5 Configuration
5.2 Configuration example
Requirements Controller load voltage 400V
Load voltage 230V (star connection)
3 heating elements (3 elements with 1kW each connected in parallel)
Load current: 9000W/(3x230V)= 13A
Temperature coefficient TC = 1
Operating mode: Phase-angle control
Cascade control: U
2
Base load: 0%; maximum output level 100%
Default set point value via input signal of 0 ... 20mA.
These requirements are sufficient for the following power controllers:
Device type 70.9062/8-01-020-100
-400-252
Attention:
- make sure that the rotating
electric field is right handed!
- only possible in burst firing mode
