Product Usage Instructions

To use the DDRH-120 DC-DC converter, follow these steps:

Select the appropriate model based on your required output voltage and current.
Ensure that the input voltage falls within the range of 250~1500Vdc and that the external input fuse is properly installed.
Connect the input terminals to the DC power source and the output terminals to your load device.
Adjust the output voltage if necessary using the voltage adjustment range.
Power on the converter and monitor the DC OK relay contact to ensure proper operation.

Note that the DDRH-120 DC-DC converter has various protections in place to prevent damage to the device or connected devices. In the event of a short circuit, overload, over voltage, over temperature, or DC input under voltage/reverse polarity, the converter will enter hiccup mode and shut down until the issue is resolved.

EMC EMISSION

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 http://www.meanwell.com)
