- Dual High Power LED Output Channels - Highly stable, low Noise Output - Single Power Supply Input for ease of installationTrigger via opto-isolated digital inputs or RS232 command - Trigger Input Level:5 V - 30 V - Programmable post Trigger Delay 10 µs - 999.9 ms - DIN rail mounting option available The new Dual Intelligent Constant Current LED Controller (ILC2008) from IMSTec GmbH is a LED controller especially designed for applications that require low noise on the optical output. The latter requires a constant current source which also has low noise properties. Any current change reflects in the light output since LEDs have a linear light-current dependency over a huge operational range. Many standard lightning controllers utilize efficient pulse width modulation (PWM) to tune the average current to the targeted value. This technique is very efficient regarding both cost and power but is limited to applications which integrate over many PWM cycles and therefore average out the high frequency components (like the human eye). When using faster imaging sensors appropriate parameters for PWM frequency and exposure times have to be chosen or synchronization mechanisms need to be established which may not be possible in all applications. The ILC2008 controller overcomes these difficulties by an alternative current source topology.
