GE Series LED Light Source Controller
The POMEAS GE Series LED Light Source Controller is designed for reliable illumination control in industrial machine vision systems. It supports both front-panel operation and RS232 serial communication, making it suitable for standalone adjustment as well as integration into automated inspection equipment.
Each channel can be adjusted independently, allowing the illumination intensity of multiple machine vision lights to be controlled precisely according to different inspection requirements.
Flexible Multi-Channel Light Control
The GE Series combines digital brightness adjustment, independent channel control and industrial communication capabilities to provide flexible lighting control for machine vision applications.
![Multi-channel machine vision LED light controller product highlights]()
256-Step Digital Dimming Brightness can be digitally adjusted from 0 to 255 for repeatable illumination settings.
Independent Channel Adjustment Each lighting channel can be adjusted independently to match different inspection areas or lighting configurations.
Front Panel or Remote Control The controller supports manual front-panel operation as well as RS232 remote control.
Automatic Overload Protection Integrated protection helps improve reliability when operating industrial LED lighting systems.
External Trigger Support High-speed optocoupler-isolated triggering provides fast response for automated machine vision applications.
Selectable Trigger Level High-level and low-level external triggering can be selected for flexible system integration.
Stable Illumination for Machine Vision
![POMEAS LED controller performance features for machine vision lighting]()
Stable illumination is important for maintaining consistent image brightness, contrast and inspection results. The GE Series uses constant-current LED control circuitry to help maintain stable light output across different brightness settings.
Constant-Current Control Designed to provide stable LED driving performance across different brightness settings.
Constant-Current Accuracy Constant-current accuracy is specified at 5%.
High Conversion Efficiency Conversion efficiency is specified at more than 95%.
Rotary Encoder Adjustment Rotary controls improve manual brightness setting efficiency and ease of operation.
Isolated RS232 Interface The isolated communication interface supports hot plugging and helps protect connected PCs and instruments from electrostatic interference.
Wide-Range AC Input The controller supports AC 110–220 V input for industrial installations.
