can i use 1000va stabilizer for high thermocool of HTF -200L? Can it works

Yes

YES.
That freezer would most likely consume less than 200w during operation. But starting power when it's coming on can peak close to the 1,000w of the stabilizer. But since that usually happens in less than a second, the stabilizer can endure it.

But if you do experience low voltage in your area, this will put more burden on the stabilizer, because the freezer would spend more time starting up, and may start and stop more frequently than normal, or may have many failed starts. In this case, use 2,000va stabilizer or more.
