For the moment, I have set the current limit low (1A) so that the power limit will not be exceeded; but now the 2510 does not go anywhere near the voltage limit (maxes out around 3.5V), and hence supplies only about a 1/3 of the max power of the TEC. This in itself isn't a show-stopping problem, but the fact that it limits the usable temperature range is a show-stopper. This means I can only raise the temperature by < 40 C above ambient even though the reported delta-T of the TEC is 90 C. (This is with no other thermal load to the system.) A worse problem occurs if I max out the current limit and instead reduce the voltage limit to prevent an overload in power.
Unfortunately I cannot see where to set the power limit, and have not found this in the manual, which would be a better way than reducing either the voltage or current limits. The datasheet explicitly states that the power limit *can* be set, but if you can tell me how, it would be most helpful. Cheers.

is operating in it will reach one limit before it hits the other and will be prevented from
going any further. There is no direct "power limit" setting - just enter what the manufacturer
recommends for the voltage and current limits and it should work just fine.
The flaw in just multiplying the max voltage by the max current is that the Peltier will never
operate in that "corner" of the acceptable voltage and current limits at the same time.
