TBK-217A Curved DC Power Supply

TBK-217A Curved DC Power Supply

The TBK-217A Curved DC Power Supply is a high-performance regulated power tool designed for electronics technicians, mobile repair professionals and diagnostic labs. Combining a stable 20V/5A adjustable DC output with a real-time curve display of voltage and current, it helps you visualize circuit behavior and quickly identify unstable or faulty circuitry during board repair tasks.

With three programmable memory channels, you can save frequently used voltage and current settings for quick recall, streamlining repetitive test routines. The unit also includes a dedicated short-circuit repair function that assists in locating and resolving shorted components on motherboards or PCB assemblies with controlled power application.

The TBK-217A’s one-click output safety control prevents accidental power application, while multiple interfaces — including USB-A and USB-C fast-charging ports and an oscilloscope probe input — make it versatile for both repair and device charging tasks. Compact, reliable and precise, this power supply is ideal for every modern electronics workbench.
