Power supply
Adjustable power supply 0 - 30V / 1A
This power supply deliver a cc voltage adjustable between 0 and 30V , a current intensity of 1A and has a built in programmable current limitation. The output current can be adjusted with P3.
Power supply first use adjustment:
Load the output with a 1k / 1W resistor, rotate P3 at minimum and adjust P2 [...]
AM modulated power supply
A power supply with a modulated voltage output is required for modulation of AM transmitters final stages, Gunn diodes in gigahertz domain. This AM power supply delivers 6V to 8V in repose ( adjustable with P1 ) and between 3V and 10V when it is modulated. Frequency domain is from 200Hz to 30KHz.
Without any load [...]
Stabilized adjustable power supply 0-15V / 5A
This regulated power supply can be adjusted between a few volts and 15V with P1 and with P2 adjust the upper limit ( 15.0V ). R6 value is 0.7V / Imax where Imax is the maximum current. At Imax = 5A, R6 is 0.14Ω
T1 and T2 must have heatsinks because power losses are great at [...]
