Adjustable DC Bench Supply

The TekPower TP3010HB is a professional regulated DC power supply built for lab, service and hobbyist bench work. It delivers continuously adjustable output from 1 to 30 volts and 0 to 10 amps with independent voltage and current controls. A built-in USB port adds convenient charging for mobile devices. A dedicated charge mode supports precise battery charging tasks.

Thermals Noise and Power Draw

The switching design operates from a 110 volt input and meets ripple noise of 100 mVp-p or less under constant voltage regulation. Line regulation is held within 1 percent plus 3 millivolts while load regulation stays within 1 percent plus 5 millivolts. The unit is rated for an operating environment of 0 to 40 degrees Celsius at relative humidity below 80 percent.

Build Integration and Clearances

Measuring 3.4 by 9.5 by 7 inches the supply fits on a standard bench or shelf without special mounting. The front-panel LCD gives clear voltage and current readouts so external meters are not required for basic monitoring. The single USB output frees a separate charger for phones or small USB devices during test sessions.

Questions about this item

How do I connect the load to the TP3010HB, and what wiring mistake trips the current limit?

Wire the load to the front binding posts, set the voltage first, then dial the current limit up from zero; reversing this order makes the supply hit the 0-10 A limit instantly and shut down.

Which part of the TP3010HB will need replacement after heavy use, and how often?

The internal cooling fan is the only moving part; expect to replace it every few years if the unit runs near 10 A in a 40 °C ambient.

At what point does the TP3010HB hit its thermal limit during a long 10 A run?

Continuous 10 A output in a 40 °C room will trigger the over-temperature protection first; the supply will shut down until the heatsink cools.
