Benchtop DC Power Supply

After the DMM and Logic Probe we have DC Power supply as an Essential Workbench Instrument for the Electronics Aspirant. Hobby or Engineering; we need tools to get the job done.

Now you can drool on a vintage power supply with an Analog Dial Meter and Rotary Knobs with Push-Button Selector Switches.

Benchtop DC Power Supply

Small Variable power Supply

Features: 1.3-12.2 V, 1 A, over-current protection. This is a simple but reliable device based one of the oldest integrated voltage regulators of them all - the LM723.

Power Supply Adjustable 0V-30V DC/2A

It is a simple circuit regulated power supply, based on the known LM 723, that drive a transistor Q1 [2N3055]. The regulation of voltage, of expense becomes with potentiometer R1 from 0v-30v DC roughly. In order to we achieve 30 V,...

Build A 10 Amp 13.8 Volt Power Supply By N1HFX

Sometimes amateurs like to home-brew their power supplies instead of purchasing one off the shelf at any of the major ham radio retail dealers. The advantage to rolling your own power supply is that it teaches us how they work and makes it easier to troubleshoot and repair other power supply units in the shack.

delabs Notes

Always remember Amateur Radio Operator or Ham is an highly skillful, professional and prudent design engineer. A qualification is not to be valued in Engineering, it is the Practical Problem Solving abilities that some people posses.
