VMB1LED PWM LED strip dimmer Manual– edition 1_rev.2

DESCRIPTION

LED illumination is getting more popular. By dimming the output of the LED strips (12V or 24V series) an

attractive atmosphere can be created. A dimmer module is placed between the external LED power supply and

the LED strip.

The use of Pulse Width Modulation (PWM) greatly reduces heat development inside the dimmer module

compared to linear regulators.

CHARACTERISTICS

Dimmer:

• Suitable for dimming 12 or 24V LED strips or low voltage lamps.

• Can also be used to regulate the speed of DC motors (10 to 30V)

• Not suitable for LED lamps with built-in driving electronics

• Maximum consumption: 5A (60W@12V or 150W@30V)

• High efficiency by using PWM

• PWM frequency: ca. 100Hz

• Gradually switching on and off (ca. 1.5s)

• Dimming from 0 to 100% in ca. 4 seconds

• Short-circuit proof

• Thermal protected

• Protected against wrongly connected power supply by a 20A fuse

• Required external power supply: 10 to 30Vdc / 5A

• Power supply dimmer galvanically separated from the Velbus power supply

Operating modes (selectable through the ‘MODE’ rotary switch):

• instant control

• Start/stop timer

• staircase lighting timer

• dimmer

• dimmer with memory

• multiple positions dimmer

• gradually-on dimmer

• gradually-off dimmer

• gradually on/off dimmer

Time settings (adjustable through the ‘TIME’ rotary switch):

• switch-off time (or dimming speed when gradually on/off dimming

• 16 possible time settings: instant - 5s - 10s - 15s - 30s - 1min - 2 min - 5min - 10min - 15min - 30min - 1u - 2u

- 5u - 1dag – on/off

Control:

• by placing multiple pushbuttons in parallel

• de-chattering of the pushbutton input: 65ms

• local control on the module

• through Velbus instructions or through pushbuttons connected to the Velbus system

• Operating functions:

o by pushbuttons that switch the LEDs on (full brightness)

o by pushbuttons that switch off the LEDs

o by pushbuttons that switch the LEDs on (full brightness) or off

o by pushbuttons that activate the selected mode on the module

o by pushbuttons that make the LEDs shine more bright

o by pushbuttons that make the LEDs shine less bright

o by pushbuttons that create a atmosphere

o by slider controls that turn on the LEDs with the desired brightness
