Siemens SQN72.6C4A20BT actuator

Air damper control for Baltur burners – Siemens SQN72.6A4A20BT servo drive. Siemens SQN72.6A4A20BT is a reversing servo drive for the air damper, designed specifically for Baltur burner devices. It provides precise regulation of the air-to-fuel ratio in the combustion mixture – a key factor for high efficiency, economy, and safe burner operation at any power level. Application: The main purpose is to change the position of the air damper for optimal air supply when creating the combustion mixture, which increases combustion efficiency and improves the efficiency of the heating installation. The servo drive is used in automatic fuel and gas supply systems for medium and low power Baltur burners. Depending on the load, the servo drive operates under the control of a burner control or together with single-wire, two-wire, or three-position control. Main characteristics: Power supply: 220 V, 50/60 Hz. Torque: 2.5 Nm. Power consumption: 6 VA. Opening time for 90°: 30 seconds. Operating temperature range: -20…+60 °C. Maintenance-free, as the reliable design of the servo drive includes a maintenance-free gearbox with disconnection capability – secondary engagement occurs automatically. The package includes easily adjustable limit and auxiliary switches, internal position indication. The gear transmission is treated with long-lasting lubricant, eliminating the need for mechanical maintenance. The housing is made of impact-resistant, heat-resistant material; dust and moisture do not penetrate inside the device.
