Kele Fluorescent/LED Dimming Control Module LDIM2

Kele Fluorescent/LED Dimming Control Module


The Kele Model LDIM2 is a fluorescent/LED dimming control for dimmable electronic fluorescent ballasts/LED driver module. It is designed for single 0-10V dimming output with a 0-10V input or a PWM input from BAS controllers. Feedback is provided for light level setpoint and light level output. The LDIM2 output interfaces with electronic fluorescent ballasts/LED driver modules designed for an analog 0-10V sinking input.
