Power Supply MEAN WELL DLP-04R

The MEAN WELL DLP-04R is a compact power adapter/inverter designed for low-power applications. It accepts a wide AC input range (90–264 VAC) and provides a regulated DC output of 18.7 V at 0.24 A (4 W output), meeting RoHS requirements. The unit features a slim rail-mount form factor suitable for installations where space is limited.

Advantages

The DLP-04R combines a broad input voltage range with a stable 18.7 VDC output and a small footprint (35 mm × 54.5 mm × 90 mm). Its rail-type housing simplifies mounting in control cabinets and on DIN rails. RoHS compliance ensures the adapter meets common environmental and safety restrictions.

Suitable for

• Powering DALI ultra-slim bus devices and low-power lighting control modules
• Embedded electronics and small control circuits requiring 18.7 VDC at 0.24 A
• Space-constrained installations in control cabinets and electrical panels
