Speed controllers VENTS RS-1-0,5 | official VENTS website

Description

APPLICATION	MODIFICATIONS
Used in ventilation systems for switching on/off and speed control of single-phase fan motors with voltage control. Several fans can be controlled from the same unit in case the total consumption current does not exceed the permissible controller current value.	RS-1-0,5 – a speed controller without a mounting junction box. RS-1-0,5 N – a speed controller, completed with a surface mounting junction box. RS-1-0,5 V – a speed controller, completed with a flush mounting junction box. RS-1-0,5 NV – a speed controller, completed with surface and flush mounting junction boxes.
DESIGN AND CONTROL	PROTECTION
The casing is made of plastic. The controller is featured with high efficiency and control accuracy. Turn to maximum speed by rotating the control knob. Regulation starts from the minimum to the maximum voltage value. The maximum speed produces the smoothest rotation. The minimum speed value is set by a variable resistor located at the controller circuit board.	The input circuit of the speed controller is equipped with a fuse for overload protection. The controller is equipped with a transient filter.
MOUNTING
The controller is designed for indoor mounting into special surface mounting (MKN-3) or flush mounting (MKV-4) junction box (under separate order) or into standard round electric junction boxes.
