To increase the current, use the DC1-48 90/0 PAR and connect two outputs from your power supply to power one unit. The current from one output will be added to the other. Example: the total current from connecting two outputs with 800mA each will be 1600 mA. 2.1 mm plugs. 48 cm cable.
IMPORTANT! Requires a power supply with isolated, floating outputs.
