Sometimes it takes a while to root around and figure out where things are.
We were looking at comparing the two 1500VA rack mount UPS offerings from APC and initially found it difficult to find the comparison button:
It is the third item down in the left column. :)
The number we are looking for is the Surge Let-Through. Both should be the same or very similar but for some reason finding the number for the SURTA1500RMXL2U has been more than difficult.
So, we called: 1-800-800-4272 and chose the Support Option for Smart-UPS. Our result:
- 0.3% Surge Let-Through (330 Volt).
- Wikipedia: An explanation of Clamping voltage
They are virtually identical.
