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
