HW-AC-ENC-30W-12
30 W enclosed AC-DC switching power supply with universal mains input and 12 V output for equipment and systems.
The HW-AC-ENC-30W-12 is a Hawun enclosed AC-DC switching power supply that delivers 30 watts at 12 volts from a universal mains input covering 85 to 264 volts AC, in a chassis-mount package for equipment and systems. It converts mains power into a regulated 12 volt rail for industrial and commercial equipment, and the enclosed format suits products that need a supply with its own housing and terminals rather than a board-level module. The universal input covers the common worldwide mains range, so one design serves several markets, and the switching conversion delivers high efficiency and a small size. Because the supply is connected to the mains, its isolation and its creepage and clearance are safety-critical, and the input protection and the thermal design must suit the enclosure and the load. The 12 volt output is a common rail for relays, sensors and small actuators, which makes the supply a practical choice for control equipment. Every device is factory-traceable and ships with an import declaration, a certificate of origin and RoHS documentation. BeiLuo holds this part in regional stock and our FAE team supports supply selection, thermal design and safety review.
FAE Professional Review
This is the enclosed supply we recommend for equipment that needs a 12 volt rail from the mains with its own housing and terminals. The universal input simplifies worldwide products, and the enclosed format suits panel and chassis mounting. Size the supply for the peak load with margin for the derating at high temperature, and confirm the isolation and creepage for the standard the product must meet.

Frequently Asked Questions
How do I choose the output power?
Size the supply for the peak load with margin for transients and for the derating at high temperature, rather than for the average load.
Confirm the derating curve against your enclosure and airflow.
Is the enclosed format easier to integrate?
Yes. The enclosed supply has its own housing and terminals, so it can be mounted in a panel or chassis without the creepage and clearance design a bare board would need.
Confirm the mounting and the terminals for your system.
