I calculated what i would need for my modest setup of 8 modules and thought i would be okay with one of these but i forgot to add up both power rail's consumption this unit has a maximum of 200mA and got quite hot with erratic performance. I cant imaging a real use for the supply maybe 4 modules could be powered by it. Shame Doepfer are such a great company providing us with affordable modules. All the other power supplies come in very expensive cases, i built my own to keep the prices down. Wish they did a supply of around 1.5 Amps.
