This is a simple, but low-ripple powersupply

4 ampere regulatable power supply 1 - 15volt RE-PSR4A18

A standard LM723 Voltage Regulator and some darlington pass transitors

This is an easy to make power supply which has stable

I wanted a compact but powerful and versatile power supply

Linear power supplies for communication equipment

Developing a power supply providing 15 VDC or less

this project describes a protected 13.1V POWER SUPPL

This device is based on the "good old" LM723, UA723 e.a. It uses 4 diodes which form a bridge rectifier

It's a stabilized power supply (13V variable-5A) with protection

This is the primary Power Supply for my Amateur Radio Shacks transceiver equipment. The Power Supply is build around the LM723 controller and four BUZ24 (or IRF150)

Both meters were stuck up scale and totally useless

this adjustable voltage regulator is made by combining a common 78l05 with an integrated audio amplifier of the type tda2030

costruito volutamente con materiale di recupero

Astron RS35m Power Supply Schematic, AL7FS

The LM317 is one of the most popular voltage regulators

repeater-builder about replacing the analog meters with digital meters

Amateur radio has been somewhat slow to accept switching power supplie

A linear power supply takes the 120vCA 60 Hz mains power, steps the voltage down through a transformer, rectifies, filters, and regulates it

A completed 145 watt ATX power supply with switch, binding posts

12V (or 13.5v) PSUs with enough wattage to supply

This page describes a DC to DC voltage converter

remember that the 2n3055 transistor need reasonable

have used this one in two homebrew-modem, for an hamcomm

As you see, this scheme permits to use IC-E90 with normal power supply

I got a new PS-125 when I purchased a new IC-746PRO

diciamo, 32V. In caso di alimentatore non stabilizzato, la nostra

This article is based on my personal experience fixing these supplies

This is an easy to make power supply which has stable

radios, and power amplifiers, are requiring the use of 28 Volts

uninterruptible power supplies for computer solid state switching circuitry the transformer by itself can be easily re-purposed to produce low voltage AC point for a high current low voltage DC power supply

This PS-Unit is constructed for the use with 100Watt transceivers

Late one Saturday night I needed a variable DC supply

Home-brew 13.8 Volt Power Supply

It is a 12 volt linear voltage regulato

Come e' noto il power supply ATX serve per convertire l'energia 220V

The purpose of this project is to build a smart switch

electronics workroom has a decent regulated 13.8 volts DC 10A
