## Summary description

Assembled voltage regulator board from H-TRONIC (MPN 130312) built for the LM317-T adjustable regulator. Provides an output voltage range of 1.2–32 V DC and includes the mounted regulator and necessary board components for bench or embedded power-supply applications. Suitable for prototyping, repair, small lab supplies and custom electronics where a compact adjustable DC source is needed.

## Long description

Assembled voltage regulator board H-TRONIC 130312 is built around the adjustable LM317-T regulator and provides a compact, ready-to-use solution for generating a stable DC output between 1.2 and 32 V. The unit includes the mounted regulator and all necessary passive components on a small printed circuit board, making it suitable for bench power supplies, prototypes, repairs and embedded applications where a compact adjustable voltage source is required.
Advantages
The assembled board saves time compared with building a regulator circuit from separate parts and ensures correct mounting and spacing for the LM317-T in TO-220 format. It offers a wide output voltage range from 1.2 to 32 V and supports currents up to 1 A, enabling use with a variety of low-power circuits. The compact PCB (approximately 31 mm × 50 mm) and included detailed assembly and usage instructions simplify installation and integration into projects.
Suitable for
 Bench power supplies for hobbyist and laboratory use
 Prototyping and electronics development
 Repair and replacement of defective adjustable power modules
 Embedded devices requiring a small adjustable DC source
Key specifications
 Output voltage range: 1.2–32 V DC
 Maximum output current: 1 A
 Maximum permissible input voltage: 25 V AC (or corresponding DC)
 Regulator type: adjustable linear regulator (LM317-T) mounted in TO-220 format
 PCB dimensions: approx. 31 mm (width) × 50 mm (length)
 Includes mounted regulator and required passive components
 Delivered as an assembled unit with documentation
How to use
Connect the input terminals to a suitably rated unregulated DC or AC source within the specified input voltage range, observing polarity for DC connections. Adjust the output voltage with the on-board potentiometer or adjustment points until the desired output is reached, and verify voltage and current limits with a multimeter before connecting sensitive loads. Secure the TO-220 regulator to a heat sink if the application approaches the maximum current or if prolonged operation at elevated dissipation is expected.
Usage recommendations
For reliable operation, keep the input voltage at least a few volts higher than the required output to maintain regulation headroom, and ensure adequate cooling when drawing currents near 1 A. Use short, low-resistance wiring and suitable protection (fuses or current limiting) for connected circuits. Refer to the included documentation for detailed mounting and safety information.
