LED Dimmer LED-02E-500-STR

LED Dimmer with 2 outputs for powerless dimmable LEDs with a constant voltage control, loadable with 500mA each. Dimming 0-100% high resolution, monochrome coloured or circadian/HCL (Human Centric Lighting warm white/cold white).

Quick Facts

  • 2 dimming channels for LEDs 18-50V DC, max. 500mA
  • dimming 0-100%
  • 1-10V potentiometer
  • pushbuttons

The 2-channel LED Dimmer was developed for powerless dimmable LEDs and LED lamps. Here 2 PM outputs with a respective load capacity of up to 500mA are available. The control functions focus on stand-alone applications. 6 different operating modes can be set.

The operating modes are subdivided into:

  1. Separate control of both channels via 1-10V potentiometer or pushbuttons.
  2. Coupled control of both channels for circadian (colour temperature) light control. In this application, warm white LEDs (e.g. 2700K) are connected to the first channel and cold white LEDs (e.g. 6000K) to the second channel. Here you can control the brightness from 0-100% and the colour temperature ratio (2700K to 6000K).

An external power supply unit is also required for operation. This must be dimensioned according to the type of LEDs used.

Electrical Data

Operating voltage 18 V DC to 50 V DC
Input current (dimming position 100%) Imax for short circuit at PWM-Out -> I = 2 A (Imax)
Output short-circuit-proof
Standby input current (dimming position 0%) at Ub = 24V -> I = 13mA -> (Standby power = 320mW)
at Ub = 48V -> I = 8mA -> (Standby power = 384mW)
Output current load max. 500mA per channel
Output voltage corresponds to the operating voltage - 1V - voltage drop of the line. The LEDs must be suitable for the corresponding voltage!

Use to control 2 independent single channels

Connection power supply unit and LED load for single dimming 2 channels


Mode 1: Dimming and switching with 1-10V potentiometer

 

Here the brightness of the channel is controlled with the potentiometers. If the potentiometer is turned to the left, it is switched off.


Mode 2: Dimming and switching with 1-10V potentiometers and pushbuttons

 

In this mode the brightness of the channels can be adjusted with a 1-10V potentiometer each. Switching on/off is realized by one pushbutton each. If several control points in the room are required, additional pushbuttons can be connected in parallel. 


Mode 3: Dimming and switching with pushbuttons (single-button dimmer)

 

Pressing a button briefly (<0.5s) switches the light source of the corresponding channel on or off. The lamps are dimmed by long pressing of the respective button (>0.5s). Each interruption of the dimming process (release the button) switches the dimming direction (UP ↔ DOWN).

The dimmers can be operated with 2 different button modes. The modes can be individually programmed by the customer for each channel:

Button mode 1: Switch on with 100% (factory setting)

  • The dimmer always switches on with 100% dimming level. 
  • Setting of button mode 1:
    1. Turn on the dimmer
    2. Dimming to max. value and keep the dimming button pressed (approx. 30s) until the light source is blinking 6 times.   


Button mode 2: Switching on with last switch-off value (optionally adjustable)

  • The dimmer always switches on with the last switch-off value.
  • Setting of button mode 2:
    1. Turn on the dimmer
    2. Dimming to min. value and keep the dimming button pressed (approx. 30s) until the light source is blinking 3 times.

Use for controlling circadian lighting

Mode 4: Circadian lighting - dimming and switching with 1-10V potentiometers

 

The first potentiometer is used to adjust the brightness of the lamps. When dimming, the light colour remains constant. The second potentiometer controls the light colour, when changing the brightness remains constant.


Mode 5: Circadian lighting - dimming with E-potentiometers and switching with pushbuttons

 

In this mode, the brightness or colour of the circadian lighting can be adjusted with an E-potentiometer each. Switching on/off is realized by a pushbutton.

If several control points in the room are required, additional pushbuttons can be connected in parallel.


Mode 6: Circadian lighting - dimming and switching with pushbuttons (single-button dimmer)

 

Pressing a button briefly (<0.5s) switches the lighting on or off. To dim the brightness or the colour of the lighting, press and hold the button (>0.5s). Each interruption of a dimming process (release the button) switches the dimming direction (UP ↔ DOWN). The dimmers for brightness and colour can be operated with 2 different button modes. The button modes are individually programmable for brightness and colour by the customer:

Settings button modes for brightness 

Button mode 1 (brightness): Switch on with 100% (factory setting):

  • The dimmer always switches on with 100% dimming level.
  • Setting of button mode 1:
  1. Turn on the dimmer
  2. Dimming to max. value and keep the dimming button pressed (approx. 30s) until the light source flashes 6 times.

Button mode 2 (brightness): Switch on with last switch-off value (optionally adjustable):

  • The dimmer always switches on with the last switch-off value.
  • Setting of button mode 2:
  1. Turn on the dimmer
  2. Dimming to min. value and keep the dimming button pressed (approx. 30s) until the light source flashes 3 times.


Settings button modes for colour

Button mode 1 (colour): Switch on with mixed colour 50/50 (factory setting):

  • The dimmer always switches on with mixed colour (50% warm and 50% cold).
  • Setting of button mode 1:
  1. Turn on the dimmer
  2. Dim (colour) to "cold" and keep the dimmer button pressed (approx. 30s) until the light source switches 6 times between "warm" and "cold".

Button mode 2 (colour): Switch on with the colour of the last switch-off process (optionally adjustable):

  • The dimmer always switches on with the colour set at the last switch-off.
  • Setting of button mode 2:
  1. Turn on the dimmer
  2. Dimming (colour) to "warm" and keep the dimmer button pressed (approx. 30s) until the light source switches between "warm" and "cold" 3 times.
