Hi Guys, need the community wisdom!
I am looking for a professional grade lab power supply:
- (must) low ripple & noise ( around < 3 mV)
- (must) high current, >20Amp @ 5V, >15Amp @ 12V (200W per channel should be plenty)
- Don't really need more than 20V output per channel
- (must) Precision adjustment of voltage and current
- (must) all the usual bells and whistles, like constant current, constant voltage, etc
- (must) very stable at low voltages and high currents (for example 0.65V 18A)
- (very important) would like to have at least 4 channels, or capability of chaining multiple units
- (must) must be able to program inter channel power sequence (including delay)
- (very important) Programmable emulation of noise and ripple would be nice
- (nice to have) parallel channel operation to increase current
- (nice to have) serial channel to increase voltage
- (nice to have) remote sensing
So far, I could only find one that meets all my requirements: Rohde & Schwarz NGP804.
But it has quite a hefty price tag at around $5,500 USD for this configuration (NGP804).
Before I drop that kind of cache, I'd like to hear alternative suggestions from all you wise people!
Merry Christmas & Blessed Hanukkah, to those who celebrate!
