Hi - I was looking at the specs of my UPS's and I was underwhelmed. I have several APC Back-UPS-ES550vA units and recently noticed that the surge protection is limited to 340 joules. The surge rating seems extremely low when comparing other dedicated surge protection strips.

Does anyone know if UPS devices offer protection using other methodologies for:
(A) the UPS protected outlets, and
(B) the surge-only protected outlets?

Is surge rating a good benchmark to evaluate UPS devices?
