It is Universal Robots recommendation that if one insists of using an AC/DC to DC/DC setup, to use our own LCM1500W-T 48V PSU, P/N: 177526. This is the same PSU that is used for UR5e/UR10e/UR16e.
If one chooses not to use the recommended PSU, it should be noted that Universal Robots takes no responsibility.
Furthermore, one should not run a program that requires more power than a certain PSU can deliver. If unsure of how much power is needed, modify the configuration file. This is done in a terminal by typing nano .urcontrol/urcontrol.conf. In the subsection [Hardware] change to power_supply = 750 when a 36V or 48V battery supply is used. When a 24V battery supply is used, change to power_supply = 500
In case an UR3e is used, then power_supply = 600 when a 36V or above battery supply is used.
