Do you guys think this would work as a poor man's linear power supply for the pulse? or waste of time? It says it does 12v 1.25 amps.. the transformer is only 7.5va though.. the real lps has a 30va one and is 12v 800ma. also not sure what size power tip the pulse will need
the real LPS specs are:
110V/120V or 220V/240V 50/60 Hz AC input.
12V DC, 800mA output (uses the notoriously good power supply technology inside Da Vinci DAC)
5V DC, 500mA output in front panel via USB-A connector (Can be used with Geek Out via split USB cable to reduce power noise from computer.)
47,000uF Reservoir Capacitor (4700uF * 10) with zero switching off noise Schottky diode
30VA High Quality Noise Shielded Transformer
New LPS/4 specs announced this week, now it appears the "poor man's" unit you are considering is only on the edge of compatibility in terms of constant current, and not within the new spec of 1500mA peak. And that's assuming the specs on the "poor man's" unit are accurate and represent real life as opposed to "test bench only" attainable:
Geek Linear Power Supply:
Based on this I would not recommend buying that particular poor man's unit, although it might still work fine given the standard Pulse's PSU (non-LPS) that comes with a base model Pulse might not be any beefier, although it is probably a SMPS and so inherently different.
