Enertex® KNX LED Dimmsequenzer 20A/5x REG
The Enertex® KNX LED Dimmsequenzer 20A/5x is a pulse width modulating dimmer for 5 - 48 V LED modules. Per channel the dimmer can dim up to 20 A LED current and in total 480 W power maximum. The dimmer is suitable for any LED lighting device that are suitable for DC constant voltage. Since the overcurrent switch-off of the Dimmsequenzer has been designed to be very robust against false triggering at high inrush currents, it is also particularly suitable for lamps that have very high inrush currents. LV halogen lamps can therefore also be operated, as long as they are suitable for PWM dimming. We recommend the Enertex® LED PowerSupply series to supply the lamps. The dimmer operates with intelligent pulse pattern generation, whereby the switch-on pulses are distributed as evenly as possible over the five channels. This extends the life of the power supply and allows a smaller dimensioning of the power supply.
External distribution terminals are not required, as the device provides one plus and one minus terminal for each lighting channel and also for the LED power supply. No additional fuse is required in the DC circuit. The flush mount variant (variant DK) with double furniture marking is suitable for installation in furniture or ceilings, rail mounted variant (variant REG) for installation in the control cabinet. The permissible cable length between the dimmer and the lamp is up to 50m.
With the help of the display and the push buttons the installation of the complete lighting can be tested and put into operation without ETS software. For this purpose, a separate function for 1-button commissioning is provided. This starts a commissioning routine which measures the voltages and currents of all channels under full load. The correct dimensioning of lamps, power supply and cabling including the actual voltage at the lamp is determined via the display. The different dimming curves, PWM frequencies and dimming speeds for the connected lamps can also be tested via the menu on the display. The choice of four predefined dimming curves in conjunction with a dimming frequency between 211 Hz and 1200 Hz means that a suitable configuration for smooth and flicker-free dimming can be found for almost all lamp types.
With the help of numerous integrated protective functions, the device safely switches off the current in the event of an installation error. The protective functions here include reverse polarity protection, overvoltage and undervoltage protection, overtemperature protection and overcurrent protection, which acts selectively. In the event of a short circuit, only the affected channel is shut down. Once a fault condition is cleared, then the dimmer automatically restarts. Overloads on the lamp or LED power supply are indicated on the bus and optionally switched off. For this purpose, key parameters for continuous load and overload capacity must be parameterized. During operation, the device measures the actual currents and powers in each channel, the DC input voltage, the device temperature and the telegram rate. These values are both shown on the display and made available via communication objects on the bus. To record the power costs for the lighting, the device provides energy and cost counters for each channel by means of communication objects.
The independent channels can be parameterized in the application in any combination of cool white / warm white, as color channels or as individual channels. Current RGBCCT lighting stripes (red, green, blue, cool white, warm white) are also optimally supported. These lamps are perfectly staged with an automatic white balance (RGB-Extended) developed by Enertex or with the extended Tunable White color temperatures, which are generated by automatic admixture of R/G/B (TW-Extended).
The colors can be controlled either via the primary colors red, green and blue (color mode RGB) or via hue, saturation and brightness (color mode HSV). The dimmer supports 8-, as well as 1-bit scenes and also enables the locking of individual channels / channel groups by means of communication objects. Five sequences, i.e. sequences of color or color temperature controls in the range from seconds to hours with smooth color changes, can either be defined by the user or assigned to over 20 predefined color sequences. Different switch-on behaviors for day and night are supported as well as time-controlled dimming of channels / channel groups. The latter enables, among other things, time-of-day-dependent white light control (Human Centric Lighting / HCL) in Tunable White mode. The setpoints can be specified either as absolute times or relative to sunrise or sunset (astro function).
The bus communication can optionally be encrypted by means of KNX Data Secure.
