JLM TREX simple reg kit is a very simple Linear based universal power supply with can generate a 5v to 28v from a single 30v to 48vdc rail.
It can do other output voltages by changing to different voltage zeners or if running from a regulated higher rail a trim pot can be used in place of the zener.
Using on of the 48v 380mA SMPS prebuilt supplies and a TREX or TREX2 kit is the easiest and cheapest way to power 2 x 1073 , 1290, 1272 neve modules.
Or 2 x V672 modules etc that need 24v to run and 48v rail for phantom power. Because there is no power transformer involved there is no hum problems due to coupling to the audio transformers.
Regulator is on one edge for easy heatsink or case mounting.
Can supply 1amp
The TREX PCB is 1.2" wide (28mm) x 1" deep (25mm) x 1.1" (28mm) high from top of tallest cap to lowest solder joint under the PCB.
