I have 1 x 230Vac/2x60Vdc-12,5Adc toroidal lineary power supplie, but i`m considering bying one more and an alternative installation.
They are to be used in my VMC300 mill conversion with 3 pcs NEMA34 640 oz-in 4.5A Stepper Motor, 1 pcs NEMA23 282oz-in 3.0A and 4 pcs Leadshine AM882 drivers.
..
Frankly, i`m not sure 1 PSU is enough. Datasheet says 58,2V at 0 load, 47,9V at 21 Amps/1,7Vrms ripple.
..
Can i install 2 of these in parallell (Both output in parallell after each rectifier bridge/capacitors)?
Or would it be a better solution to install them in parallell with a common(shared) rectfier brigde and capacitors?
The PSU is equipped with 2 pcs 10000uF/80V capacitors, vs my old 85V PSU which is equipped with dual 33000uF/63V capacitors.
Using all 4 capacitors would increase capacity, but might not be a good idea...
..
Any hot advice gents ?
