The EL2564-0010 digital output terminal controls LEDs with integrated series resistor via an adjustable (ground switching) PWM signal. Common anode RGBW LEDs can be controlled with the four channels. But also the operation with four LEDs of the same color is possible with the terminal. The terminal has a flexible input voltage of 5…48 V DC. The output voltage corresponds to the input voltage. For the operation of multicolor LEDs the color portion per channel is adjustable. Thus any color mix can be realized. In addition to the color mixing per channel, the adjustment of the total brightness over all channels is also possible. Another parameter that can be adjusted is the frequency. By setting the frequency in a range of 1…16,000 Hz, stroboscopic effects can be avoided. Furthermore, visible flashes can be realized by the low frequencies.

Special features:

• flexible input voltage 5…48 V DC
• adjustable color component per channel with multicolor LEDs (adjustment of the duty cycle)
• adjustable total brightness across all channels
• adjustable frequency 1…16.000 Hz, for the avoidance of stroboscopic effects and the realization of visible flashes at low frequencies

Recommended uses:

• the EL2564-00x0 is the right choice for simple continuous light applications with RGBW LEDs in voltage mode
• the 1st generation EL2595 LED terminal is often sufficient for simple lighting tasks
• the EL2596 and EL2596-0010 are its successors with a greatly increased performance and are thus suitable for applications where there is a demand for high-precision control
