Tekpower

Tekpower TP1863 12 A 13.8 V regulated power supply measurement tool

SKU CH-7D4M-FC9K3

Regulated 13.8 V DC bench supply delivers up to 12 A with ripple at or below 30 mV from a 110 V 60 Hz input

  • Delivers stable 13.8 V DC for sensitive electronics
  • Low ripple ≤ 30 mV keeps signals clean
  • Adjustable 10–12 A output matches load demands
  • Runs on standard 110 V 60 Hz mains
  • Compact 5.5 × 4.3 × 10 in bench footprint

Tekpower TP1863 bench supply

The Tekpower TP1863 is a regulated DC power supply delivering 13.8 volts at up to 12 amps. It suits hobbyists, technicians and automotive workshops needing stable voltage for testing radios, chargers or 12 V systems. Fuse protection guards the output against accidental shorts.

Check 110 V 60 Hz mains before use

Verify that the bench or workshop outlet supplies 110 V AC at 60 Hz, as the unit does not accept other line voltages. Ensure the load you connect does not exceed the 12 A maximum rating. Confirm that 13.8 V matches the voltage requirement of the device under test.

Metal chassis with front binding posts

The steel enclosure measures 5.5 by 4.3 by 10 inches and weighs 9 lb, giving a stable footprint that resists sliding when leads are tugged. Front-panel binding posts accept banana plugs or bare wire for quick hook-up. Ripple stays at or below 30 mV for clean DC output.

Questions about this item

What comes in the box with the TP1863 and do I need to buy a mains lead separately?

The unit ships with a built-in 110 V AC 60 Hz input cord and internal fuse protection so no separate mains lead is required.

Should I rely on the 10 A continuous or the 12 A peak rating for my load?

Plan for 10 A continuous; the 12 A figure is a short-term maximum and sustained loads above 10 A may trip the internal fuse.

How much does the 30 mV ripple affect sensitive radio or audio gear powered at 13.8 V?

At ≤ 30 mV ripple the output is clean enough for most HF/VHF transceivers and bench work, though ultra-low-noise audio stages may still prefer a linear supply.
