Tekpower TP3030E adjustable DC supply

The Tekpower TP3030E is a professional switching power supply that delivers continuously adjustable 0-30V and 0-30A from its main rear terminals. A front auxiliary output provides up to 5A for auxiliary circuits. A large backlit LCD shows voltage and current values with low ripple performance.

Check mains voltage and operating environment

Verify that your bench or lab can provide a 110V AC input for the unit. The supply is rated for operation between 0 and 40C ambient temperature with controlled relative humidity. Ensure the 13 x 3.5 x 8.5 inch footprint fits your available workspace before ordering.

Integrates into test bench with built-in protection

The automatic fan cooling and fuse protection allow extended runs without overheating, while overload and overheat safeguards protect connected loads. The front auxiliary terminals free the main binding posts for primary devices. A user manual and warranty registration card are included in the package.

Questions about this item

What does the package include and do I need separate cables for the rear 30 A output?

The box contains the TP3030E unit, a user manual and a warranty registration card. The rear terminals accept standard banana plugs or spade lugs; supply your own leads for the 0-30 V, 0-30 A main output.

When should I use the front AUX terminal instead of the rear 30 A output?

Use the front AUX terminal for loads up to 5 A where convenient front access helps; switch to the rear binding posts when you need the full 0-30 A range.

What does the 100 mV ripple figure mean for a 30 V rail in practice?

At full 30 V output the worst-case ripple is 100 mV peak-to-peak, which is well below 1 % of the rail voltage and suits most analog, digital and RF prototyping work.
