Automatic exchange regulator single / three-phase technical parameters and pricing

Technical parameters: Input voltage: 160V ~ 260V (lotus-type 3KVA less) 170V ~ 250V (compensation less 5KVA) Output voltage: 220V voltage accuracy (3KVA less with 110V output): ± 1 ~ 3% adjustable (factory of ± 2%) response rate: ≤1S (input voltage 10%) Frequency: ≥90% & (three phase) is a combination of three single-phase power supply, the use of grouping independent structure, reliable, easy to use, can effectively eliminating the three-phase power grid or load changes due to the imbalance caused by the device's impact on the technical parameters: Input voltage: 280V ~ 450V (lotus-type 10KVA or less) 300V ~ 430V (compensation above 15KVA) Output voltage: 380V steady Pressure Accuracy: ± 1 ~ 3% adjustable (factory set to ± 2%) response rate: ≤1S (input voltage 10%) Frequency: ≥90%
