  • Page 7: General Description

    LTDVE2CH-20F | INSTRUCTIONS MANUAL 4. General description Any machine vision application employs some kind of light controller. Light controllers are widely used to both optimize illumination intensity and obtain repeatable trigger sequencing between lights and vision cameras. This controller is a compact unit that includes power supply conditioning, intensity control, timing generation and advanced triggering functions.

  • Page 8: Getting Started

    LTDVE2CH-20F | INSTRUCTIONS MANUAL  High current, up to 40 A (with a resolution of 40 mA) The controller must be powered with a fixed supply voltage of 24 V. There is an internal DC/DC converter that can be programmed to provide any voltage between 5 V and 190 V for supplying the output drivers.

  • Page 9: Calculating Generated Heat Per Channel

    LTDVE2CH-20F | INSTRUCTIONS MANUAL The maximum permissible controller heatsink temperature is 90 °C. If the heatsink temperature rises above 90 °C, the controller switches off all the output channels. Output channels are then reactivated once temperature falls below 80 °C.
