How to use

Mount the DDR-30L-5 on a standard DIN rail inside the control cabinet and connect the DC input to a suitable 18–75 V supply, observing correct polarity. Connect the 5 V DC output to the load, ensuring the total current draw does not exceed 6 A. Provide appropriate fusing and observe wiring practices to avoid voltage drops; ensure adequate ventilation around the module according to installation guidelines.

Recommendations

For reliable operation, use the converter within its input voltage range and keep the output current below the rated 6 A. Protect the input with a suitable fuse or circuit breaker, and place the device on a DIN rail in a ventilated enclosure away from heat sources. Refer to the manufacturer's datasheet for detailed thermal and mounting limits.
