Purchased the module, for use as regulated power supply at 32V.
But, unfortunately, the module cannot work at 32V, as the trimmer is running very hot when tuned at 32V, and on top, the electrolytic capacitors C3 and C4 are 25V types.
The operating voltage voltage at C4 is simply the output voltage.
When the VR trimmer is set at 32V, the voltage on VR is 27V, and VR is in that position abt 300 ohms : 2,5W dissipation is much too high...
To solve the problem, I adapted the module as follows:
Changed C3 and C4 by 64V types, and replaced R1 (50 Ohm) by 500 Ohm.
The module can now be easily tuned at the desired voltage, without burning the 5k trimmer, and blowing the elco's.
