HB24-1.2-AG Power Supply 24V 1.2A - Open Frame Panel Mount

Our review of the HB24-1.2-AG finds it best suited for engineers and builders who need a simple, dependable linear AC-DC module for control panels or embedded systems. The bottom line: this is a straightforward 24V linear power supply that delivers quiet, well-regulated DC output from a broad 100-264V AC input range, and its panel-mount open frame design makes it easy to integrate into existing enclosures. For those prioritizing low electrical noise and compliance with international safety marks, the unit offers predictable behavior and proven ruggedness.

Key Features

• Wide input range: Accepts 100-264V AC so it will operate with most global mains voltages without additional adapters.
• 24V regulated output: Provides a steady 24V DC at up to 1.2A suitable for small controllers, relays, and instrumentation.
• Linear regulation: Uses linear topology to keep output noise and ripple low, benefiting sensitive analog circuits.
• Open frame, panel mount: The combination of open frame construction and panel-mount points simplifies mechanical integration into control panels and industrial racks.
• Proven design pedigree: Built from the Linear Series family with rugged construction and international approvals for safer deployment.

Who It's For

The HB24-1.2-AG is aimed at electronic technicians, industrial integrators, and hobbyists who need a compact 24V supply with low output noise for instrumentation, legacy systems, or panel-mounted equipment. Its linear design makes it attractive when analog stability is more important than maximum efficiency.

It is less suitable for projects where size, weight, or efficiency are the primary constraints, or where convection-free sealed supplies are required; designers who need switching supplies or higher amperage should consider alternate families.

Pros & Cons

Pros

• Low-noise linear regulation that helps maintain signal integrity in sensitive circuits.
• Wide 100-264V AC input range so it works across international mains without modification.
