THE ALL-ROUND PARTNER FOR HOME AND BUILDING AUTOMATION WITH KNX

KNX news

The German manufacturer Enertex presents its unique dimmer for LED strips KNX LED Dimmsequenzer 20A/5x with unique features on the market.

 

This novelty is a great advantage! Now, with LED strips that include RGB+CCT (Correlated Color Temperature) technology we have the opportunity to combine the RGB part with the cool white and warm white control part, automatically generating softer colors and a wider white range, among many other functions.

 

Until now, for RGBW lighting, a dedicated RGB color adjustment component independent of the color temperature or white component was required, where the adjustment had to be performed on each of them individually, i.e. in 2 steps. Now, the RGB+CCT technology allows to manage colors and white light in an improved way compared to the usual way.

Enertex has been the first to introduce this mode to the market in the current generation of KNX devices and calls it "RGB extended" and "TW extended".

For the examples described below, RGB+CCT LED strips are considered, which have 3 emitting diodes: One diode with 3 colors for RGB and another 2 white light diodes to achieve dimming within the range of approximately 2,700K to 6,000K.

EXAMPLE OF "EXTENDED RGB":

- Requirement: To achieve a Smoothed Blue tone, taking into account the white tones:

- Normal solution: In normal RGB application or when automatic blending is disabled, to achieve this effect, you have to reduce the saturation, i.e. it is achieved by setting the Blue color to 100% and blending the R and G channels by 50% each.

- Solution with Enertex: Allows the two white channels to be mixed automatically when the saturation of a color value is lowered. This results in a "nicer" white tone than the white tone mixed by the RGBW colors, achieving softer colors, avoiding adjusting the saturation.

The calculation of the color values and the mixing of the white channel is done internally in the device and does not have to be parameterized by the user. Only the desired color temperature of the white LEDs has to be specified.

EXAMPLE OF "EXTENDED TW":

- Requirement: Extend the white range at the lower and upper end of those allowed by the LED strip whites (2,700K to 6,000K):

- Solution with Enertex: The "Extended-TW" application makes it possible to extend the color temperature range of the adjustable white channel by automatically mixing the R, G and B color channels in the same channel, in addition to the temperature values of the two white channels. The user does not have to perform any complex calculations or tests with each individual luminaire. Only the light temperature of the white LEDs has to be specified. The Enertex algorithm automatically determines the optimum control.

Parameterization:

- Warm white color temperature: 2,700 K

- Cool white color temperature: 6,000 K

- Minimum value: 1,000 K

- Maximum value: 10,000 K

 

With TW-Extended, by mixing the three RGB color channels, the warm white range is extended down to 1,000 K and the cool white range is extended up to 10,000 K.

So if you are looking for a LED strip for environments where there is indecision about which LED strip to install (RGB, white temperature control, etc..) or you need a control with automatic white balance or HCL (Human Centric Light), then the combination of RGB+CCT LED strips together with the Enertex dimmer is just what you need.

Among many other features, it can control up to 5 RGB+CCT channels and up to 20 A in total* and with a maximum cable length of 50 m* between the dimmer and the lamp (*see configuration in data sheet).

It also supports scenes, sequences, time and day controlled color temperature control (HCL) as well as KNX Data Secure.

The channel assignment in the ETS can be freely configured from all of the following options:

- 5x independent channels (c.i)

- 1x RGB+CCT

- 1x RGBW + 1x c.i.

- 1x RGB + 2x c.i.

- 1x RGB + 1x Tunable White (TW)

- 2x TW + 1x i.c.

- 1x TW + 3x c.i.

 

OUTSTANDING FEATURES:

- Five channels, pulse-modulated, max. 20 A total.

- Dimming power up to 480 W

- Variable input and output voltage from 5 to 48 V.

- Also suitable for lamps with high inrush currents (up to 100 A).

- Integrated protection against overvoltage and undervoltage, overcurrent (selective), overtemperature, polarity inversion

- Additional protection functions for power supply and lighting

- Commissioning functions via integrated display and buttons

- Free configuration of the channels

- Accessible in RGB or HSV color space

- Four dimming curves with soft dimming as well as PWM frequencies between 200 and 1200 Hz for optimum dimming results

- RGBCCT - RGBW: extended white balance or extension of tunable white color temperature space by adding R/G/B

- Automatic color temperature mimicking of incandescent lamps (Dim2Warm)

- Time-of-day dimming and day-dependent white control (Human Centric Lighting / HCL)

- Staircase lighting function

- More than 20 predefined sequences and up to 5 freely configurable sequences in RGB or TW operating mode

- Dimming and sequencing, scenes, bit scenes and blocking functions

- Measurement of voltage, current, power, temperature and telegram rate per channel

- Channel-dependent energy and cost meters

- Control of an external KNX switch actuator to switch off the power supply to the LEDs

- Easy installation: no external fuses or distribution terminals required, approved for cable lengths of up to 50 m

- Intelligent generation of pulse patterns to match the load of the power supply (increases the lifetime of the LED power supply)

- Optional encrypted communication with the KNX Data Secure protocol

- Available in two different formats:

        Ceiling version - Ref. 1174-DK

         DIN rail mounting version - Ref. 1174-REG

On May 26, 2020, the Glass Push Button II received the German Innovation Award 2020
Awarded "Winner" in the category "Business Excellence for Consumers - Smart Living".

Among its main characteristics we can highlight:

- Innovative group control
- The new multi-tap function
- Patch function
- RGBW status LED
- Integrated temperature sensor


The innovative advantage of Glass Push Button II lies in the combination of simple and sophisticated
It can be used as a "normal" button for lights and blinds but also has other functions such as group control, here the blind is activated by pressing a short / long normal button or individual movement, all blinds in a room are they move with a longer press.

With the German Innovation Award, the German Design Council established an award that makes innovation visible and recognizes the products and solutions that shape the future.

MDT and its development team thank you for the German Innovation Award 2020.
