Vadsbo LD220 Low Power Dimmer
Installation Manual
Product Overview
The Vadsbo LD220 is a low power dimmer designed for efficient lighting control. It starts operation at 1VA and is controlled by one or more resilient 1-pole push buttons (toggle switches). This design allows for dimming from an unlimited number of locations within a room.
The LD220 is suitable for a wide range of light sources including dimmable LED lamps and drivers, low energy lamps, 230V halogen lamps, low voltage halogen lamps, incandescent lamps, and electronic transformers utilizing trailing edge control.
Key features include a soft start, overheating protection, and a memory function that retains the last set light level upon power cycling, even after a power interruption.
Key Functions
- On/Off: A short press turns the dimmer on or off. It will resume at the last used light level (memory function).
- Dimming: Hold the push button to increase or decrease the light level until the desired brightness is achieved.
- Minimum Dimmer Level Adjustment: The minimum dimming level can be adjusted using a screwdriver. Turn the rotary potentiometer with the screwdriver to set the level, then test by dimming up and down. Note that low energy lamps and LEDs may require different minimum settings due to their lower power consumption.
