Protection for amp?

[ShaQBlogs]

Kindly excuse, although this is not an DIY amp, I have a question regarding amps.

I just purchased a Crown XLS 1500 for DIY subs that I am constricting. I live in a region of power instability. Voltage is 220V region, but voltage varies wildly from 150V to 260V. At times it even goes over board and at times way under. Rapid variation in voltage is common.

Is it safe to connect the same to wall outlet directly?

anyone???

The specification says it can deal with 220 / 240VAC, 10% tolerance, so this gives 264VAC as the upper limit.

I am not so sure about the specific model, but most PSUs can deal with even higher AC voltage without damage.
If the PSU does not contain a PFC boost converter, a line voltage sag can reduce available output power or even lead to temporary shut down, but to a well designed PSU it should not do any damage.

thanks for the reply
Would connecting this help? I was intending to connect this to protect from wild swings. But how about surges, spikes, brownouts...would it help?

I was told another problem could occur when a power off is immediately followed by power back on resulting in a current surge??

Also the crown amps from what I have heard are built really well

This device protects from surges, brownouts, overvoltages. I think it could help although it would not come for cheap. I once had my computer system connected to such a device from APC. It was not exactly the same device, but a "UPS", that could also regulate the ac supply.
