Modular device for DIN-EN 60715 TH35 rail mounting. 2 modules = 36mm wide, 58mm deep.
Universal dimming actuator for R, L and C loads up to 800 watts, depending on ventilation
conditions. Automatic detection of load R+L or R+C. ESL and LED is manually settable.
Dimmable energy saving lamps ESL up to 100 watts and dimmable 230V LED lamps up to
100 watts.
Up to 3400W with capacity enhancers LUD12-230V
(for description see next page) at
terminals X1 and X2.
Zero passage switching with soft ON and soft OFF to protect lamps.
Switching voltage 230V. No minimum load required.
The 12V DC supply voltage of the complete RS485 bus is mainly powered at 6W, 12W or
24W by a switch mode power supply unit SNT12-12V DC that is only 1 or 2 pitch units wide.
The power consumption of the 12V DC power supply is only 0.05W.
The brightness level is stored on switch-off (memory).
In case of a power failure the switch position and the brightness stage are stored and may be
switched on when the power supply is restored.
Automatic electronic overload protection and overtemperature switch-off.
Connection to the Eltako RS485 Bus, terminals RSA and RSB.
Up to a total of 128 actuators can be added in this way.
The top rotary switch LA/LRN
is first required for teach-in and in operation, it defines what
load type the dimming curve should be set to.
Position R, L, C
is the setting for all load types except for ESL and LED. In particular for 230V
glow and halogen lamps. The load type, inductive or capacitive, is detected automatically.
The settings +ESL and -ESL
consider the special conditions regarding dimmable energy saving
lamps: The starting operation is optimized and adapted to the dimming curve. In these settings
the special switching operation for children's rooms is not possible and no wound (inductive)
transformer must be dimmed. In position
-ESL Memory is switched off. This can be of advantage for
energy saving lamps because cold energy saving lamps require a higher minimum brightness as it
will possibly be stored in Memory for warmer energy saving lamps.
The position LEDs
take account of special conditions with dimmable 230V LED lamps:
A number of different dimming curves are available. An updated list with dimming curve
assignment for commercially available dimmable 230V LED lamps is ready for downloading
at
www.eltako.com/dimming_curve/LED_gb.pdf. In these settings no wound (inductive)
transformer must be dimmed.
The minimum brightness (fully dimmed down) or maximum brightness (fully dimmed up)
is adjustable
with the top % rotary switch. In the setting LRN up to 30 pushbuttons can be
assigned, of which one or more central pushbuttons.
The dimming speed is adjustable using the
bottom dimming speed rotary switch. At the same
time, the soft ON and soft OFF periods are changed.
The pushbuttons can be taught-in either as direction switches or universal switches:
When installed as a direction switch,
one side is then 'switch on and dim up' and the other
side is 'switch off and dim down'. A double-click on the switch-on side activates automatic
dim-up to full brightness at dim speed. A double click on the switch-off side activates the
snooze function. The children's room function is implemented on the switch-on side.
As a universal switch
, change the direction by briefly releasing the pushbutton. With switching
operation for children's rooms and snooze function.
Functions
switching for light alarm clocks, switching operation for children's rooms, snooze
function, light scenes on PC
and light scenes by wireless pushbuttons same as FUD12NPN.
The LED
below the upper function rotary switch performs during the teach-in process according
to the operation manual. It shows control commands by short flickering during operation.
