Test conditions and notes7

1. All parameters NOT specially mentioned are measured at 800Vdc 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-240-24 power 24V automation equipment such as PLCs, servo drives, or solenoid valves?

Yes. The DDRH-240-24 outputs 240W at 24V and 10A, which covers the power needs of typical 24V industrial automation components including PLCs, servo drive controllers, and solenoid valve banks. Its DIN rail form factor allows it to mount directly alongside the equipment it powers in a control panel.

Is the DDRH-240-24 suitable for use in DC microgrid or high-voltage DC distribution systems?

Yes. With a 250–1500VDC ultra-wide input range and 6:1 ratio, this converter is designed for high-voltage DC sources such as DC microgrids, solar arrays, and battery storage buses. It also has input reverse polarity protection and under-voltage lockout (200–230VDC); an external 4A/1500VDC input fuse is required.

Can I use the DDRH-240-24 to power 24V industrial sensors and field instruments?

Yes. At 240W and 10A, the DDRH-240-24 provides ample capacity to supply multiple 24V sensors, transmitters, and field instruments simultaneously. The output voltage is also adjustable from 24V to 29V, which can accommodate loads with slightly higher voltage requirements.

What temperature range does the DDRH-240-24 support, and is it suitable for cold storage or extreme-heat environments?

The DDRH-240-24 is rated for -40°C to +80°C operation, with output derating at higher ambient temperatures per the derating curve, covering both cold storage facilities and high-ambient industrial environments. No IP rating is listed for the unit itself, so it should be installed in an appropriately sealed enclosure when deployed in wet or dusty conditions.
