English Electromotive actuator SQN70.454B20 for air dampers and control valves on oil and gas burners, low to medium output.
General information:
The SQN7...actuators are designed to drive gas and air dampers on oil and gas burners of low and medium heating capacity for load-dependent control of the fuel and combustion air volume:
- in conjunction with P-PI or PID controllers, e.g. RWF40...
- directly via the various automatic burner controls, e.g. LFL..., LME..., LMG..., LMO..., LOA...
- in conjunction with single-wire, 2-wire or 3-point controllers
Technical data:
Type: SQN70.454A20
Mains voltage: AC 230 V -15%/+10%
Mains frequency: 50...60 Hz ±6%
