Information About LKS210-10
The LKS210-10 is part of Honeywell’s LKS210 series of modulating actuators, primarily used in oil or diesel burner systems and industrial combustion setups. Typical specification notes indicate operation at 200-240 V AC, 50/60 Hz, with a duty cycle of 70% ED. It features a synthetic, self-extinguishing housing, worm gear drive with self-locking function (for secure flap positioning when power is off), and drive output shaft compatible with standard flame-train or damper linkages. This actuator is frequently found in retrofit installations for burner manufacturers such as Riello and other European burner OEMs.
Key Features:
- 200-240 V AC Operation (50/60 Hz): Suits standard burner control voltage ranges.
- 90° Stroke Angle in ~5 Seconds: Rapid actuator speed for improved system response.
- Self-Locking Worm Gear: Maintains flap position after power is removed, enhancing safety and reliability.
- High Torque Output: Typical torque around 1.5 Nm for damper/flap control in combustion systems.
- Synthetic, Self-Extinguishing Housing: Designed for safety in industrial heat/ combustion environments.
- Direct Shaft Coupling: Square socket (≈ 8×8 mm) or Ø10 mm shaft depth 25 mm for direct linkage connection.
- IP44 Protection Rating (depending on variant): Suitable for indoor burner room or industrial environment use.
- Maintenance-Free Design: Long service life with minimal upkeep required.
- Wide Ambient Temperature Range: Typical range –10 °C to +60 °C (operational environment).
- European OEM Compatibility: Frequently used as original or replacement actuator in burner assemblies and damper systems.
The LKS210-10 delivers the reliability and precision required for modulating burner or damper control in industrial and commercial combustion systems.
