Belimo LH24A300 - linear actuator for dampers

Belimo LH24A300 – linear actuator

The actuator is designed to control dampers and gates in stationary heating, ventilation and air conditioning systems. According to the technical data sheet, it supports air dampers with an area of up to approx. 1 m².

Key features and specifications

• Actuator force: 150 N.
• Rated voltage: AC/DC 24 V; frequency: 50/60 Hz.
• Control: Close/Open, 3-point.
• Stroke: 300 mm; max. 300 mm, adjustable in 20 mm increments using Z-AS2 mechanical end stops.
• Motor running time: 150 s / 100 mm.
• Power consumption: 1.5 W while moving, 0.5 W in the resting position; sizing value for cables: 3 VA.
• Power and control connection: 1 m cable, 3x 0.75 mm².
• Direction of movement selected with switch 0 (extended) / 1 (retracted).
