| Selection List |
remarks:
1. The standard function of GC-DB200 is to measure three-phase current, with standard protection, 1 relay output, 1 switch input, and no communication. Standard protection is described in the performance indicators.
2. If the above options are not specified, it means that the function is not required. For example, if only GC-DB200 is specified, it means that only the standard features of GC-DB200 are selected.
3. When selecting, indicate the voltage level, with 380V and 690V options available, and specify the voltage range of the power supply.
4. If the - A function option is selected, the protection function will add overvoltage protection and undervoltage protection.
5. GC-DB200-60-A-2DI-2DO-380, with standard functions, voltage protection, 2-channel switch input, 2-channel relay output, 60A through core transformer, line voltage connection of 380V.
