high-voltage DC distribution bus.

Can the DDRH-60-48 be deployed in traction or rail environments with varying DC link voltages?

The 150–1500VDC input range covers DC link voltages such as 600V and 750V DC, and the unit operates from –30°C to +80°C (with derating, see the derating curve). The sheet lists no railway standards (only UL1741, CSA C22.2 No.107.1-16, IEC62109-1 and EAC), so check compliance for rolling stock use.

Does the adjustable output on the DDRH-60-48 allow fine-tuning for battery float charging at 48V?

The output voltage is adjustable from 48V to 54V, with constant current limiting at 105–135% of rated power. The sheet does not specify a battery charging function, so confirm the float voltage your 48V battery bank requires falls within this range.

Is the DDRH-60-48 appropriate for installation in outdoor roadside or utility cabinets?

The unit operates from –30°C to +80°C (with derating at higher temperatures) with a 57mm slim-width design suited to compact outdoor enclosures. No IP rating is stated for the unit, so the external enclosure must provide rated environmental protection.

How does the DDRH-60-48 compare to the DDRH-60-12 and DDRH-60-24 in the same series?

All share the 150–1500VDC input and 57mm slim-width form factor, and each has an adjustable output. The DDRH-60-48 provides 48V at 1.25A (60W, adjustable 48–54V), versus 24V at 2.5A (24–29V) for the DDRH-60-24 and 12V at 5A (12–15V) for the DDRH-60-12.
