Does anybody know how to change the output voltage and limit the output current in the Delta Electronics ESR-48/40AE charger? The following web pages http://www.sanmpower.com/display.php?id=80 and the next one http://www.sanmpower.com/display.php?id=78 have pinouts for two other Delta chargers that seem to match my charger. I'm linking these images directly here:
Delta ESR-48V/56AC 54V(54V~59V) 50A
Delta ESR-48/30G C 54V(43V~58V) 32.22A
I have attached pictures of my charger and a two page fact sheet PDF.
