5 Configuration
5.2 Configuration example
Requirements
Load voltage on the power controller 400 V
Load voltage 230 V (for wye connection)
3 heating elements (each with 1 kW connected in parallel)
Load current: 9000 W / (3 x 230 V) = 13 A
Temperature coefficient TC = 1
Subordinate control loop: U
2
Base load: 0 %; maximum output level 100 %
Default setpoint value via standard signal of 0 to 20 mA
These requirements are sufficient for the following power controllers:
Device type
709062/X-01-020-100-400-252
Attention:
- Make sure that the rotating
electric field is right handed!
- Only possible in burst firing mode
