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)
