Fonte de alimentação/inversor MEAN WELL UHP-750-48 — 750 W, 48 V, entrada 90–264 V, 100×237×41 mm

MEAN WELL UHP-750-48 is a compact 750 W AC‑DC power adapter/inverter designed to deliver a stable 48 V DC output for industrial and telecommunications equipment. The unit accepts a wide AC input voltage range of 90–264 V, incorporates power factor correction (PFC) and a DC OK signal for system monitoring, and is housed in a metal enclosure sized 100×237×41 mm. The slim single‑output design supports continuous power delivery and is intended for installation in racks or enclosures where reliable 48 V supply is required.

Advantages

The UHP-750-48 combines high output power with a small footprint, enabling installation in space-constrained environments. With built-in PFC and DC OK signalling, it supports improved power quality and easy integration into monitoring systems. The metal housing provides mechanical protection and heat dissipation appropriate for industrial and telecom use, while RoHS compliance ensures adherence to environmental standards.

How to use

Mount the unit inside a suitable rack or enclosure following applicable safety standards and ventilation requirements. Connect the AC input to an appropriate mains supply within 90–264 V AC, observing correct polarity and protective grounding. Connect the 48 V DC output to the load ensuring the combined current draw does not exceed 15.7 A. Use the DC OK signal for integration with system monitoring or alarm equipment. Follow manufacturer guidance for wiring, fusing and protective devices to ensure reliable operation.

Recommendations

Install the power adapter in a ventilated location and provide adequate clearance for airflow. Use overcurrent protection on the DC output and a dedicated earth connection on the input side. Regularly inspect connections and ambient temperature to maintain performance and longevity.
