A non common but usefull tool for every laboratory is an adjustable power supply, high quality & stability were approved.
When i decided to design this device i was very lucky, a friend of mine came with a damaged one & he ask me to fix it, i took the risk to re engineer it
but as i wrote several times before i’m going to be a whole-hog nerd when i’m going to sign a device, my first thought is always safety & a good MTBF.
A RACK MOUNT 19” 300W PSU 0-30V/0-10A designed (case, pcbs, & panels) for laboratory use, but with a high difficulty constructive level.
Designed for hard working conditions, with over temperature, current & power failure protections.
Specifications
Voltage Supply: 110V-220V 50-60Hz (depend on country region)
Output Voltage: 0-30V DC With step less than 0.1V (full range scale)
Output Current: 0-10A DC
Protection
– Current limitation
– Over temperature protection at 70C
– Short Circuit Protection
– Soft Start Input protection circuit.
Indicators
– Over Temperature with LED
– Fuse failure Indicator with LED
– Over current limitation with LED
Power Consuption 300W max
Ripple Max: 0.2mVrms
THIS PROJECT IS NOT FOR SALE.

For several times in the past i push myself to work with a medium power lab psu with voltage & current range over 50V & 10Amps.
I must be honest with my self it was a boring proccess…let me to explain what i mean,
sometimes i fell like a whole-hog nerd & when i’m trying to design or to improve an old design this can transform me to a workalcoholic strange guy.
Yes, i spend over a month into my lab to design a solid state device with excellent performance & stability.
