Build a 13.8V, 40A Switching Power Supply
- In this article I will describe the construction of a switching power supply designed to power a complete ham station, with several radios and accessories. This power supply produces 13.8V regulated to better than 1%, at a continuous load current of up to 40A

Portable 28 Volt DC Power Supply
radios, and power amplifiers, are requiring the use of 28 Volts
High power low voltage variable DC supply
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
Power supply from 3 to 30 V with an L200 IC
This PS-Unit is constructed for the use with 100Watt transceivers
