This power supply is made for COB LED boards, and provides constant current up to 1750mA from 10-28VDC. Features 0-10V voltage control dimming, thermistor feedback, and a separate 5-12V 2W output for a cooling fan. Has full pinout on the case. Works perfectly as a driver for COB LED lighting boards. Like these. Click! Measures 5-5/8" x 3" x 1-3/8". RoHS compliant. UL.

Can you plug in a banana? You can when you have a pair of 34” black and red leads with banana clips on one end. And these have alligator clips on the other end, so you can also plug in your reptiles, too.

This MW® regulated power operates on 120 VAC and delivers constant accurate power to a video game, radio, portable TV, or any device drawing up to 2.0 amps. The 5 1/8" x 3-7/8" x 2-5/8" housing has a rotary dial to designate 3, 4.5, 6, 7.5, 9 or 12 VDC output, and heavy-duty red and black binding posts. Automatic short circuit and overload protection and thermal cutoff. Add the mini plug kit or the alligator test clip leads. The mini plug kit contains six of the most popular DC plugs for DC powered devices such as portable TV sets, video games and radios. "Gator" clips are 36" long with one red and one black lead.

Not to be confused with Flower Power (or Flour Power, the failed Patisserie Party movement), this floor-mount power supply, likely from a lighting fixture. 115VAC supply is rated 2.5A at 12VDC. Has a 6-foot, 18-3AWG grounded power cord and a 6-foot output lead terminating at tinned wire ends. A great unit!

Hey, electronics wizards! This home lab device has your name all over it. Actually, it has the Velleman® name all over it, but it’s an all-in-one workbench with a power supply, multimeter and soldering iron station. Gives us a little jolt just thinking about it! Has a footprint of 15” x 6” with a 1.5A regulated 3-12VDC power supply (2A peak), a digital multimeter that will read from 200 to 2M Ohm, AC from 0-200 or 0-600V, DC from 200MV to 600V and 200uA to 10A. Also tests diodes and transistors, plus continuity via a backlit 1-3/4" LCD, and a 24V 48W temp. controlled ceramic element soldering station has a variable 150°-450° Celsius (300°-840°F) range. Comes with a power cord, leads, iron stand, sponge and spare element. Tips are 1.6 mm round. A very solid piece of machinery in a compact package.

Don’t miss your chance to upgrade your workbench with this Velleman DC lab power supply with dual LCD displays. Can be used as both a constant voltage and constant current source with rated outputs of 0-30VDC at up to 3A max, and is overload protected. Precisely control your tests with coarse and fine-tune controls and easy-to-read digital displays.

These switching power supplies--called Mini Universal Notebook Adapters by their manufacturer, Velleman®--are smaller, produce less heat, have stabilized output, short circuit and overload protection. They put out up to 4.7A at 18-19.5VDC with ripple noise reduction via a 4-foot choked, non-polarized shaver cord. Measure 4-1/2" x 2-5/8" x 3/4". You pick: The power supply alone has a plug that the manufacturer says incompatible with Apple products--notebooks, phones, iPads, etc.; the Adapter Plus also includes a pack of plugs for Dell and HP.

Absolutely not. Especially with these 100-120VAC input regulated switching power supplies with trim pots to adjust the output 0.5V either way, vented housings, 5-pole terminal blocks for AC in, chassis ground and DC out. You pick the 5A at 5VDC unit at 3-7/8" x 4" x 1-3/8" or the 8A at 5VDC at 5" x 3-7/8" x 1-1/2". Both have 3/32" mounting holes and are CE listed.
