Introduction
1-channel LED constant current source
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 VDC input voltage. The output voltage is also adjusted during operation in order to maintain the setpoint 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 200 µs to endless. As with the EL2252, the flash time itself can be set by a distributed clock timestamp; however, an external trigger input is also available. Extensive real-time diagnosis functions for input current/voltage and output current/voltage enable detailed control of the LED light intensity. If a definable load corridor is left, e.g. due to a load error, the EL2595 switches off after a warning to protect the load. This can be reset.
