Low-voltage DC power supply, nominal output 12–48 V, rated current 20 A, rated power 1000 W. Power increases with output voltage. Key benefits Reliable high-current output for workshop and DIY tasks requiring controlled DC power. High rated power (1000 W) supports rapid heating and consistent performance across the 12–48 V range. Practical for small-part heat treatment: annealing, rapid heating and subsequent quenching. Performance and specifications Output voltage range: 12–48 V DC (nominal). Rated current: 20 A. Rated power: 1000 W (note: power rises with higher voltage within the nominal range). Tested behavior: when operated at 53 V (beyond the nominal range) the unit produced currents up to 30 A in our tests. How this solves problems Provides a stable, controllable DC source for heating elements and small resistive loads, enabling repeatable heat-treatment steps such as annealing or preparing parts for quenching. Delivers enough current and power to heat small metal components quickly, reducing process time and improving workflow in a home workshop or small fabrication environment. Wide voltage range increases compatibility with a variety of DC equipment and heating setups within the 12–48 V domain. Practical applications DIY heat treatment: heat small parts for annealing, tempering or quenching in home metalworking projects. Rapid heating: fast warm-up of small heaters or fixtures used in laboratory or hobby tasks. Workshop supply: a dependable DC source for heating-related experiments and small-scale thermal processing. Notes Specifications reflect nominal ratings: 12–48 V, 20 A, 1000 W. Test data mention operation at 53 V producing up to 30 A. Respect the nominal voltage and current ratings for routine, safe operation.
