How to use

Mount the converter on a standard DIN rail inside the control cabinet or enclosure. Connect the input terminals to a suitable 16.8–33.6 Vdc source following polarity markings and ensure proper fusing according to system requirements. Connect the 24 Vdc output to the load, observing maximum current limits. Provide adequate ventilation and follow MEAN WELL’s wiring and grounding recommendations as found in the product manual.

Recommendations

Use appropriate input protection (fuse or circuit breaker) sized for the application, keep ambient temperature within the specified range, and avoid mounting near heat-generating components to maintain reliable operation. For detailed installation and safety instructions refer to the manufacturer datasheet.
