Having finally been able to check...
The E3 power supply is model EM3002A and provides 33.5V, 200mA. The E2 power supply is model EM2001A and provides 28V, 280mA.
I list the model numbers because they're otherwise identical, even to the connector. Obviously by the fact that your E3 is running on the E2 supply there's a certain amount of safety margin, but still, you may want to be careful. (I certainly wouldn't want to try it the other way round.)
Thank you! The seller sent a separate power supply premise to reduce the total cost of forwarding. I expect it the other day. However, in general it works with the power supply of E2.
