Adjustable DC Bench Supply

The Shenzhen Sky TopPower STP3010 delivers 0-30 V and 0-10 A for laboratory, repair and DIY electronics work. A three-digit LED display shows voltage to 0.1 V and current to 0.01 A. It operates from 110 V or 220 V AC mains and weighs 2.87 pounds.

Build Integration

Alligator clip leads connect directly to the device under test, so no extra cables are required. Automatic crossover between constant-voltage and constant-current modes lets the unit protect sensitive loads without manual switching. The bench-top footprint of 11.8 by 5 by 7.2 inches fits standard work surfaces.

Thermals and Power

A built-in fan keeps the switching supply quiet while maintaining 85 % overall efficiency. Thermal, current-limit, overload and short-circuit protections engage automatically. The unit is rated for continuous operation from 0 to 40 °C with ripple below 80 mV peak-to-peak on voltage and 3 mA RMS on current.

Questions about this item

At what output voltage and current does the 85 % overall efficiency limit appear?

The unit is rated for 85 % overall efficiency across the full 0–30 V, 0–10 A range.

How much ripple and noise does the built-in fan allow at continuous load?

Ripple and noise are specified as ≤ 80 mV peak-to-peak on voltage and ≤ 3 mA RMS on current.

Which input mains voltage and fuse must already be available on the bench?

The supply accepts 110 VAC ± 10 % at 60 Hz and uses an F6AL 250 VAC fuse.
