Possible po ba na makagawa ng Linear Power Supply na 80V 2.5Amps?
Meron kasi mga programmable LPS, pero sigurado ako mahal e. Kaya balak ko po sana malaman kung kaya ba gawin yung LPS na 80V 2.5Amps. or 2Amps man lng
Para sa motor sa robotic arm po gagamitin.

palagay ko kaya pa naman, depende sa availability ng controller at kung ano sira.

Comment on a very good and old topic: Designing and building a programmable benchtop PS.

Maraming great ideas dito sa forum, but there is one thing that was never discussed, at least hindi ko nakita o nabasa.  When you're talking of an output with mVolts involved, i.e. 3.3V, 5.1V, 12.6V or so on, baka pagdating sa business end ng PS cable or usually clips, iba na ang voltage!

A good Power Supply design must have sense inputs so the actual voltage supplied at the load is fed back to the PS unit to adjust the voltage drop on the wires or cable.  From experience, kahit anung galing ng bench lab PS with digital meters, we never trusted their readings.  Parati na lang meron separate DVM to read the actual voltage delivered to the load.

Point to ponder....

Gud day po.

May alam po ba kaung circuits for Dual Complementary Power Supply

Output: above 5 amperes
+/- 15 V above siguro (di binigay eh)

Bwal po IC-IC... preferably transistors
(di pde LM317 at LM7918 pair)

Salamat po.
