DESCRIPTION


With this module it is possible to dim lamps operating on mains voltage. Also suitable for dimming low voltage
lamps in combination with a wire-wound iron core transformer.

PROPERTIES

Use:

 Required mains voltage: 220...240V/50Hz

 Suitable to control incandescence or halogen lamps on mains voltage

 Suitable to control low voltage halogen lamps in combination with a dimmable wire-wound iron core

transformer

 Suitable for some types of dimmable LED lamps on mains voltage

Output:

 Maximum load: 400W @ 230V/50Hz

 Leading edge phase control

 Slowly switching on and off (ca. 1.5s) will prolong the life span of the lamp

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

 Power grid distortion (EMI) conform EN55015


Protection:

 Built-in non-resettable: 4A slow

 Verification of too inductive loads (holding current triac). This protection can be disabled for some types of

lamps e.g. dimmable lamps

 Thermal

protection:

o When temperature reaches 80°C, light output is reduced to 25% of the desired value
o When temperature reaches 90°C, the lamp is switched off
o Thermal protection is switched off when temperature drops below 60°C
o Tolerance on thermal protection: ±4°C


LED indications:

 Status of the dimmer:

o Continuous on: desired dimming value reached
o Slow flash: timer running
o Fast flash: dimming value changing
o Two short flashes: communication error detected
o Three short flashes: not possible to dim load with this dimmer
o Four short flashes: temperature alarm (light output reset to 25% of desired value)
o Five short flashes: thermal protection (lamp is switched off)

 Presence of input voltage

 Sending and receiving Velbus data

 Report status to control modules


Module power:

 Required input voltage: 12...18Vdc

 Consumption in stand-by: 28mA@18Vdc

 Maximum consumption: 30mA@18Vdc


Dimensions:

 Standard DIN-rail housing: 2 modules wide

 Length x width x height: 90 x 36 x 58mm


Configuration:

 Only configurable via Velbus PC interface (VMB1USB, VMB1RS or VMBRSUSB) and the VelbusLink

software

 Software addressing (up to 250 possible addresses)

 Storage capacity for 37 different pushbuttons and their function

 Multiple functions and time settings can be set via software

 Learned pushbuttons are maintained during power outage
