UPS or Buffer Modules

[kckku]

Does anyone have any recommendations on UPS or buffer modules that can handle power flickers? We don't need a system that can back up for an extended length of time like an hour. The problem that we have is short flickers in quick succession.

One of our machine suppliers suggested an ABB DPA 60 system (40 kVA). There is some hesitation from management because the system is quite large and the cost is quite high. This is why I am wondering if anyone else have similar systems or recommendations.

Thanks.
