Description
The Weishaupt SQM48.497B9 servo drive, art. 651503, has an improved, vibration-resistant design, interchangeable with earlier versions. Provides movement of the air damper, gas valve and other similar devices with a rotary action. It is built into automatic control systems for the supply of the working medium of industrial gas and liquid fuel burners. It helps to obtain the optimal proportion of fuel and air and the efficient operation of the combustion unit. The operating parameters (direction of shaft rotation, end points, operating time) are set on the main control device.
Main characteristics and features:
power supply from the 2x12 V mains;
adjustment of the damper opening parameters in the range of 0 ... 90 °;
duration of movement at 90 ° - 30 sec.;
stepper motor with a torque of 20 Nm;
IP 54 dust and moisture protection level (requires appropriate Pg11 seals);
stable operation regardless of voltage or load changes;
power supply via CAN bus cable or transformer;
economical power consumption;
precise rotation of the damper to a specified angle, taking into account the settings and signals of the automation;
durable aluminum alloy housing with heat-resistant plastic casing;
easy setting of switching parameters;
feedback on the position of the air damper via the CAN bus;
permanent lubrication of the gear mechanism that does not require replacement;
placement in any position;
4 holes for secure fixation on the work surface;
operating temperature range: -20 ... + 60 ºС.
Configuration
The Weishaupt SQM48 servo drive is assembled in a shockproof housing that reliably protects the working unit from external influences. Spur gears with small circumferential clearance are made of wear-resistant plastic. The drive shaft is made of steel with a blackened finish. The front side of the gear is used as a mounting surface. The gear is constantly self-lubricated, does not require additional maintenance.
Advantages:
Precise opening of the air damper;
Low-voltage supply voltage;
Reliable design with a cast aluminum housing;
Feedback via the CAN system bus;
Economical power consumption;
Self-lubricating gear;
Wide range of operating temperatures;
Easy installation and parameter setting.
Weishaupt SQM48 servo drives can be equipped with additional accessories upon request: shielded cable, special RAST3.5 terminals, adapter for gas valves, etc.
