The EL2595 EtherCAT Terminal contains a constant current source for LEDs and is designed to control one or more LEDs connected in series. The user specifies the required set current, the integrated power supply unit then provides the required forward voltage, depending on the connected LEDs. For this purpose, the EL2595 has a step-up/step-down power supply unit, which generates the output voltage from the 24 V DC input voltage. The output voltage is also adjusted during operation in order to maintain the set current. The current can be switched quickly for short-term lighting, hence even extremely short flashes of light are possible. The pulse duration is adjustable from 1 µs to infinity, the flash time itself can be set through a timestamp via distributed clocks; an external trigger input is also available. Extensive real-time diagnostics, e.g. for input current/voltage and output current/voltage allow detailed monitoring of the LED light intensity. If a specifiable load corridor is exited, e.g., due to load errors, the EL2595 switches off to protect the load (resettable).

Special features:

• Suitable for simple lighting tasks and continuous LED operation
• Max. output current 300…700 mA
• Optional automatic operation in case of communication interruption
• Support of XFC technology timestamp
• Synchronized operation through distributed clocks XFC technology possible

Application recommendations:

• The EL2595 LED terminal of the 1st generation is often sufficient for simple lighting tasks.
• The EL2596 and EL2596-0010 are the significantly more powerful successors and are thus suitable for applications requiring high-precision control.
• The EL2564 is the right choice for simple continuous lighting applications with RGBW LEDs in voltage mode.
